Unlike earlier stable branches, +we do allow some new features here, if they are not too invasive. +Otherwise, this branch is only for bug-fixes. + + +Overview of Changes from GIMP 2.10.32 to GIMP 2.10.34 +===================================================== + +Core: + + - Check for updates now works on macOS (backported from 2.99.14). + - Update help IDs for better integration with the documentation website. + - Symmetry dockable contents is now shown, yet deactivated, when no images are + opened, improving discoverability (backported from 2.99.14). + - DBus fully disabled on macOS (in some case, it could even freeze GIMP + process when dbus is present yet not responding). Open With feature (e.g. + from file browsers) still work fine as it uses a different code path on + macOS. Other features using dbus (opening files or running batch commands + from a separate GIMP process) won't work, but they probably never did on + macOS anyway. + - "Canvas Size" dialog took too much vertical space and now better uses the + horizontal space by moving the preview and offset fiels to the right side, + and the "Center" button just below (backported from 2.99.8). + - Template selector (backported from 2.99.6) in resize dialog. + - Color scale preferences (0..255/0..100 and LCh/HSV settings in Colors + selection dialogs) are now remembered across sessions. + - Eye icon header added to the item tree views to make it more obvious where + to click for item visibility and links (backported from 2.99.10) + - Revert color proofing behavior changed in 2.10.32 which resulted in + inconsistent past workflows. + - "Lock path strokes" tooltip for the dockable icon was renamed "Lock path". + +Plug-ins: + + - DDS: make GUI translatable. + - file-raw: added high bit depth precision export (partial backport from + 2.99.12). + - TIFF: + * Various bug fixes; + * better check for invalid resolutions on import; + * do not generated warnings for incorrect RichTIFFIPTC tags produced by + Adobe products (only output a message to stderr, for not completely + ignoring these); + * Loading "reduced" image or not is now an option. We use a heuristic for + the default value of said option (trying to guess if it's a thumbnail by + using common usage), but final decision is now up to one knowing the image + you load (backported from 2.99.14); + * Default TIFF export format is "normal" TIFF, not BigTIFF (making it + default was definitely an error in 2.10.32). + - PSD: + * Various bug fixes; + * Useless physical unit conversion removed; + * Backported improvement (2.99.10) for importing layers with clipping set + (leading to color bleeding); + * Backported improvements (2.99.10) for importing clipping layers; + * Paths are now exported (backported from 2.99.14). + - WebP: more informative error messages in some cases. + - Flame: various bug fixes. + - JPEG-XL: + * metadata import backported from 2.99.14 - (requires libjxl 0.7.0) + * Partial backport (2.99.8) of JPEG-XL export; export is always in 8bit + lossless. + - HEIF: various bug fixes. + - Dicom: various bug fixes. + - help: + * macOS: https support now working fine for help files (bypassing + lack of support in GIO for macOS platform). + - animation-play: fixed on macOS. + - PDF: + * Import: new option "Fill transparent areas with white" to fill the + background in white (ON by default as most office PDF writers seem to rely + on readers filling the background with white), allowing importing + transparent PDF files. + * Export: new option "Fill transparent areas with background color" allowing + to decide whether to export a PDF with transparent background. + - TGA: + * Added a workaround to load wrongful TGA files exported by Krita (which + they fixed on their side too now, see Krita bug 464484). + - ICO and CUR: + * Magics detection for these formats has been removed (now using only using + filename extension) because it was interfering with the detection of + certain types of TGA images (which are likely more common than ICO and CUR + files, and extension for these should be reliable enough). + +Libgimpbase: + + - GimpMetadata API (in particular the gimp_metadata_set_from_*() functions) + are now much less memory-hungry (backported from the main dev branch) when + using GExiv 0.12.2 or over. With some huge metadata, it could cause long + freeze or even crashes of plug-ins. + +Libgimpwidgets: + + - Color-picking with X11 is now the default when compiled with X11, even if a + color-picking portal also exists, because it is always right, whereas + portals return color in display space without the space information itself + (i.e. without profiles). + - New dedicated GimpPickButton implementation for Windows (backported from + 2.99.14). + +Libgimp: + + - New wrapper functions around GEGL ops, which also map to items in our Color + menu: + * gimp_drawable_shadows_highlights() + * gimp_drawable_extract_component() + +Build: + + - Bumping minimum GEGL to version 0.4.38. + - Bumping minimum libjxl to version 0.7.0. + - New GIMP_RELEASE macro to tell if code is a release or in-between release + (different from GIMP_UNSTABLE which was telling if we are in a stable or + development branch). + - Our stable CI now uses Debian stable where Python2 is still present. + + +Overview of Changes from GIMP 2.10.30 to GIMP 2.10.32 +===================================================== + +Core: + + - Adding support for localized glyphs ('locl') in Text tool depending + on the value of the "Language" field in Text tool options. + - XCF import nows drop Xmp.photoshop.DocumentAncestors tags after 1000 + of them, similarly to what libgimpbase now does. This could happen + in XCF files which were created e.g. from a PSD import before we + handled the issue in libgimpbase. + - XCF import: + * made more robust by ignoring (with a warning) invalid + parasites and continuing to load the rest of the file (which might + be valid). This way, we are able to salvage more cases of + partially corrupted XCF files. + * additional safety checks to detect broken XCF files. + - Version check can be globally disabled through a value in the + `gimp-release` file. This would allow to use the same build on + repositories with an update channels (where we don't want update + check notifications) and on standalone (where we want them). + +User Interface: + + - Removed titlebar/borders from Windows Splash Screen. + - All official themes now have on-hover indicator around eye and link + toggles in Layer/Channel/Path Dialog tree-views. + - Dark theme: + * Hover-on effect on radio menu items to improve readability. + - Color icon theme: + * Thin contrast border for 'close' and 'detach' to improve their + readability against dark backgrounds on mouse-hover. + +Plug-ins: + + - TGA: improving indexed images with alpha channel support (both + import and export). + - DICOM: Fix endian conversion for photometric interpretation + "MONOCHROME1". + - file-raw: "RGB Save Type" confusing dialog label renamed to "Palette + Type" as on the main dev branch. + - screenshot: option to capture cursor in now available on Windows. + - pygimp: new optional parameter `run_mode_param` (defaulting to True) + to register() function of the Python binding, which allows to make + the "run-mode" parameter optional when creating a new PDB procedure. + This is already used to fix "file-openraster-load-thumb" without + changing its signature. + - BMP: new PDB procedure "file-bmp-save2" which supports all options + available interactively. + - BigTIFF: our TIFF plug-in now officially supports BigTIFF import and + export. + * Import was actually already working transparently if you had + a recent enough libtiff. Now the recent libtiff is enforced by + dependency requirements. + * Export support was added with a checkbox in the interactive dialog + and a new "bigtiff" argument in the "file-tiff-save" PDB + procedure. + * When an interactive export of ClassicTIFF fails for the explicit + reason of "Maximum TIFF file size exceeded", the export dialog is + raised again with a message proposing to try again as BigTIFF or + trying another compression algorithm. + This allows because discoverability and understandibility of the + issue, while not forcing BigTIFF export (since it might not be + supported everywhere). + * Unlike the same change on the main dev branch, this backport comes + without a dependency requirement bump, which means this will only + work if GIMP is built with recent enough libtiff. + - Raw: more robust load able to load as much as possible from the + file, then fill the rest with white, when offset and dimensions are + bigger than actual file size. + - Improved support of a few plug-in code for building under UCRT + Windows environment (more modern C runtime library than MINGW). + - EPS: loading transparent EPS files now supported. + - JPEG XL: import backported from the `master` (2.99) branch. + - WebP: export has a new IPTC checkbox (saved through XMP) as well as + a thumbnail checkbox. (backported from dev branch, since 2.99.8) + - DDS: export has a new flip option (useful for some game engine) as + well as a new savetype option to export all visible layers (not only + the active one). + - TIFF: + * import support for 8 and 16 bit CMYK(A) TIFF files. + * 1, 2 and 4-bit B/W images are now converted to indexed rather than + grayscale as it seems that there is more of a use case for these + images to be handled as indexed, even though technically they can + be considered grayscale. + In the future we could add an option at loading time where the + user can choose whether they prefer it to be loaded as indexed or + grayscale. + * Fix loading images generated by MATLAB's blockproc function. + * More robust loading for 8 bps grayscale MINISWHITE TIFF. + +Libgimp: + + - New gimp_plug_in_error_quark() as a generic GQuark/GError domain for + plug-ins (backported from 2.99.6). + - gimp_drawable_brightness_contrast() now works in the [-1.0, 1.0] + range (it's more of a fix than a change because it's what it should + have been from the start). + - Better management of modification time in metadata: IPTC tag + Iptc.Application2.DateCreated is not overridden anymore as it is the + original creation date of the image. Instead we set the XMP tag + Xmp.xmp.ModifyDate for file modification time and + Xmp.xmp.MetadataDate for metadata modification time. + - Format of Xmp.tiff.DateTime is now properly set with timezone as a + consequence of the previous improvement. + +Libgimpbase: + + - Limit to 1000 ancestors when importing images with incredible amount + of `Xmp.photoshop.DocumentAncestors` tags, which is most likely due + to a bug in some versions of Photoshop (in some PSDs, we encountered + over 100,000 such tags; it probably makes no sense that a document + could have that many ancestor documents). GIMP will now stops at + 1000 such tags before dropping the rest and continue loading the + file. + +Icons: + + - Chain icons for the Color icon theme reworked from the Symbolic + versions (with contrast borders to work on any background color) so + that the "broken" and full variants are easily distinguishable. + +Translations: + + - New Galician and Georgian translations for the Windows installer. + - 20 translations were updated: Catalan, Chinese (China), Croatian, + Danish, Dutch, Finnish, French, Georgian, German, Hungarian, + Icelandic, Italian, Polish, Portuguese, Russian, Slovenian, Spanish, + Swedish, Turkish, Ukrainian. + +Build: + + - Bumping minimum GEGL to version 0.4.36. + - The Windows installer now has an option /DISABLECHECKUPDATE=true to + install the same build but editing the `gimp-release` file to + disable update check as newly implemented (see above in Core + section). + + +Overview of Changes from GIMP 2.10.28 to GIMP 2.10.30 +===================================================== + +Core: + + - Do not follow subpixel font rendering choice from system settings + for text layer rendering. These systems are useful for GUI + rendering on a screen of a specific type and pixel order. Yet when + rendering an image which can be zoomed in or out, showed on various + screens or even printed, subpixel font rendering doesn't make sense. + - Rewrite the core selection drawing logics so that it works on macOS + Big Sur and over. This is a backport (adapted to GTK+2) of the fix + brought in GIMP 2.99.8 for Wayland and macOS. + - Ignore MakerNote metadata tag at export and only store the tags that + go in it, hence avoiding partial invalid metadata. + - Color picking from Colors dockable can now use the Freedesktop + portal. + - On Windows, move from GetICMProfile() to WcsGetDefaultColorProfile() + because the former is broken in Windows 11. + +Plug-ins: + + - metadata-viewer: improve how XMP tags with multiple values are + handled and shown (now each value on a separate line for better + readability). + - metadata-editor: + * XMP array tags of type BAG and SEQ are now on separate lines. + * Comparing XMP tags with equivalent IPTC tags with multiple values, + each value is compared individually, instead of comparing the list + as a whole. + - Many robustness improvements and other fixes to the metadata + plug-ins. + - AVIF: prefer AOM encoder for export (rather than "rav1e", default of + libheif, yet with worse performance). + - PSD: + * Skip sanity check for mask of rendered layers as some layer mask + have invalid dimensions in such cases. They will now be loaded + correctly. + * Fixed loading of CMYK PSD files without alpha. + * Fixed loading of CMYK images without layers. + * Fixed loading of merged image of a 16 bit per channel RGBA PSD + file with the alpha channel opaque. + - PBM: large file export now always works and does not depend anymore + on the platform's long int size. + - Screenshot: + * GNOME shell implementation dropped because the D-Bus API has been + restricted to core components for security reasons, thus our + plug-in was failing. + * KDE portal moved as last fallback after the X implementation + (when running on X) and Freedesktop portal, because KDE is also + starting to block API calls for security reasons. + +Installer: + + - Extension .avif now associated to GIMP. + - Drop codepage conversion, use UTF-8 for language files. + +Build: + + - macOS support officially bumped to macOS 10.12 (Sierra). We would + usually try to avoid doing this within a stable release but the + conditions (lack of contributors) is such that it is hard to avoid. + + +Overview of Changes from GIMP 2.10.26 to GIMP 2.10.28 +===================================================== + +Translations: + + - 10 translations were updated: Catalan, Chinese (China), Finnish, + Italian, Polish, Russian, Slovenian, Spanish, Swedish and Ukrainian. + +Build: + + - Fix uninstalled white-border prelight file. + + +Overview of Changes from GIMP 2.10.24 to GIMP 2.10.26 +===================================================== + +Core: + + - Dashboard now has memory support in OpenBSD. + - Default shortcuts Shift+[ and ] for tool size changed to { and }. + - Performance improvements for GIMP on macOS Big Sur: these + improvements were actually already applied in our macOS packages + since GIMP 2.10.22, but were applied upstream directly only now. + +User Interface: + + - Dark theme: improve accessibility of GtkRadioButton by adding a + white border on mouse-hover. + - Gray theme: set light background for selected text in Layers and + Paths dockable dialogs to make text visible. + - Dark, Gray and Light themes: remove 3D shadow box around eye and + link toggles in Layers, Channels, and Paths dockable dialog tree + views. + +Plug-ins: + + - Improved DDS support and fix some red/blue bit swap for RGB10A2 DDS. + The plug-in version is incremented so that it is able to catch and + correct previously incorrect RGB10A2 images exported by older + versions of our plug-in. + - DDS files with "L16" - a 16 bit luminance channel - are now loaded + in 16-bit. + - DICOM images: + * Support for planar configuration. + * Support for deprecated big endian transfer. + - TIFF images: + * Thumbnail storing now done by storing the thumbnail as the second + page in the file (through Exiv2) and setting metadata + "Exif.Thumbnail.NewSubfileType" to 1 (reduced resolution image) + instead of storing the thumbnail as a subifd. This was done + because of a Windows bug locking TIFF files with thumbnail stored + as subfid. + * Symmetrically, loading will ignore pages marked as "reduced + resolution image" (i.e. it will consider them as thumbnails), as + well as try to guess if a page (without subfile type) is a + thumbnail when it meets following criteria: second page with YCbCr + PhotometricInterpretation, old style jpeg compression while the + first page has a different PhotometricInterpretation or + compression. + +Script-fu: + + - New (dir-make "/dir/name" mode) function to create a directory. + +Translations: + + - New translations for the Windows installer: Vietnamese, Lithuanian. + - 13 translations were updated: Catalan, Chinese (China), Croatian, + Dutch, German, Lithuanian, Polish, Russian, Slovenian, Spanish, + Swedish, Ukrainian and Vietnamese. + +Build: + + - On Windows, *.rs file extension is not associated with SUN Raster + images anymore. The reason is that this file extension is mostly + used for Rust code files nowadays. If Windows could detect file + formats with "magic numbers" (i.e. byte identifiers), it would not + be a problem, but since it relies apparently only the extension, + it's better to remove this association. + - Oppositely on Linux and other Unix-like systems using desktop files, + add the image/x-sun-raster MimeType which was forgotten (there, + detection should be fine and not depend on file extension). + - gimp30-tips.mo is not installed anymore (only used during the build + to generate gimp-tips.xml with multiple language support). + - --enable-check-update now has an "auto" value, which is the new + default. It is equivalent to "yes" for Windows and macOS and "no" in + all other cases. + - New unit test to check that localizations listed in the installer + script match available po files in po-windows-installer/. + - "msys*" host value now detected as Windows builds. + - Bumping minimum GEGL to version 0.4.32. + + +Overview of Changes from GIMP 2.10.22 to GIMP 2.10.24 +===================================================== + +Core: + + - Ignore Pentax and PentaxDng metadata at export because they are + unsupported. + - DBus calls (remote file open, typically with double click on file + browser; and remote command run) are now processed after all command + line files (in case of calls during startup) and in the call order + (FIFO) for consistency. Some timeout has also been added to not spam + the core process with non-processable DBus calls during startup. + - Display profile name in "Color space" field of Image Properties and + improve ellipsis & wrap on dialog fields whose contents' size is not + controllable together with better dialog size management. + - Fix stack overflow when loading very large XCF files on Windows. + - Point snapping now works outside the canvas. This is used for snap + to guides, grid and vectors. Snap to grid only works off-canvas when + "Show All" is enabled because off-canvas grid is not visible + otherwise, though snap to guide and vectors will always work + off-canvas. + +Libgimp: + + - Various metadata improvements: + * Improve reading of iptc tags that appear more than once. + +Plug-ins: + + - JPEG export will better advertize when metadata export fails, + possibly with relevant error message. Image export would not fail, + but at least we make the person aware metadata is not properly + exported. + - More robust TIFF import and export: + * Better handling of Exif.Thumbnail.* tags on export. + * Import now ignores TIFF pages with invalid directory (rather than + freezing and output an error to warn of possible data loss). + * Import attempts to count the directories by reading them when the + headers does not announce any directory, which allows to salvage + images with improper header. Also if reading of a directory fail, + we now output a message to warn of possible data loss. + * Fixed loading 2 and 4-bit TIFF images in grayscale and indexed. + * Improve support of ExtraSamples fields with non-conformant TIFF + files. + * Improve loading of multi page tiffs with linear TRC. + * More safety checks as a result of fuzz-testing. + * Improve loading of MinIsWhite and MinIsBlack images. + - GeoTIFF tag support added (recognized and stored into image + parasites at import, then exported back when TIFF format is used) + with appropriate "Save GeoTIFF data" checkbox (checked by default + and sensitive only when the metadata parasite is present) to disable + GeoTIFF metadata export when not desired. + - The metadata viewer and editor got a big cleaning and refactoring + pass, as well as various fixes and several improvements: + * Fix handling of IPTC tags which can appear more than once (such as + "Keywords") in both the viewer and editor. + * Always read both the IPTC and XMP equivalent tags in the editor, + instead of assuming they are necessarily the same. + * More IPTC equivalents of XMP tags added: + + Iptc.Application2.LocationName <=> Xmp.iptc.Location + + Iptc.Application2.BylineTitle <=> Xmp.photoshop.AuthorsPosition + + Iptc.Application2.CountryCode <=> Xmp.iptc.CountryCode + + Iptc.Application2.Writer <=> Xmp.photoshop.CaptionWriter + * The editor now properly saves IPTC tags. + * Improve UTF-8 conversion to avoid double string conversion (hence + actually breaking encoding). + * Use proper unit abbreviations and proper label casing. + * GPS data is now properly formatted with better precision and with + translatable string parts and tooltips are added to explain how to + correctly edit GPS data (latitude, longitude, altitude). + Also seconds part of latitude/longitude is now saved with more + precision and altitude details now switch from .1m to .10m. + * Better error reporting when the editor fails to write a tag, with + proper GUI error, so that such error do not go unseen. + * Better error handling when closing the editor or viewer too, and + improve error handling when the calendar dialog fails. + * Use a logging domain for debugging-only messages which pollutes + the output. + * Xmp.iptc.CreatorContactInfo/Iptc4xmpCore:* override the shorter + forms Xmp.iptc.Ci* if both are present, since the longer form is + more common. + * Improve saving of XMP metadata. + * And more bug fixes and refactoring steps to get rid of duplicate + code. + - PNG will now prompt only for layer offset different from zero. Some + software were always setting an offset of 0 (e.g.: POV-Ray v3.7) so + GIMP would unecessarily prompt the user until now for PNG created by + such software. + - BMP: + * allow loading of BMP images with incorrect BI_BITFIELDS + compression. + * support loading more bit depth such as 24bpp images. + - file-darktable: + * support updated Lua API of darktable 3.6 and beyond; + * Adding environment contents to debugging output when + DARKTABLE_DEBUG env variable is set. + - PDF import: + * New option to reverse order of layer. + * Support fractional DPI (allowing accurate page dimensions). + - DDS: + * Set blue channel of BC5 dds images to 0 instead of 255. + * Fix DDS BC5 compression/decompression with Red and Blue swapped. + We detect images created by an older GIMP on loading and swap the + channels back. + - HEIF: + * Removes the "HDR" mention on HEIF 10/12-bit export because high + bit depth does not necessarily means HDR. + * Runtime detection of HEIC and AVIF file formats (depending on + available encoders and decoders), which allows afterwards update + of the dependency, but also allows usage for a single format (e.g. + for distributions which want to support only AVIF). + * With libheif 1.10, visually lossless export is possible for + 10/12 bit depths too + - PSD: + * More flexible reading of layer mask record size, skipping invalid + or unsupported mask info size, hence allowing us to load more PSD + files (at least the part of a PSD we support instead of failing + the whole import altogether). + - G3 fax images: + * Improve error handling when loading. + * Be more forgiving on bad lines which were quite frequent on older + fax images, allowing to salvage some old images. + +Build: + + - Some configure fixes for autoconf-2.70 support. + - Adwaita's legacy "software-update-available" icon is now bundled + with GIMP to handle the possibility of them being absent from your + system theme (typically it was missing on our Windows build). + +Installer: + + - New Slovak translation. + +Translations: + + - Kabyle translation added. + +Build: + + - Bumping minimum GEGL to version 0.4.30. + + +Overview of Changes from GIMP 2.10.20 to GIMP 2.10.22 +===================================================== + +Core: + + - Verbose version information (`gimp-2.10 -v` on command line, or + debug output) now displays Flatpak related information when + available. This is especially useful for debugging (such as the + exact Flatpak build hash, the runtime version, the installed + Flatpak extensions, permissions, etc.). + - OpenCL settings has now been moved to the Playground tab in + Preferences. + - On stable builds, "Playground" tab is now visible in Preferences if + any of the experimental features has been enabled, even without the + CLI option `--show-playground`. + +Tools: + + - "gegl:matting-levin" now the default engine of Foreground Select + tool (when present, as it is an optional feature) as it performs a + lot better. + - GEGL operations now display a "Sample merged" checkbox in Tool + Options. This will be used when the operation allows to pick a color + (hence one can pick from the edited layer or from visible data). + - "Sample merged" now defaults to being activated in Color Picker and + GEGL tools as it seems the less confusing for beginners who don't + know of the option yet (according to a small poll we ran). + +User interface: + + - In GimpSpinButton, don't propagate Enter key-press events if + updating the spin-button's value in response changes the entered + text. This prevents confirming dialogs when hitting Enter after + entering a math expression in size entries, updating their value + instead. + Likewise, don't propagate Escape key-press events if a new value was + entered, and restore the original value instead. + - GimpMemSizeEntry improved to show appropriate binary prefixes + (kibibyte, mebibyte and gibibyte) instead of decimal ones, to round + properly when using higher units, and to not lose accuracy when + possible when displaying in higher units. + - Several of the biggest pages of the Preferences dialog are now + scrollable, allowing the dialog to fit on smaller displays. + +Plug-ins: + + - Add a new GIMP_EXPORT_NEEDS_CROP export capability, which causes + gimp_export_image() to crop the exported image content to the image + bounds; this is useful for formats that support layers, but have no + concept of global image bounds, hence cropping is the only way to + enforce the image bounds. + When showing the export dialog, give an option to either crop the + layers to the image bounds, or to resize the image to fit the + layers. + - Content type `image/webp` is now recognized (and not only + `image/x-webp` as both seem to be in used and this format is + unfortunately not yet listed in IANA media types (so various content + types are in use, no clear standard apparently). + - DDS import is now a bit more permissive, allowing to load some files + with invalid header flags regarding compression, while we are able + to know the right compression from other flags. This allows to + recover invalid DDS files exported by other software. + - JPEG detection improved to be more generic and reliable. + - HEIF support improvements: + - AVIF importing and exporting added (requires libheif 1.8.0+) + - 10/12-bit importing and exporting now available for HEIC/AVIF + - NCLX color profile import (link with LittleCMS) + - Metadata support when importing + - "Lossless" option is now called "Nearly lossless (YUV420 format)" + because this is actually what it is, hence previous naming was + misleading. + - TIFF support improvements: + - Add an option to crop the layers to the image bounds when exporting + individual layers (using GIMP_EXPORT_NEEDS_CROP), since TIFF has no + concept of global image bounds otherwise. Cropping is enabled + by default. + - TIFF export will not override "DocumentName" metadata tag anymore. + - Stop writing file paths into TIFF DocumentNames as file paths can + contain confidential information such as usernames and directory + structures, making the previous behaviour a potential privacy and + security risk. + - Fix a file descriptor leak case which may have prevented a file + from being opened on Windows. + - Multiple improvements in the PSP import plug-in: + - support reading raster layers of PSP version > 6, + - support reading 16-bit integer PSP files, + - support reading grayscale and indexed PSP files, + - support PSP images with zero-length layer names, + - fix wrong layer offset of layers, + - fix reading layer names with high bit ASCII characters, + - fix incorrect loading of PSP images with uncompressed channel data, + - fix reading of creator block data of PSP images, + - better error messages describing yet unsupported features, + - improve reader stability by always using the block/chunk length. + - Spyrogimp now works on Grayscale images and clutters less the undo + history. + - "Orientation" metadata is now reset whether you accepted to rotate + the image or not when importing an image. + - XPM does not export a "None" (transparent) color when unused. + - BMP always include color masks when exporting BMP with color space + info, as mandated by BITMAPV5HEADER specification. + +Debugging: + + - Add progressive performance logs: progressive logs contain complete + information after each recorded sample, by writing partial address + maps at each sample, containing all new addresses introduced by the + sample. + This allows recording complete logs even in cases where they can't + be properly terminated, such as when GIMP crashes or freezes in the + middle of the log. + Progressive logs are disabled by default, since they potentially + increase the sampling cost. They can be enabled through a toggle + in the log file-dialog, or through GIMP_PERFORMANCE_LOG_PROGRESSIVE + environment variable. + Performance log viewer can now process progressive performance logs + too. + - Allow controlling performance-log parameters through the UI. + +Build: + + - new `distcheck` step in Continuous Integration. + +Bug fixes: + + #2275, #2668, #2874, #3481, #3868, #4061, #4155, #4328, #4505, #4536, + #4560, #4816, #5043, #5069, #5208, #5219, #5226, #5232, #5274, #5275, + #5357, #5358, #5472, #5530, #5584, #5592, #5623, #5630, #5651 + +Translation updates: + + - Basque, Catalan, Chinese (China), Croatian, Danish, French, German, + Italian, Japanese, Kazakh, Polish, Russian, Spanish, Swedish, Turkish, + Ukrainian + +Developers/contributors: + + - Daniel a Simona Novomeská, David A.

The option is unchecked by default, + as it is the non-destructive behavior, which also means the + default behavior is changed. + - Crop tool in image crop mode will not crop layers with "Lock + pixels" on, anymore, even if "Delete cropped pixels" is checked. + - Painting tools can now restore opacity and blend mode from + presets. + +User interface: + + - Image / Precision renamed to Image > Encoding + - Tool groups can now display their tool list on hover rather than + on click. This can be set in Preferences, in the Toolbox tab. + - Improved update notification GUI in About dialog, and now also + showing an update comment when one was set in gimp_versions.json. + - Palette Editor dockable: the color index in the current palette is + now shown in front of the color name. + +Plugins: + + - In file-psd, make the data_start and data_len fields of the + PSDimageres and PSDlayerres structs unsigned, to avoid potential + overflow/sign-extension + - file-raw: Canon CR3 files are now properly recognized by GIMP and + sent to your raw developer software of choice. + - PNG and TIFF export: "Save color values from transparent pixels" + defaults now to not saving color values (i.e. channels set to 0) + when alpha channel is present and 0 itself. + - PDF import: multi-pages are now imported in bottom-first order, + similar to animated formats, and also similar to defaults for PDF + export. This brings consistency but break existing behavior, hence + needs to be noted. + - Added support for exporting 16-bit PSDs, read and write channels + from/to PSd in the right order + +Filters: + + - The 'Vignette' filter now has on-canvas controls + - New 'Filters -> Blur -> Focus Blur' filter with on-canvas controls + to emulate out-of-focus blurring + - New 'Filters -> Blur -> Variable Blur' filter that uses an aux + mask input to blur an image with variable intensity + - New 'Filters -> Light and Shadow -> Bloom' filter + +Updated translations: + + - British English, Catalan, Chinese (Taiwan), Dutch, Finnish, + German, Greek, Italian, Korean, Polish, Romanian, Russian, + Spanish, Swedish, Turkish, Ukrainian + +Icons: + + - Replace fileicon.ico with version contain 24x24, 64x64, 128x128, + and 256x256 sizes for Windows icon + - Replace wilber.ico with version containing 128x128 size of Windows + icon + +Bug fixes: + + - #189, #354, #872, #1439, #3405, #3533, #3558, #3777, #3841, #4094, + #4328, #4363, #4487, #4618, #4641, #4663, #4696, #4734, #4745, + ##4793, 4827, #4846, #4858, #4871, #4895, #4904, #4919, #4967, + ##4968, #4992, 4996, #5009, #5010, #5033 + +Developers: + + - Ell, Jehan, lillolollo, Marco Ciampa, Michael Natterer, Øyvind + Kolås, pesder, Salamandar, Sergio Jiménez Herena, Simon Budig, T + Collins, woob + +Contributors: + + - Nikc, Sabri Ünal, Michael Schumacher, Jernej Simončič, luz.paz + +Translators: + + - Alexandre Prokoudine, Anders Jonsson, Bruce Cowan, Cristian + Secară, Daniel Korostil, Daniel Șerbănescu, Dimitris Spingos, Jiri + Grönroos, Jordi Mas, Nathan Follens, Piotr Drąg, Rodrigo Lledó + Milanca, Sabri Ünal, Seong-ho Cho, Tim Sabsch, Yuri Chornoivan, + Георгий Тимофеевский + + +Overview of Changes from GIMP 2.10.16 to GIMP 2.10.18 +===================================================== + +Core: + + - In gimp:replace, when compositing the same content over itself, + i.e., when the input and aux buffers share the same storage and + same tile alignment, pass the input buffer directly as output, + instead of doing actual processing. In particular, this happens + when processing a pass-through group outside of its actual bounds. + +User interface: + + - Add new Symbolic-High-Contrast and Symbolic-Inverted-High-Contrast + themes, which are automatically-generated high-contrast variants + of the (original) Symbolic theme. The contrast factor is settable + in the makefile, and is currently at 1.5 for both themes. + + - Rename tools/invert-svg to tools/svg-contrast, which now takes a + contrast-factor argument, and adjusts the input SVG contrast, + instead of just inverting it. Note that we can still use the tool + to invert icons, using a contrast of -1. + + - Allow horizontal scrollbars in all the Preferences dialog tree- + views, so that they don't limit the minimal width of the dialog + (in particular, the UI- and icon-theme tree-views may contain + arbitrarily-long paths). + + - Draw a border around the color FG/BG color areas as a pair of + black and white rectangles instead of letting GTK do this. This + imporoves the legibility of borders, especially in dark themes. + +Tools: + + - In GimpPaintTool, when not snapping brush outline to stroke, make + sure to properly snap the cursor position to 15-degree angle + multiples in line mode, not only when painting the line, but also + during motion. + +Plug-ins: + + - Add naive support for CMYK 8-bit PSD files + +Updated translations: + + - Basque, Catalan, Danish, Polish, Spanish, Swedish, Ukrainian + +Bug fixes: + + - #4643, #4634 + +Developers: + + - Ell, Massimo Valentini + +Translators: + + - Alan Mortensen, Anders Jonsson, Asier Sarasua Garmendia, Daniel + Korostil, Jordi Mas, Piotr Drąg, Rodrigo Lledó Milanca + + +Overview of Changes from GIMP 2.10.14 to GIMP 2.10.16 +===================================================== + +Core: + + - In gimp_gegl_apply_cached_operation(), use gint64 for storing the + total and processed pixel counts used for reporting progress, to + avoid overflowing when applying an operation to a large image. + + - In GimpFilterTool and gimp_drawable_apply_operation(), use + gimp_drawable_filter_set_add_alpha() to add an alpha channel when + applying an operation that specifies "needs-alpha" to a drawable + that can have alpha. + + - In GimpFilterTool, move all the drawable-filter option setup to a + new gimp_filter_tool_update_filter() function, and call it + whenever the drawable-filter's options need to be updated. This + avoids duplicating logic in various places. + + - Improve the efficiency of decoding RLE data when loading ABR + brushes, by reading entire scanlines into a buffer all-at-once, + instead of reading the stream byte-by-byte. + + - GIMP now optionally phones home to find out if there's a new + version available and then tells the user if there is one + indeed. It also keeps track of the installer revision and then + warns if there's a newer installer available. This can be disabled + in Preferences. In that case, users still have the option to + manually check for an update via the About dialog. The feature can + be disabled entirely with the '--disable-check-update' configure + switch. + +Tools: + + - New 3D Transform tool where you can set vanishing point, camera's + focal length, and the move and rotate layer, selection, path, or + image in 2.5 space. With the "Unified interaction" option enabled, + all three interaction modes of the grid (camera, move, and rotate) + are available simultaneously. In this mode, the inner and outer + regions of the item are used for moving and rotation, respectively, + and the vanishing point is controlled through through a handle. + + - Transform tools now respect the Clip option and update the canvas + preview accordingly. + + - New "Composited preview" option allows respecting layer's blending + mode and position in the layer stack rather than rendering it as + an overlay on top of the overall layer stack. This simplifies + creating complex layer compositions greatly. The option requires + mipmaps to be used and thus is disabled by default. It also comes + with an experimental "Synchronous preview" suboption to render the + composited preview synchronously. This reduces the lag for + painting the preview, but can harm responsiveness for bigger + images, where rendering the preview is slow. + + - Add a new "Preview linked items" option to the transform-grid + tools. When this option is enabled, together with composited + previews, the transform preview includes all linked layers and + channels when transforming a layer/channel. Paths are currently + unsupported. + + - New widget called GimpPivotSelector, a 3x3 grid of toggle buttons, + is now used for selecting a natural pivot position (e.g. for a + transform) relative to an item: its center, its corners, and the + midpoints of its edges. Currently used in Rotate and 3D Transform + tools. + + - Add "Show all" support to the Bucket Fill tool in line-art mode + + - Color picker and sample points now support displaying values in + Yu'v' (CIE 1976 UCS) color space. + + - The Symmetry Painting dock now has an "Enable reflection" option + that allows painting patterns resembling a kaleidoscope. + + - Transform clipping is temporarily disabled for layer groups. No + preview other than 'Adjust' works anyway. This will be fixed later + on. + + - Construct a box-filtered mipmap hierarchy for the original brush + on-demand, and the closest mipmap is used as the resampling source + for downscaled brushes, significantly improving the output + quality. + + - Now that painting is done in a separate thread, the display update + rate has a far smaller impact on it. Increase the GimpDisplay + update rate, which handles image updates, to 60 FPS, and the + GimpDrawTool update rate to 120 FPS. In particular, the latter + change makes the brush outline motion much smoother. + + - In the Airbrush tool, increase the maximal stamp FPS from 15 to + 60, and change the corresponding maximal Rate value from 150 to + 100. This technically affects tool presets, but we'll live. + + - Add a new "Snap brush outline to stroke" toggle to the "Image + Windows" preferences page. When enabled, the brush outline in + paint tools snaps to the individual dabs while painting, which is + how it worked before version 2.10.16. Disable the option by + default. This seems to be what most other programs are doing, and + it does give paitning a smoother feel. + + - The Warp Transform tool now respects settings for painting tools: + showing the brush outline, snapping to dabs, and showing the paint + tool cursor. + +UI: + + - Tools are now logically grouped in the toolbox by default. Users + can customize the groups to their liking or disable this feature + altogether in the Preferences dialog (Interface / Toolbox page). + + - New opt-out compact style for sliders with revamped interaction. + The widget uses a narrower layout, and the different + upper/lower-half behavior is gone. Instead, the behavior depends + on the mouse button and modifier used: + + - left-click is used for absolute adjustment, + - Shift + left-click + drag changes value in small increments, + - Ctrl + left-click + drag changes value in large increments, + - middle-click enables numeric input mode; + - right-click enables numeric input mode and selects the value. + + - The "You can drop dockable dialogs here" message is gone from the + toolbox for good. Instead, highlight dockable areas when a user + starts dragging a dockable dialog, and intensify the highlight as + the dialog goes over a dockable area. + + - Consolidate UI for merging down and anchoring layers: + As they are both mutually exclusive and serve an almost identical + purpose, the "Merge down" and "Anchor Layer" are given mutually + exclusive visibility in menus, and the anchor button is replaced + with a merge down button in the Layers dockable whenever there is + no active floating selection. Modifier keys are available: + + - Shift: merge layer group + - Ctrl: merge visible layers + - Ctrl + Shift: merge visible layers from last used values + +Plugins: + + - In plug_in_compat.pdb, when wrapping an op node inside a graph, + set the op node as the graph node's underlying operation. This + allows gimp_gegl_apply_operation() to perform certain + optimizations. + + - The Spyrogimp plugin now features a Visual tab where the inner + mechanics of a spirograph is abstracted away, and you operate on + amount of petals etc. The plugin now also allows saving a pattern + as a path rather than rendering it to a layer as a bitmap. + + - Improve the loading speed for PSD files, mostly by eliminating + excessive copies. + +Filters: + + - Don't disable gegl:color-to-alpha (which has "needs-alpha") + when the drawable doesn't have an alpha channel, if one can be + added. + + - Don't disable color-to-alpha for grayscale drawable, since the + operation is applicable to grayscale images (in particular, it + doesn't add color where there was none), and since GIMP no longer + distinguishes between layers and channels according to the + drawable format when updating the filters actions. + +Windows: + + - Installer: unofficial languages, ghostscript 9.50. + - Installer: skip .debug files when they don't exist. + - Installer: properly remove old icons on 32-bit installs and + per-user installs. + +macOS: + + - Set required variables if it is running from Apple application + bundle. + - The macOS build now ships with the dashboard dock for displaying + performance graphs. + +Updated translations: + + - British English, Catalan, Danish, French, German, Hungarian, + Icelandic, Italian, Japanese, Polish, Russian, Spanish, Swedish, + Turkish, Ukrainian. + +Bugfixes: + + - #4172, #4194, #4205, #4218, #2543, #4185, #4246, #2794, #4209, + #4278, #4372, #4187, #4392, #2674, #4338, #2862, #4203, #4204, + #4354, #1266, #4584, #4174, #4285, #4366, #1975, #4605 + +Developers: + + - Alex Samorukov, Cyril Richard, Elad Shahar, Ell, Elle Stone, + Jehan, Jernej Simončič, lillolollo, Massimo Valentini, Michael + Natterer, Pascal Terjan, woob. + +Translators: + + - Alan Mortensen, Alexandre Prokoudine, Anders Jonsson, Balázs + Meskó, Balázs Úr, Bruce Cowan, Daniel Korostil, Jordi Mas, Julien + Hardelin, Marco Ciampa, Piotr Drąg, Rodrigo Lledó Milanca, Ryuta + Fujii, Sabri Ünal, sicklylife, Sveinn í Felli, Tim Sabsch, Zander + Brown. + + +Overview of Changes from GIMP 2.10.12 to GIMP 2.10.14 +===================================================== + +Core: + + - New "Selected areas continue outside the image" toggle option to + the "Feather Selection" dialog. + - New "Allow editing on non-visible layers" setting in Preferences + to allow painting, transforming, and selecting on layers with + toggled off visibility. + - XCF loading a bit more resilient to corruption: it doesn't stop + any more at the first layer or channel error; instead it tries to + load more layers/channels to salvage as much data as possible from + a corrupted XCF file. + - In gimp:gradient, fix dithering to correspond to how we actually + round float values to 8-bit. In particular, this avoids + introducing noise when a component is fixed at 0 or 1 along a + segment. + - New "Show All" view mode allowing to show pixels outside the + canvas boundary. + - New "Show Canvas Boundary" option to render a dotted line around + the canvas boundary. + - New "Keep Padding in "Show All" Mode" option, also available as a + default option via Preferences, to preserve the padding color + instead of displaying the checkerboard. + - Several features updated to react as expected when run + out-of-canvas: color-picking, canvas grid, transform tools, bucket + fill, and more. + - Loaded images' pixel density will now default to 72 PPI when no + explicit resolution information was stored in the imported file. + Newly created images' default pixel density will continue to be + based on the default image template (with value 300 PPI if it has + not be changed), yet not loaded images anymore. 72 PPI is the + common default in most software (and in standards such as Exif) so + it makes sense we stick to it, only for loaded images. + +Tools: + + - Free Select tool: fast copy|cut-paste modifiers (Alt + Ctrl|Shift) + are now working even when the selection is not committed. Starting + a fast copy|cut-paste will automatically close the polygon and + commit the selection, accelerating fast usage of free selections. + - Foreground Select tool: new "Grayscale" Preview Mode. Also, a + color selector for "Color" preview (original preview mode) now + available, to select any color and opacity for the preview. + - Add a new "Image" transform type to the transform tools, in + addition to the existing "Layer", "Selection", and "Path" + transform types. The "Image" mode transforms the entire image, + rather than a single item. In tools with a preview, the preview + shows the transformed image projection. The clipping mode + controls how the canvas is clipped during the transform; in + particular, the ADJUST clipping mode resizes the canvas to fit its + transformed size. + - In GimpFilterTool, add a new "clipping" option, which can be + either Adjust or Clip. This option is controllable for layers, + when there's no selection mask. + When set to Adjust, which is used by default, the filter's output + may extent past the drawable's boundary, and the drawable will be + resized to match the output when committed. + - Gradient tool: offset support in shaped gradients + +Plug-ins: + + - Simple 8-bit port of filters to GEGL: nl-filter, film, + fractal-explorer, flame, blinds, jigsaw, gradient-flare, + checkerboard, tile-small, curve-bend, sample-colorize, map-object, + lighting, grid, despeckle, sphere-designer, contrast-retinex, hot, + sparkle, cml-explorer, destripe, twain, animation-optimize, + depth-merge, warp, imagemap, gimpressionist + - Port of filters to GEGL with float support: van-gogh-lic. + - Add color profile support for HEIF (only when libheif 1.4.0 is + available). + - TIFF import will now ask (in interactive mode) how to process + unspecified TIFF channels: non-premultiplied (used to be the + default) alpha, premultiplied alpha, or just import as generic + channel. + - HEIF export now improved with same profile logics as JPEG or WebP + (it can actually export higher bit-depth data, so profile logics + should be the one as in PNG, but we only support 8 bpc HEIF for + the time being). + - HEIF export dialog now has a "Save color profile" checkbox + allowing to not export with a profile when needed (needs libheif + 1.4.0 or higher). + - PDF exporting: text layers in layer groups are now exported as + proper text. + - Cleaned up the file-dds GUI, removed the "Advanced" expander. + - gimptool external tool now install plug-ins into subfolders (this + is not mandatory in GIMP 2.10 yet, unlike future GIMP 3, but is + already the recommended folder structure for plug-ins). + - 3 procedures ("color-decode-ycocg", "color-decode-ycocg-scaled" + and "color-decode-alpha-exp") removed from file-dds plug-in + because they are hacks which should stay internal to the plug-in + and are semantically wrong because colors in drawables are never + in such formats. + +Filters: + + - New "Normal Map" filter to generate normal maps from height maps + in the Generic section. + - Replace old filters with GEGL operation counterparts: edge-neon + (gegl:edge-neon), contrast-normalize (gegl:stretch-contrast), + oilify (gegl:oilify) + - Add gegl:bayer-matrix and gegl:linear-sinusoid to Filters -> + Render -> Pattern. + - Add gegl:newsprint to Filters -> Distorts. + - Add gegl:mean-curvature-blur to Filters -> Blur. + +Performance: + + - Add an active-thread variable to the dashboard's misc group, + showing the number of active worker threads. + - Reduce time complexity of layer-group translation. When + translating a layer group, avoid separately updating the original + area of the child layers before translating them (as per the fix + to issue #3484), as this results in quadratic time complexity + w.r.t. to the maximal subgroup nesting level. Instead, simply + defer the updating of the group's offset until *after* translating + the child layers, so that their original area isn't clipped by the + parent, while their new area is still properly updated even if the + parent's size changes. + +User interface: + + - Many mnemonics added in various dialogs. + - Add a gimp-rotate-image-arbitrary action, and a corresponding + "Image -> Transform -> Arbitrary Rotation..." menu entry, which + activates the rotate tool in image mode (similarly to the + corresponding action for layers). + - On Windows, minimized GIMP window is now deiconified when GIMP is + run again (clicking its shortcut or otherwise). + +Preferences: + + - New "Swap compression" option: explicit control over the tile-swap + compression algorithm in GEGL. "Best performance" is used by + default, "Balanced", "Best compression", and "None" (disables + compression) are available. + +Devel docs: + + - Update the libgimpconfig and libgimpbase docs. + - Update docs with missing symbols and types. + - New docs for structs and enums. + +Installers: + + - Install 64-bit Python on 64-bit Windows (until now, the installer + used to install 32-bit Python for all architectures). + - Windows installer now supports per-user install. + +Debugging: + + - New mnemonic-clashes tool to help looking for mnemonic clashes. + +Translations: + + - Basque, Brazilian Portuguese, British English, Catalan, Chinese + (Taiwan), Croatian, Danish, Dutch, French, German, Greek, + Hungarian, Icelandic, Indonesian, Italian, Latvian, Polish, + Russian, Slovenian, Spanish, Swedish, Turkish. + +Bugfixes: + + - #3630, #3226, #3610, #1725, #3093, #3599, #3597, #3082, #3553, #3435, + #3503, #3532, #3164, #3560, #3500, #3493, #3514, #3512, #2685, #3641, + #1002, #360, #3263, #2221, #3893, #2708, #3100, #2873, #3655, #2206, + #3341, #3718, #3763, #3112, #3723, #4049, #4068, #3663, #4119, #4008, + #2837, #3994, #3990, #1283, #2561 + +Code contributors: + + Alexandre Prokoudine, Ell, Federico Mena Quintero, Jehan, Jernej + Simončič, Lionel, Massimo Valentini, Michael Natterer, Michael + Schumacher, Oleksii Samorukov, Sabri Ünal, Sergio Jiménez Herena, + Thomas Manni, lillolollo, sarah, woob, Øyvind Kolås. + +Translators: + + Alan Mortensen, Alexandre Prokoudine, Anders Jonsson, Andika + Triwidada, Asier Sarasua Garmendia, Balázs Meskó, Balázs Úr, Bruce + Cowan, Claude Paroz, Daniel Mustieles García, Dimitris Spingos, + Emin Tufan Çetin, Hannie Dumoleyn, Jordi Mas, Julia Dronova, Julien + Hardelin, Marco Ciampa, Martin Srebotnjak, Milo Ivir, pesder, Piotr + Drąg, Rafael Fontenelle, Rodrigo Lledó Milanca, Rūdolfs Mazurs, + Sabri Ünal, Sveinn í Felli, Tim Sabsch, Zander Brown. + + +Overview of Changes from GIMP 2.10.10 to GIMP 2.10.12 +===================================================== + +Core: + + - Add an "Incremental" option to the Dodge/Burn tool, which, + similarly to the Paintbrush, Pencil, and Eraser tools, applies the + effect incrementally as the pointer moves. + - Curves now have a concept of smooth vs corner points: smooth + points produce a smooth curve, while corner points produce a sharp + curve (previously, all points were smooth). + - Search the user font directory path on Windows (since Windows 10, + non-admin users have the ability to install fonts). This is only a + temporary hack until fontconfig adds proper upstream support: + https://gitlab.freedesktop.org/fontconfig/fontconfig/issues/144 + - In gimp_brush_core_get_paint_buffer(), when allocating a new paint + buffer, clear the old buffer *before* allocating the new one, to + reduce the amount of simultaneously allocated memory. + - In GimpPaintbrush, avoid refilling the paint buffer at each dab if + the paint color/pixmap hasn't changed, hence allowing faster + painting in some specific cases. + - Add hygon cpu detection and enable MMX/SSE support. + - Add a GimpSymmetry::get_transform() virtual function and a + corresponding gimp_symmetry_get_transform() function which return + the brush transform corresponding to a given symmetry stroke in + terms of the rotation angle and reflection flag (in contrast to + gimp_symmetry_get_operation() which returns the same transforation + in terms of a GeglNode). This allows us to simplify, fix (artifact + bugs, etc.), and improve the painting-code performance for several + symmetry painting cases. + - New gimp-brush-pipe-spacing parasite set by core code to preserve + GIH brush's spacing across reloads. + - Add a new Offset filter tool, as a front-end to gimp:offset. The + tool replaces, and provides the same interface as the drawable- + offset dialog while also providing live preview and on-canvas + interaction. + +Plug-ins: + + - Exported profile and data format strategy updated in several file + plug-ins. + + * When not saving a profile, we always export as sRGB data, as most + viewers would not display the image properly otherwise. + * When saving a profile: + * If a profile was manually assigned, we always export to the + assigned format, hence pixel data is converted accordingly, + whatever the work format. + * If no profile was assigned: + * If the export format support high-bit depth, we export the + work format as-is. + * If the export format is 8-bit max, we convert the work + format to sRGB, except if the work format is 8-bit linear. + + The following plug-ins were updated: JPEG, PNG, TIFF and WebP. + + - TIFF plug-in now supports layer export. + - Add accelerator on "Save color _profile" item in JPEG export so + that all items in the dialog have keyboard accelerators. + - Add a "Save color profile" checkbox in WebP export and remove the + "Advanced Options" expander (all metadata and profile writing + options are now directly visible). + - Process cases of non-conformant TIFF file with extra channels + while ExtraSamples is not set by assuming the first extra channel + is a non-premultiplied alpha channel and outputting a warning. In + the future, this should be updated further by a dialog asking what + to do with the non-defined dialog (consider as premultiplied or + non-premultiplied alpha channel, or just save as extra channels). + +Tools: + + - Add input/output spin-buttons to the Curves tool, which allow + setting the selected point's coordinates numerically. When the image + precision is greater than 8-bpc, use a 0.00-100.00 range for the + point-coordinate spin-buttons instead of a 0-255 range. + - In the Curves tool, allow changing the curve's point types (cf. new + curve corner points in Core section). Corner points are displayed + with a diamond shape instead of a circle. + - Free Select tool now creates a selection as soon as the polygon is + closed. This selection is updated when the polygon, or the relevant + tool-options, change, similarly to GimpRectangleSelectTool. + - Derive GimpEraser from GimpPaintbrush, instead of directly from + GimpBrushCore. + This allows GimpEraser to reuse the paint-buffer content across + dabs, improving performance. + - Allow moving an intersecting pair of guides with the Move tool. + +User interface: + + - In GimpCurveView, when dragging an existing curve point, don't + immediately move the point to the cursor position upon button + press, but rather move it relative to its current position as the + cursor moves. This allows selecting a point without moving it, and + adjusting its position more easily. + - when the cursor hovers above a point in GimpCurveView, or when + dragging a point, have the coordinate indicator show the point's + position, rather than the cursor's. + - In GimpCurveView, when holding down Ctrl while adding/dragging a + point, snap the y-coordinate to the original curve (at the start + of the drag). This is particularly useful for adding points along + the curve. + - In GimpDashboard, don't show legend for groups with no meter. + - Add a tile-alloc-total variable to the dashboard's memory and misc + groups, showing the total amount of memory used by the tile + allocator. + - Add a "Save Keyboard Shortcuts Now" button to the Configure + Keyboard Shortcuts dialog. + +Installers: + + - Windows: enable InnoSetup "unofficial" translations. Otherwise we + had a bunch of wasted work from our translators of several + languages whose translations were never used in the installer. + +Translations: + + - 12 translations were updated: Catalan, Chinese, French, German, + Hungarian, Indonesian, Italian, Polish, Russian, Spanish, Swedish + and Turkish. + + +Overview of Changes from GIMP 2.10.8 to GIMP 2.10.10 +==================================================== + +Core: + + - Add gimp-scratch allocator, a fast memory allocator (on the order of + magnitude of alloca()), suitable for small (up to a few megabytes), + short-lived (usually, bound to the current stack-frame) allocations. + Unlike alloca(), gimp-scratch doesn't use the stack, and is therefore + safer, and will also serve bigger requests, by falling-back to malloc(). + - In gimp_drawable_transform_buffer_affine(), avoid modifying the + clipping mode when transforming layer masks, since this function + is used (among other things) to transform layer masks together with + their layer, in which case they should use the same clipping mode + as the layer. This fixes a regression introduced by commit 2ae823ba, + causing layer masks to be transformed with a mismatched clipping mode + during layer transforms, leading to discrepancies between the + transformed layer and the transformed mask. + - Moved swap/cache and temporary files out the GIMP user config dir and + added new config file substitutions ${gimp_cache_dir} and + ${gimp_temp_dir}. + - Pass the GEGL tile-cache size, swap path, and thread-count to plug-ins + as part of their config, and have libgimp set the plug-in's GeglConfig + accordingly upon initialization. + - Layer groups are now rendered in bigger chunks rather than tile-by-tile + (which used to pretty much eliminate multithreading for groups), which + improves the rendering speed. + - Make saving/exporting files more robust to errors. In particular if + an error occurs during the process (be it a bug, a memory error, or + anything else), GIMP won't overwrite anymore any existing file with + incomplete contents, so that you won't end up with no valid files at + all. + - Fix a regression on support of various graphics tablet. + - Remove the "Edit -> Fade..." feature: it makes GIMP use two buffers + instead of one (east into system resources), it's broken in 2.10, and + we can make the UX better for filters. + - New generic canvas modifier 'Alt + middle click' allowing to pick + layers by clicking on pixels. The available layers will be looped + through (starting from the upper one) while Alt key is hold and the + picked layer name will be temporarily displayed in the status bar. + - When clearing a channel, do nothing if the channel is already empty; + otherwise, align the cleared rectangle to the channel buffer's tile + grid, so that all affected tiles are dropped, rather than zeroed. + Furthermore, only update the affected region of the channel. + - Brush and pattern saving logics has been moved to core code (instead + of plug-in). + - Clipboard brushes and pattern can now be duplicated. + - Parametric brushes are now 32-bit float to avoid posterization on + large brushes. + Note: raster brushes are still 8-bit and plug-ins only have access + to 8-bit versions of high-precision brushes/patterns. New API will + be required to handle high-precision data. + - On-canvas preview while editing a color in the colormap of an + indexed image. + +User interface: + + - Enabled HiDPI/Retina support for the GTK2/OSX build, fixes blurry icons. + - Add a tooltip to the "better compression" checkbox in save dialog to + make it clearer it does not mean that the file size is necessarily + smaller in every cases. In particular some best/worst case are + possible when an algorithm less efficient in general may end up + better on a particular image. + - Add basic support for cursors with a scale factor of 2 for HiDPI + (artwork to be updated). + - Foreground and background color icons, as well as color history will + now display out-of-gamut warning on indexed images for colors + outside of the palette, as well as on grayscale images, for non-gray + colors. + - Pack color picker and hexadecimal entry on same line in Color dock. + - Add an "Open as Image" button to the brushes dialog. + +Usability: + + - Attempting to transform locked layers or paint on them now results in + blinking around the status bar (where the warning message is displayed) + and around the toolbar where lock toggles are. The same applies to + attempting to move a selection where there is none — GIMP will blink + around the toolbar where the moving target (layer, selection, path) + is chosen. + - GIMP now allows selecting default export file type for new projects. + The choice is limited to PNG, JPEG, WebP, PSD, ORA, TIFF, BMP. + - GimpSpinScale widget now has an optional feature to constrain the + value to integer when dragging with a pointer (even if the scale + allows for fractional numbers), set with new function + gimp_spin_scale_set_constrain_drag(). + This is useful for settings where fractional numbers are technically + possible, yet most common use case are with integers (such as pixel + sizes, angles in degrees, etc.) so you want the easy interface to be + constrained. Fractional numbers are still settable, for instance by + keyboard edit; and arrow incrementation won't drop fraction parts. + This is currently only activated for brush options in paint tools. + +Tools: + + - In scale tool, scale around center even when using numeric input. + - New algorithm in the Bucket Fill tool when selecting the affected + area "Fill by line art detection", based off the G'Mic algorithm for + "smart colorization": https://hal.archives-ouvertes.fr/hal-01891876 + In a few words, it identifies painted pixels (either based on + grayscale or opacity values) and tries to close line arts to allow + filling even with not perfectly closed zones; the second step of the + algorithm will flood the colors under line art pixels to prevent + "holes" in the filling. + It is possible to control a max size (in pixels) for the flooding, + as well as max length of closing segments and splines. + - The Bucket Fill tool got new interaction allowing to hold the click + and move the mouse to fill based on several seed zones (for "Fill + by line art detection" as well as "Fill similar colors"). You can + now cancel the fill in progress with right click as in other tools. + - The Bucket Fill tool now allows color picking with ctrl-click, same + as every painting tool. It will pick either the foreground or + background color depending on the selected Fill Type. The ctrl-alt + modifier combination is also possible to pick the non-Fill Type + color. + - In the Bucket Fill tool, the Alt modifier will now switch to + "FG color fill" when "Pattern fill" was set (instead of doing + nothing). + - In the Unified Transform tool, default to preserving aspect ratio + when scaling up or down. + - In the Healing tool, "Sample merged" now also work for the target + pixels, allowing to draw in empty layers. + - Selection by color is now parallelized, hence improving speed of the + Select by Color tool (and any other processing which may share this + piece of code now or in the future). + - Add "Constrain handles" and "Around center" options to the + perspective-transform tool's GUI, which are similar to the + corresponding options of the unified-transform tool. + - Improve color picking on indexed image to always select an indexed + color corresponding to the picked pixel in the colormap. + +Plug-ins: + + - file-pdf-save GUI now clearly indicates the order the layers will be + used to make multi-page PDFs. + - Add DDS loading/exporting plug-in originally developed by Shawn Kirst + and Arne Reuter. + - Rename the Guillotine plug-in to Slice Using Guides. + - Add a new option saving a color profile when exporting PNG, JPEG, TIFF. + Always save it when exporting to PSD. + - Remove the "Advanced" expanders from the PNG and TIFF export dialogs. + - Full rewrite of the Spyrogimp plug-in with much more options and + better interaction. + - Indexed TIFF with alpha channel now supported. + +Filters: + + - Add on-canvas GUI (simple lines) for circular, linear, and zoom motion + blur. + +Help: + + - Link to the bugtracker directly from the Help menu, also link to the + wiki and the roadmap. Remove the link to currently disabled + registry.gimp.org. + +Installers: + + - Windows: proper fix for libthai to stop GIMP from crashing in the + Thai locale. + +Translations: + + - Czech, Danish, French, Italian, Japanese, Marathi, Polish, Russian, + Spanish, Swedish, Ukrainian. + +Build: + + - Bumping GTK+ dependency to the micro update GTK+ 2.24.32 to handle + several bugs on Windows (broken shortcuts on non-latin layouts and + broken vector icons). + + +Overview of Changes from GIMP 2.10.6 to GIMP 2.10.8 +=================================================== + +Core: + + - Use adaptive chunk size in GimpProjection when rendering the + projection asynchronously, rather than using a fixed chunk size. + This provides a better trade-off between throughput and + responsiveness dynamically, based on how fast the processing is. + - Add xyY color space to the color spaces for sampling colors. + +Tools: + + - In all selection tools, show error on attempt to + subtract-from/intersect-with empty selection. + - Fix text along path not working with vertical text. + - Fix Text tool's frame position when undoing a move operation. + - Streamline Text tool's drawing blocking/unblocking logic. + - When moving a text layer using the text tool (through alt+drag), + don't change the layer's box mode to "fixed", which is unnecessary, + since the layer's size isn't affected. + - Transform and deformation operations now maintain color for fully + transparent pixels, making unerase and curves manipulation of alpha + channel more reliable. + - All transform tools now apply changes when you save or export/overwrite + an image without pressing Enter first to confirm changes. + - Heal, Dodge/Burn, Smudge, and Convolve tools now adjust the processed + buffer and mask_buffer regions according to the changes made to the + application region, as calculated by intersecting it with the + drawable and mask extents. This fixes wrong application position + when painting on a drawable whose origin is above/to the left of the + image's origin, and there's a selection active. + - New type of gradient interpolation called 'Step' for making multi-color + hard-edge gradient fills. + +Plug-ins: + + - Port all plug-ins to the new iterator API in GEGL. + - Improve automatic detection of HEIC/HEIF files. + - Improve RawTherapee discovery by looking up registry key (should + become useful with RawTherapee 5.5 and more). + +Usability and UI: + + - Compatibility information in the Save dialog is now more understandable. + The minimum GIMP version for the XCF file is always written down when it + is GIMP 2.8 or over. The list of features warranting the minimum version + is now listed in an expander container rather than as tooltip, which + makes it more discoverable. The warning on compression is now displayed + as its own text under the checkbox and not as additional text to the + minimum GIMP version label. + - In all themes, fix the color of selected text, while editing a tree-view's + item text (such as when renaming a layer), by overriding tree-view + specific styling with the global text-entry style, for nested text entries + inside tree-views. The text would previously use the same color as the + selection background, making it unreadable. + - Add option in the Windows menu to hide the image tab bar. + +CLI: + + - New self-explanatory --enable-win32-debug-console CLI option + +Debugging: + + - New GimpBacktrace API provides an interface for creating and + traversing multi-threaded backtraces, as well as querying symbol + information. Backends are available for Linux and Windows. + - Performance log recording now available in the Dashboard dock. + The log contains a series of samples of the dashboard variables, + as well as the full program backtrace, when available. As such, + it essentially acts as a built-in profiler, which allows us to + correlate program execution with the information available + through the Dashboard. + - New performance-log-expand.py tool decodes a delta-encoded + performance log by expanding the deltas, producing a log where + each sample (and other relevant elements) contain complete + information. The structure of expanded logs is identical to that + of delta-encoded logs, the expanded log simply has no deltas. + - New performance-log-resolve.py tool resolves symbol information + in backtraces. The logs produced by GIMP only specify the program + counter at each stack frame, providing an address-map to map + program-counter addresses to actual symbols separately. This tool + looks up each program-counter address in the address map, + incorporating the relevant symbol information directly into the + backtrace. + - New performance-log-deduce.py tool that statistically deduces the + correct thread states based on backtrace address frequency, fixing + local inaccuracies. + - New performance-log-viewer.py tool that is a viewer for GIMP + performance logs, with a sample-selection area at the top and an + information area at the bottom. The sample-selection area visualizes + the sampled variables and markers using a simultaneous set of plots, + and displays the currently selected samples. The information area + shows global information stored in the log, as well as information + specific to the currently selected samples, including variable listing + and statistics, full backtrace, and profile/call-graph information. + +Translations: + + - Updated translations: Danish, Dutch, Finnish, German, Hungarian, + Italian, Marathi, Polish, Portuguese (Brazil), Russian, Spanish, + Swedish, Ukrainian. + + +Overview of Changes from GIMP 2.10.4 to GIMP 2.10.6 +=================================================== + +Core: + + - Render drawable previews asynchronously. + - Merge the file view filter and file format lists in GimpFileDialog. + The presence of 2 lists was very confusing. + - DLL search priority is now updated before running a plug-in on + Windows, depending on the executable bitness. This gets rid of one + of the last remnant of DLL hell in GIMP, which was when running + 32-bit plug-ins from a 64-bit build of GIMP. + +Filters: + + - New "Little Planet" (gegl:stereographic-projection) filter. + - New "Long Shadow" (gegl:long-shadow) filter. + +Tools: + + - Halt the Measure tool after straightening. + - Add an "orientation" option to the measure tool, corresponding to + the "orientation" property of GimpToolCompass (i.e., it controls the + orientation against which the angle is measured, when not in 3- + point mode.) The orientation is "auto" by default, so that the + angle is always <= 45 deg. Note that the "orientation" option + affects the tool's "straighten" function, so that the layer is + rotated toward the current orientation. + - Text layers can now represent vertical texts, with 4 variants: + left-to-right and right-to-left lines, and forcing all characters to + be upright or following Unicode's vertical orientation property. + See also: + * https://www.unicode.org/reports/tr50/ + * http://www.unicode.org/Public/UCD/latest/ucd/VerticalOrientation.txt + +User Interface: + + - The Dashboard dockable dialog now has an "async" field to the + dashboard's "misc" group, showing the number of async operations + currently in the "running" state. + - New Preferences option to enable/disable layer-group previews, since + these can get quite time-expensive. + +Translations: + + - New language: Marathi + - 12 translations were updated: Brazilian Portuguese, Dutch, French, + German, Greek, Italian, Latvian, Polish, Romanian, Slovenian, + Spanish, Swedish. + +Build: + + - Add --with-win32-32bit-dll-folder configuration option to override + the folder where 32-bit versions of DLL will be installed (default: + 32/bin/). + - Install all plug-ins in their own directories. Unlike on master, + this is not mandatory to do so, but it would protect our core + plug-ins against any DLL installed directly under plug-ins/ by + third-party plug-ins (cf. Windows DLL hell). + + +Overview of Changes from GIMP 2.10.2 to GIMP 2.10.4 +=================================================== + +Core: + + - Remove gimp_display_shell_draw_background() and all clipping hacks + for drawing the canvas background. This optimizes away one entire + step of drawing of image size, for each expose. + - Font loading does not block startup anymore. Only consequence is + that the Text tool may not be usable immediately if fonts are not + fully loaded yet (and will output an appropriate error if you do + so). All non-text related activities can be performed right away. + - Change of the URL from bugzilla to gitlab where appropriate. + - New tool option manager to better keep track of user context and + paint options in a consistent manner. + +User Interface: + + - The Dashboard dockable dialog now has a 'Memory' group that shows + memory-usage information: the currently used memory size, the + available physical memory size, and the total physical memory + size. It can also show the tile-cache size, for comparison + against the other memory stats. Note that the upper-bound of the + meter is the physical memory size, so the memory usage may be over + 100% when GIMP uses the swap. + - The Dashboard dockable dialog now has "read" and "written" fields in + the dashboard swap group, which report the total amount of data + read-from/written-to the tile swap, respetively. Additionally, the + swap busy indicator (used as the meter's LED) has been improved, + so that it's active whenever data has been read-from/written-to + the swap during the last sampling interval, rather than at the + point of sampling. + - Fonts can now be tagged. The user interface is the same as for + brushes, patterns etc. + - Some icons fixed: larger spacing between broken chains and + gimp-tool-ellipse-select made symmetrical. + +Usability: + + - When a plug-in cannot be applied to an image because of mismatch + in image types (e.g. layer has no alpha or image is greyscale), + GIMP now displays a message listing supported image types for this + plug-in. + +Tools: + + - The Measurement tool now has an "Auto straighten" option allowing + to rotate the active drawable (layer, channel…) so that the + measurement line is used as horizon. As other transform tools, the + feature will work on linked drawables as well. + - The Smudge tool now paints correctly on images with a color + profile other than the GIMP's built-in one. + +Build: + + - Installer: set compatibility options to run Python plugins in + HiDPI-aware mode. + - Put back compatibility DLLs for really old plugins. + - Install binary tool `gimp-test-clipboard` on the system to allow + people to help us debug clipboard bugs. + - --enable-bundled-mypaint-brushes renamed + --enable-relocatable-bundle and also make WMF fonts looked up on + the runtime prefix of GIMP (instead of the build-time path) when + this build option was set. + +Plug-ins: + + - gimptool-2.0 binary now accepts source files with non-standard + extensions if it can try to guess appropriate language from the + compiler being used. It will also properly quote arguments for + shell usage. + - Run explicitly Python 2 as Python plug-in interpreter to prevent + breakage on systems where Python 3 is the default. + - raw_input()'s argument in Python console is now optional, and + input() support has been added. + +File Formats: + + - The PSD loader now provides an option to load "merged", + pre-composited version of the images that becomes available when a + PSD file was saved with "Maximize Compatibility" option enabled in + Photoshop. This is useful when loading PSD files that use features + that GIMP doesn't currently support, and therefore can't render + correctly, such as adjustment layers. When loading the merged + image version, we avoid loading certain additional data from the + file, such as channels, paths, and guides, while still loading + metadata. This option is currently exposed as an additional file + type ("Photoshop image (merged)"), which has to be explicitly + selected from the file-type list when opening the image. + - Embedding GIMP's built-in sRGB color profile to exported files is + now optional. The default choice can be set in the Preferences + dialog. + +Translations: + + - Updated translations: Catalan, Czech, Danish, Dutch, Finnish, + Greek, Hungarian, Italian, Latvian, Polish, Romanian, Russian, + Spanish, Swedish, Ukrainian. + + +Overview of Changes from GIMP 2.10.0 to GIMP 2.10.2 +=================================================== + +Core: + + - Discard fonts which fail to load and popup an info dialog to allow + people debug their fonts. + - New API to suppress updates in UI until plug-ins are done + introducing changes. + - New API to calculate histograms in separate threads, with possible further + extension to handle similar cases elsewhere in GIMP. + - Tool options are now properly saved and reloaded per-device at + startup. + +Plug-ins: + + - New plug-in for importing and exporting HEIF images. + - Enable visibility of rasterized vector layer from PSD. + - Single-window screenshots in Windows fixed to correctly snap a + window even when it is partly off-screen or covered by another + window or when display scaling is not set to 100%. + +Filters: + + - New Spherize filter to wrap an image around a spherical cap + - New Recursive Transform filter to create Droste effect. + +Usability: + + - Warn users, when alpha-only painting has no effect. E.g. when target + drawable doesn't have an alpha channel, or the alpha channel is locked. + - Make the splash texts dynamic, so they are larger on larger splashes. + - Mention pressing Enter to complete Foreground selection in the status bar. + - Make sure that clicking outside any selection prevents Rectangle Select + and Ellipse Select tools from creating empty selections. + - Improve mouse wheel zooming behavior to keep the same point + centered under the pointer even if the image is completely visible + in the canvas. + - Add "View -> Center Image in Window" (Shift+J) as a quick way to + center the image at any zoom level. + +Translations: + + - Updated translations: Catalan, Danish, Dutch, French, German, Greek, + Hungarian, Icelandic, Italian, Latvian, Polish, Russian, Spanish, + Swedish, Ukrainian. + - New translation of Windows installer: Chinese (Taiwan) + +Build: + + - Add a --with-bug-report-url configure option allowing packagers to + set the address of their own bug tracker. This address will be the + one opened by the debug dialog for reporting bugs. + - Add a flatpak manifest for the gtk3-port branch. + - Remove the possibility to disable script-fu. + - Add a --with-icc-directory configure option to customize the color + profile directory. By default, it is set to the common path + /usr/share/color/icc. + +Documentation: + + - Updating the description of the XCF format "devel-docs/xcf.txt", for + third-party readers wishing to support GIMP 2.10 XCF files. + - Add documentation skeletons for all enums in libgimpbase/, there is + much room for improvement. |
