+Inkscape 1.0.2
+------------
+
+Released on **2021-01-17**
+
+Release highlights
+------------------
+
+This is a bugfix release:
+
+- More granular controls for canvas zooming and rotation
+- Fixes extensions popping up when a clipboard manager was used
+- Several crashes fixed
+
+
+
+
+
+Inkscape 1.0.1
+------------
+
+Released on **2020-09-07**.
+
+Release highlights
+------------------
+
+- Selectors/CSS dialog is now available
+- Experimental color-managed PDF export through Scribus
+- Many crash fixes and bugs fixed
+
+
+
+### Selectors and CSS dialog
+
+The Selectors and CSS dialog that was hidden and labelled as 'experimental' in
+Inkscape 1.0 is now available from the Object menu in 1.0.1. This new dialog
+allows users to edit a CSS stylesheet for the document and also to select all
+objects with a certain CSS selector, thus providing a replacement for the
+Selection Sets dialog, that had to be removed for Inkscape 1.0.
+
+### Scribus PDF export
+
+An experimental PDF export extensions was added that uses Scribus 1.5.5+ if it
+can be found in the path. You'll need to use a color profile in the SVG file
+and make sure to double-check the exported image, as there are many SVG
+features not supported by Scribus.

+
+General: Application
+--------------------
+
+### Performance
+
+Lots of small performance improvements in various areas combine to make
+Inkscape run smoother than before:
+
+-   Accelerated breaking apart of paths and Boolean operations (by
+    disabling intermittent canvas rendering during these operations).
+-   Accelerated "deselect" speed (by improving internal data structure
+    algorithms).
+-   Faster grouping and ungrouping of groups with a large number of
+    objects
+-   Speed boost to operations on large sets of objects in the Objects
+    dialog (Issue [\#392](https://gitlab.com/inkscape/inbox/-/issues/392))
+-   Faster lookup of attributes (MR
+    [\#448](https://gitlab.com/inkscape/inkscape/-/merge_requests/448))
+
+### Mac Application
+
+Inkscape is now a first-rate native macOS application, and no longer
+requires XQuartz to operate. The minimum required operating system
+version is OS X El Capitan 10.11.
+
+It has a standard Mac-style menu bar (rather than a menu bar within the
+window). Keyboard shortcuts now use the command (<kbd>⌘</kbd>) key
+rather than the control key. Retina display screen resolution is now
+supported. The build is now cleanly 64-bit, a prerequisite for macOS
+Catalina 10.15 and beyond. It comes bundled with Python 3 to power
+Inkscape extensions.
+
+General User Interface
+----------------------
+
+### Modernized GUI Toolkit
+
+The user interface has been changed to utilize a more recent version of
+GTK+ (GTK+ 3). This is a collection of user interface building blocks
+that Inkscape uses to draw the user interface on the screen. This new
+version brings many improvements, especially for users of HiDPI (high
+resolution) screens.
+
+Bringing the newer GTK+ toolkit to Inkscape has been an eagerly
+anticipated goal for a long time. It has taken much effort by the team
+involved and it was a focus point of the [Boston
+Hackfest](https://inkscape.org/en/news/2018/05/22/2018-boston-inkscape-hackfest/).
+
+### Window position / size / behavior
+
+Improvements and fixes to the code for handling/restoring window size
+and position
+[1](https://gitlab.com/inkscape/inkscape/-/merge_requests/180) were made.
+The window manager handles most of the jobs now, which should make it
+much more robust. If you still encounter problems with this, please
+report those [to our bug tracker](https://inkscape.org/report).
+
+The dialog opacity options have been removed, because they were causing
+crashes that could not be fixed otherwise.
+
+### High Resolution Screens
+
+Inkscape now supports HiDPI (high resolution) screens natively. This
+means that icons and node handles will no longer be tiny on monitors
+with large pixel dimensions, and the canvas will no longer look blurry.
+
+### Tool box
+
+The tools have been reordered and grouped into more logical groups.
+Groups from top to bottom:
+
+-   Edit tools
+-   Create Shapes
+-   Create Shapes from scratch
+-   Color Editing
+-   Other tools
+-   Canvas tools.
+
+Users can customize the order of the tools by putting a customized
+version of the file `inkscape/share/ui/toolbar-tool.ui` into a folder
+named `ui` in their Inkscape user configuration folder, if they prefer a
+different order.
+
+### Improved number entry fields
+
+Many numeric entry fields no longer change their value when scrolling
+while the mouse is hovering over them. They now need to be selected
+(clicked into). Then scrolling will change the value as previously. This
+change was made, because scrolling docked dialogs easily led to
+accidental change of values.
+
+Additionally, **<kbd>Ctrl + Scroll</kbd>** on a selected numeric entry
+field will now change the value in larger steps.
+
+Canvas
+------
+
+### Y-Axis Inversion
+
+During the [Inkscape Hackfest in
+Kiel](https://inkscape.org/en/news/2018/09/20/inkscape-hackfest-kiel-2018-what-happened/),
+a significant change by Thomas Holder was integrated into the Inkscape
+codebase. It sets the origin of the document to the top left corner of
+the page. This finally makes the coordinates that a user can see in the
+interface match the ones that are saved in the SVG data (unit
+conversions/transformations may be required), and makes working in
+Inkscape more comfortable for people who are used to this more standard
+behavior. The old behavior can be reactivated in the preferences, at
+`Edit → Preferences → Interface` (disable 'Origin in upper left with
+y-axis pointing down').
+
+### Canvas Rotation
+
+With **<kbd>Ctrl + Shift + Scroll wheel</kbd>** or **<kbd>Ctrl + Scroll
+wheel dragging</kbd>** the drawing area can be rotated and viewed from
+different angles. In the bottom right corner of the window, the viewing
+angle can be entered manually. **<kbd>Right-click</kbd>** to select
+between a set of preset values. You can also reset canvas rotation in
+`View → Canvas orientation → Reset Rotation`. Keyboard shortcuts for
+clockwise/counter-clockwise/no rotation can be set in the preferences.
+
+### Canvas Mirroring
+
+The canvas can now be flipped, to ensure that the drawing does not lean
+to one side, and looks good either way. The vertical/horizontal flipping
+is available from the menu
+`View → Canvas orientation → Flip horizontally / Flip vertically`.
+Keyboard shortcuts for flipping the canvas can be set in the preferences
+(`Edit → Preferences → Interface → Keyboard shortcuts`).
+
+### Pinch-to-zoom
+
+On supported hardware (trackpad, touchpad, multi-touch screen), the
+canvas can be zoomed with the two-finger pinch gesture.
+
+### Duplicate Guides
+
+A new option for duplicating guides was added to the 'Guideline' dialog
+(access by double-clicking on a guide line). This new feature, when used
+before the 'relative change' option (dialog needs to be opened once for
+each step), makes it easier to create guides that are offset by a
+certain distance / angle from an existing guide.
+
+### Context menu
+
+The menu that appears after a right-click on the canvas has been
+extended with the following items, which makes locking/unlocking and
+hiding/unhiding individual objects much more comfortable:
+
+-   Hide selected objects
+-   Unhide objects below (the mouse cursor)
+-   Lock selected objects
+-   Unlock objects below (the mouse cursor)
+
+### Snapping
+
+-   In `Edit → Preferences → Behavior → Snapping`, a new option was
+    added to **disable snapping** in new documents or files that are
+    opened with Inkscape for the first time.
+
+View
+----
+
+### Center view on page
+
+You can now center the view on the page, without changing the zoom
+level.
+
+This function is available via:
+
+-   `View → Zoom`
+-   the Zoom tool's tool controls bar
+-   Keyboard shortcut **<kbd>Ctrl + 4</kbd>**
+
+### Split View Mode
+
+The new Split View Mode features a draggable separator that becomes
+visible as soon as the Split view mode has been activated. On one side
+of the separator, the canvas will look just like before, while on the
+other side, everything will be displayed in outline mode, and objects
+can more easily be grabbed with the mouse or edited with the node tool.
+
+It can be moved on the canvas by grabbing either the separation line or
+the central handle. The sides can be switched by clicking on one of the
+little arrows on the handle.
+
+Activate it with one of:
+
+-   `View → Split View Mode`
+-   **<kbd>Ctrl + 6</kbd>**
+
+To deativate the mode, either deactivate the checkbox in the menu again,
+use the keyboard shortcut a second time, or drag the separator off the
+canvas.
+
+### X-Ray Mode
+
+When the X-Ray mode is active, a circular area that shows objects on the
+canvas in outline mode will follow the mouse pointer. This makes editing
+complex drawings with many objects layered on top of one another much
+easier, and is especially useful when used with the node tool.
+
+Activate it with:
+
+-   `View → XRay Mode`
+-   <kbd>Alt + 6</kbd>
+
+The size of the X-Ray circle can be adjusted in
+`Edit → Preferences → Rendering → Rendering XRay radius`.
+
+To deactivate the mode, either deactivate the checkbox in the menu
+again, or use the keyboard shortcut a second time.
+
+### Visible Hairlines Display Mode
+
+This new display mode is available in the menu under
+`View → Display Mode → Visible Hairlines`. It ensures that all lines of
+nonzero width are visible (with a minimum visible line width),
+regardless of zoom level, while still drawing everything else normally.
+
+This is especially useful if you need to assign very small line widths
+for use with CNC machines like laser cutters and vinyl cutters which use
+hairlines to denote cut lines. In that case, you will still be able to
+see the lines, even when zoomed out.
+
+Paths
+-----
+
+### Changed behavior of Stroke to Path
+
+The 'Stroke to Path' command now not only converts the stroke of a shape
+to path, but effectively splits it into its components.
+
+In the case of applying it to a path that only has a stroke, the
+behavior is unchanged.
+
+For paths that don't only have a stroke, but also a fill and/or markers,
+the result will be a group consisting of:
+
+-   Stroke outline turned to path
+-   Fill (if there was one)
+-   A group of all markers (if applicable; one group per marker,
+    consisting of its outline and its fill turned into a path)
+
+### Unlinking Clones for Path Operations
+
+Clones and Symbols are now automatically unlinked, before a Boolean
+operation (union, difference, etc.), or one of the Path operations
+'Combine', 'Break apart', or 'Stroke to Path' is performed.
+
+A setting in the preferences at `Behavior → Clones → Unlink Clones`
+allows the User to disable the automatic unlinking.
+
+Tools
+-----
+
+### Bézier Tool
+
+The tool mode 'Create sequence of paraxial segments', which previously
+would only draw lines parallel to the x and y axis of the document, now
+supports arbitrary starting angles. After the first segment, all further
+angles will use the current angle ±90°. If you want your first segment
+to work as in previous versions, you need to press **<kbd>Ctrl</kbd>**
+after the first click. This will restrict your options to (by default)
+15° steps.
+
+### Calligraphy Tool
+
+A new option to add dots has been added to the tool. Click in place
+without moving the mouse to create a dot, **<kbd>Shift + Click</kbd>**
+to create a larger dot *\[Known issues:
+[inbox\#2368](https://gitlab.com/inkscape/inbox/-/issues/2368),
+[inbox\#2342](https://gitlab.com/inkscape/inbox/-/issues/2342)\]*.
+
+### Circle Tool
+
+The circle tool can now also create closed ("filleted") circle shapes
+(closed arcs) with the click of a button.
+
+### Eraser
+
+-   Added option to control eraser width with a pressure sensitive input
+    device.
+-   Added thinning, caps, and tremor options (as used for calligraphy
+    tool).
+-   New option to erase as clip, which allows the User to
+    non-destructively erase (parts of) various types of elements,
+    including raster images and clones.
+
+### Measurement Tool
+
+Hovering over a path with the tool now displays the length, height,
+width, and position of the path. If you hover over a group, it will show
+the width, height, and position of the group. Holding
+**<kbd>Shift</kbd>** switches to showing info about the constituents of
+the group.
+
+The tool also has a new option to only measure selected objects when
+using click-and-drag.
+
+### Pencil Tool
+
+#### PowerPencil
+
+Pressure sensitivity can now be enabled for the Pencil tool. This
+feature makes use of the PowerStroke Live Path Effect (LPE).
+
+New settings for the tool are available for tweaking the behavior of the
+PowerStroke LPE when it is being created with the Pencil tool (and a
+graphics tablet/stylus):
+
+-   **Use pressure input** (in the tool controls bar): activates the
+    PowerStroke feature, if a pressure sensitive device is available.
+-   **Min/Max** (in the tool controls bar): determines the minimal and
+    maximal stroke width (0–100%). This does not change the number of
+    available pressure levels, but spreads them out in the available
+    line width interval.
+-   **Caps** (in the tool controls bar): choose between the options
+    'butt', 'square', 'round', 'peak' and 'zero width' for the end caps
+    of the stroke.
+-   Additionally, the PowerStroke LPE itself has been improved, to
+    better work when used in this new way, see [the section about LPE
+    updates](#powerstroke-lpe-improvements).
+
+### Selection Tool
+
+#### On-Canvas Alignment
+
+When the option "Enable on-canvas alignment" is active in the "Align and
+Distribute" dialog, a new set of handles will appear on canvas when an
+object is clicked three times (first click: scale handles, second click:
+rotation/skew handles).
+
+The handles can be used to align the selected objects relative to the
+area of the current selection.
+
+-   **<kbd>Shift + click</kbd>** on the outer handles aligns on the
+    outside of the selection area.
+-   Clicking on the central handle will align the selected objects on
+    the horizontal axis. On **<kbd>Shift + click</kbd>** objects will be
+    aligned on the vertical axis.
+-   With **<kbd>Ctrl + Shift </kbd>** the whole selection can be aligned
+    to its outer boundaries / corners as a group (i.e. it is moved by
+    its own `width` and / or `height`).
+
+### Text Tool
+
+#### More Compact Tool Controls Bar
+
+-   Some control buttons that have been mutually exclusive (e.g.
+    right-aligned, left-aligned, justified) have been combined into
+    drop-down lists, so they now take up less space.
+-   Removed the 'Show style of outermost text element' button that made
+    settings confusing.
+
+#### Better Line Height Settings
+
+-   Line spacing settings got an overhaul and are now much easier to
+    use. Gone is the unwieldy `?` button; this is now handled by
+    selecting text on canvas.
+-   Setting line height works like this now:
+    -   For the whole text: click anywhere into the text without
+        selecting anything, then adjust the line height in the tool
+        controls bar.
+    -   For a specific line: select the text in that line, then adjust
+        the line height in the tool controls bar.
+    -   Set the global line height first, and the specific line heights
+        last. Changing global line height later will remove any
+        line-specific line-heights (even just changing the unit will
+        unset those ).
+    -   Line heights for single selected lines cannot go below the
+        height set globally.
+    -   If more than one line is selected, the line height in between
+        those lines can go below the line height set for the whole text.
+-   The line height settings work in all four text types.
+
+#### Improved Text Selection
+
+When clicking on a text object, any click within the whole area of a
+text line now selects the text with both selection and text tool
+(previously, clicking into the space between two letters did not select
+the text).
+
+#### Variable Font Support
+
+If Inkscape has been compiled with a Pango library version that is at
+least 1.41.1 (which is the case for the Windows and macOS versions, and
+for Ubuntu versions starting from 19.04), it comes with [ support for
+variable fonts](https://wiki.inkscape.org/wiki/index.php/Variable_Fonts_support) ([more info about how
+this looks](https://www.patreon.com/posts/font-variations-17644963)).
+These are fonts that do not come with different faces, but often with
+various sliding scales for different font properties, like 'boldness',
+or 'condensing', or even playful features.
+
+#### Basic Support for SVG in OpenType
+
+Some OpenType fonts with glyphs saved as SVG render now in Inkscape.
+
+#### Flow order
+
+With `Text → Flow into Frame`, text now flows into the selected frames
+in selection order (instead of reversed order previously).
+
+#### Browser-compatible flowed text
+
+**Flowed text** (created by clicking and dragging a text frame) in
+previous Inkscape versions was not compatible with browsers, and
+rendered as 'black boxes' in web browsers and other SVG viewers, or was
+just missing.
+
+The old flowed text can still be enabled by unchecking
+`Edit → Preferences → Tools → Text: Use SVG2 auto-flowed text`.
+
+Now, Inkscape offers to use **two new types of flowed text**, that have
+a compatible fallback for use with modern web browsers:
+
+1.  **SVG 2 text using the CSS `shape-inside` property:** This new
+    flowed text automatically **includes a fallback option** (in SVG
+    1.1), and will show up in web browsers and other software. This type
+    of text can be created by **clicking and dragging a box** on canvas,
+    **if the option 'Use SVG 2 auto-flowed text' is enabled** in the
+    Text tool's preferences. When the option is enabled, it will also be
+    used for `Text → Flow into frame`. Kerning and letter rotation do
+    not work with this type of text.
+2.  **SVG 2 text with `inline-size` property:** This is the new "Column
+    mode" of the text tool, that can be created by clicking on the
+    canvas, typing, and then dragging the diamond-shaped handle at the
+    end of the text to determine the width of the text. It creates
+    flowed text columns without a predetermined height. Note that this
+    text can be left-, center- or right-aligned, but that justification
+    is not possible. Kerning and letter rotation also do not work with
+    this type of text. These texts include an SVG 1.1 fallback, too. To
+    convert the text back to SVG 1.1 text, **<kbd>Ctrl-click</kbd>** on
+    the diamond (this will result in all the text being placed on a
+    single line).
+
+The fallback option can be disabled in
+`Edit → Preferences → Input/Output → SVG export: SVG 2: Insert SVG 1.1 fallback in text`.
+
+#### Overview of available text types
+
+#### SVG 2 Text Support in Detail
+
+Inkscape supports SVG 2 text (multi-line and text in a shape), both
+rendering and creating.
+
+There are several types of SVG 2 text:
+
+##### 1. Multi-line text via the CSS 'inline-size' property
+
+The CSS property `inline-size` defines the width (height) of a block of
+horizontal (vertical) text. Inkscape supports both rendering and
+generating multi-line text via this property. Flowed text using
+'inline-size' is not justifiable (it uses the 'text-anchor' property).
+This text type has an SVG 1.1 fallback, that is included by default.
+
+##### 2. Multi-line text via the CSS 'shape-inside' property
+
+The CSS property `shape-inside` allows placing text inside a shape.
+Inkscape supports this property in both rendering and creating. Inkscape
+also supports in rendering the CSS `shape-subtract`, `shape-margin`, and
+`shape-padding` properties.
+
+Multi-line text via the `shape-inside` property is a direct replacement
+for SVG 1.2 flowed text. SVG 1.2 never became a final W3C standard and
+only the Batik SVG renderer besides Inkscape provided any support for
+SVG 1.2 flowed text. SVG 2 is not yet a final W3C standard but SVG 2
+flowed text has one very important advantage over SVG 1.2 flowed text in
+that it is easy to structure the SVG 2 text such that it will be
+rendered (almost) correctly by an SVG 1.1 renderer. This means that
+browsers which do not support SVG 2 text will still render the text.
+
+##### 3. Multi-line text via the CSS 'white-space' property (only rendering)
+
+The CSS property
+['white-space'](https://developer.mozilla.org/en-US/docs/Web/CSS/white-space)
+controls how white space is handled. By default, SVG collapses all
+adjacent white-space including newlines into a single space. By setting
+the `white-space` value to `pre`, `pre-line`, or `pre-wrap`, Inkscape
+will respect newlines and generate multi-line text. At the moment, one
+must use the XML Editor dialog to change the `white-space` property
+value. (Supported by Firefox. No SVG 1.1 fallback created by Inkscape.)
+
+One disadvantage of using SVG 2 text is that it will not be editable as
+multi-line text in Inkscape 0.92 (it will still be editable as single
+lines of text).
+
+Clipping / Masking
+------------------
+
+Clip paths and masks now have an inverse mode in the menu, using the
+PowerClip and PowerMask LPEs.
+
+Filters
+-------
+
+The size of the filter region can now be adjusted by dragging on two new
+diamond-shaped nodes with the node tool. This is especially useful for
+blur filters, whose area has been affected by a transformation of the
+filtered object.
+
+Live Path Effects
+-----------------
+
+### General
+
+Live Path Effects received a major overhaul, with lots of improvements
+and new features. The main changes are:
+
+-   **New LPE selection dialog**: the LPE
+    list is now made available as a searchable dialog with an icon for
+    each path effect, and options to favorite, to switch between list
+    and tile view, to display info about the selected effect and to
+    apply it. Several additional, experimental path effects are
+    available after the corresponding switch has been activated.
+-   **Set default parameters**: default values for any LPE can be set in
+    the respective LPE's dialogue, when it is applied to an object
+
+(*Note: we have the 'multiple desktop preferences' problem here: If you
+have multiple Inkscape windows open, the last one will determine what
+will be saved to the preferences file, as preferences changes are only
+saved when Inkscape is closed, and the settings are only loaded from
+file when a new window is opened.*)
+
+-   **Clip and Mask**: improved handling
+-   **Fix multiple LPE BBox**: a problem with the size of the bounding
+    box when applying multiple LPEs to an object has been fixed.
+    Sometimes you need to add a intermediate LPE bounding box between.
+-   **Knots on shapes**: show edit knots in LPE shapes
+-   **Switch knots**: change the handles to the correct LPE handles when
+    one selects an LPE in the list of active LPEs for the selected
+    object.
+
+### New Live Path Effects
+
+#### Dashed Stroke LPE
+
+This new LPE creates uniformly dashed paths, optionally by subdividing
+the path's segments, or including dashes that are symmetrically wrapped
+around corners.
+
+[Demo Video](https://archive.org/details/dash-stroke-lpe)
+
+#### Ellipse from Points
+
+This new LPE creates an optimally fitted ellipse from a path's nodes.
+
+In contrast to the already existing LPE "Ellipse by 5 points", this LPE
+is more flexible (since, depending on the number of points available, it
+can fit both circles and ellipses) and has more features). Technical
+illustrators in particular can benefit from these features.
+
+See [LPE:\_Ellipse\_from\_Points](https://wiki.inkscape.org/wiki/index.php/LPE:_Ellipse_from_Points)
+for more documentation.
+
+#### Corners (Fillet/Chamfer) LPE
+
+This new LPE adds fillet and chamfer to paths. Also adds a new internal
+class that allows to handle extra info per node, the LPE itself is an
+example of use the new classes.
+
+[Demo video](https://www.youtube.com/watch?v=wJKzGhJULfc)
+
+#### Measure Segments LPE
+
+This new path effect adds DIN and custom style measuring lines to
+"straight" segments in a path.
+
+[Demo video](https://www.youtube.com/watch?v=ppgt2GPm1IY)
+
+#### Offset
+
+Use this to add an offset to your paths, shapes and groups. Compared
+with the 'Dynamic Offset' available from the menu, this allows you to:
+
+-   define the offset distance numerically and to choose the unit, e.g.
+    to offset an object by 3 mm.
+-   keep sharp corners sharp (or to make them round, or beveled, if you
+    want to), by using different methods for calculating the corners.
+-   same on-canvas control handle for changing the offset when using the
+    node tool
+
+#### Power Clip and Power Mask
+
+These two new LPEs can be applied to objects by choosing
+`Object → Clip → Set Inverse (LPE)` or
+`Object → Mask → Set Inverse (LPE)`.
+
+They can also be used to invert a clip that is already set on an object,
+by adding the LPE to that object via
+`Path → Path Effects → + → Power Clip / Power Mask`
+
+An Inversed Clip is cut out from the object it's applied to. With an
+Inversed Mask it's possible to modify only the parts of the object that
+are directly below the mask, and to leave the rest of the object
+unchanged (and visible).
+
+### New Experimental LPEs
+
+#### Angle Bisector
+
+Draws a line that halves the angle between the first three nodes of the
+path.
+
+#### Boolean Operation LPE
+
+The Boolean Operation LPE finally makes non-destructive boolean
+operations available in Inkscape. That way, two paths can be combined to
+a single shape, and both are still editable:
+
+1.  Start with two paths. Rectangles or other shapes are also okay.
+    Groups are not yet supported ([Issue
+    \#1352](https://gitlab.com/inkscape/inkscape/-/issues/1352)).
+2.  Copy the second path into the clipboard (`Edit → Copy`).
+3.  Select the first path and add the Boolean Operation LPE
+    (`Path → Path Effects → Add path effect (Plus) → Boolean operation`).
+4.  Link the second path to the LPE by clicking on
+    `Operand Path - Link to path in clipboard`.
+
+Available options:
+
+-   union
+-   symmetric difference
+-   intersection
+-   division
+-   difference
+-   cut
+
+#### Circle by 3 points
+
+Draws a circle whose circumference passes through the first three nodes
+of the path.
+
+#### Circle (by center and radius)
+
+Draws a circle where the first node of the path is the center, and the
+last node determines the radius.
+
+#### Extrude
+
+Extrudes the path, creating a face for each path segment.
+
+#### Line segment
+
+Draws a straight line that connects the first and last node of the path.
+
+#### Parallel
+
+Creates a draggable line that will always be parallel to a two-node
+path.
+
+#### Perpendicular Bisector
+
+Draws a perpendicular line in the middle of the (imaginary) line that
+connects the start and end nodes.
+
+#### Tangent to Curve
+
+Draws a tangent with variable length and an additional angle that can be
+moved along the path.
+
+### Improved LPEs
+
+#### BSPline and Spiro
+
+Improvements in Pen/Pencil mode. With **<kbd>Alt</kbd>**, you can move
+the previous node.
+
+#### Clone Original
+
+This path effect now allows various objects instead of only paths and is
+even more powerful.
+

+
+[Demo
+Video](https://ia601501.us.archive.org/34/items/00003303/0000-3303.ogv)
+
+#### Fill Between Many / Fill Between Strokes LPE
+
+New options added:
+
+-   Fuse coincident points
+-   Join subpaths: fill each path separately / connect all the fills
+-   Close: close the fill path that is created, so it can have a stroke
+    on all sides
+-   LPEs on linked: take the applied live path effects of the filled
+    paths into account (Fill Between Many only)
+
+#### Knot LPE
+
+New options added:
+
+-   Inverse: use the stroke width *of the other path* as basis for
+    calculating the gap length
+-   Both gaps: interrupt both paths at a crossing
+
+#### Mirror Symmetry and Rotate Copies LPE
+
+-   Split feature: This new feature allows custom styles for each part
+    of the resulting drawing without unlinking the LPE. [Demo
+    Video](https://www.youtube.com/watch?v=mIzrQ2lpzuw)
+-   The LPE rendering on the canvas now updates accordingly when there
+    are objects added or removed.
+
+#### PowerStroke LPE Improvements
+
+-   **Width scale** setting added: adjust the overall width of the
+    stroke after it has been drawn.
+-   **Closed paths**: PowerStroke now works much better on closed paths.
+
+Import / Export
+---------------
+
+### Linking and embedding SVG files
+
+On import of an SVG file, there is now a dialog that asks whether
+
+-   the user would like to link to the SVG file
+-   to embed it (base64 encoded) into an `<img>` tag,
+-   or if the objects in the SVG file should be imported into the
+    document (which was how Inkscape handled importing SVG files
+    previously).
+
+The dpi value for displaying embedded SVG files can be set in the import
+dialog or changed in the object properties dialog.
+
+This makes importing SVG files work (almost) the same as importing
+raster images.
+
+The 'Embed' and 'Extract' options in the context menu for linked SVG
+files work the same as they do for raster images. The 'Edit externally'
+option will open the linked SVG file with Inkscape per default. This
+setting can be changed in the preferences' 'Imported Images' section.
+
+The displaying of the dialog can be disabled by checking the 'Don’t ask
+me again' option.
+
+Linked and embedded SVG images are displayed as their raster
+representations, so they will become blurry when zoomed in too far.
+
+### Mesh Gradient Polyfill
+
+SVG files that include a mesh gradient now automatically include a
+Javascript polyfill that allows the mesh gradient to display correctly
+in web browsers.
+
+### SVG 1.1 compatibility
+
+Inkscape includes SVG 1.1 fallbacks for text by default (see [the
+section about text tool updates](#text-tool)).
+
+When exporting as SVG 1.1 explicitly, using the checkbox in the export
+dialog, some settings are available in
+`Edit → Preferences → Input/Output → SVG Export`, in order to allow for
+correct rendering of markers in other software.
+
+### Export PNG images
+
+The export dialog has received several new options which are available
+when you expand the 'Advanced' section.
+
+-   Enable interlacing (ADAM7): when loading images, they will be
+    displayed faster
+-   Bit depth: set the number of bits that code for the color of a
+    pixel, supports grayscale and up to 16-bit
+-   Compression type: choose strength of lossless compression
+-   pHYs dpi: force-set a dpi value for the image
+-   Antialiasing: choose type of anti-aliasing or disable it
+-   The option for "Cairo PNG" has been removed from the "Save as"
+    dialog, as it was often confused with the "Export PNG image" option,
+    but only supported a small subset of PNG rendering features.
+
+### PDF Export
+
+-   External links in the SVG file are now kept when the file is
+    exported to pdf (requires Cairo in version 1.15.4 or higher).
+-   Some Inkscape file metadata (<code>File → Document properties : Metadata</code>) are now exported to PDF (title, subject, creator, keywords).
+
+### (E)PS Export
+
+-   The title and copyright ('rights') info from the document's metadata
+    is now exported to (E)PS.
+
+### OpenClipart Import Removed
+
+The dialog and settings for importing images from OpenClipart have been
+removed due to the openclipart.org API being non-functional since
+mid-April 2019 with no information about a return date.
+
+Extensions
+----------
+
+### Extension dialogs
+
+Extension dialogs can now have clickable links, images, a better layout
+with separators and indentation, multiline text fields, file chooser
+fields and more. For detailed info for development see the [developer
+section](https://wiki.inkscape.org/wiki/index.php/Release_notes/1.0#For_extension_writers) above.
+
+### Export Layer Slices
+
+`Extensions → Export → Export Layer Slices`
+
+The new 'Export Layer Slices' extension allows you to export PNG
+"slices" from your image by creating a new layer and drawing rectangles
+to denote the area of the export.
+
+If you create a layer (default name "slices") with rectangles in it,
+this extension will export a PNG file for each rectangle into the
+directory with the name of the {rectangle ID}.png (use Object Properties
+to set this).
+
+If the export already exists, it will skip it and color the rectangle
+GREY. If the "Overwrite existing exports" checkbox is selected, and the
+file was previously generated, it will color the rectangle RED. For new
+exports that did not previously exist, the rectangle will be GREEN.
+
+If you want to create (square) icons at different sizes, select "Icon
+mode". Icon mode will create a square export for each dimension in
+"Sizes".
+
+### Frame
+
+`Extensions → Render → Frame`
+
+This new extension will add a rectangular frame with a specified stroke
+width, and specified stroke and fill colors to each object in the
+selection. Optionally, corners can be rounded, and the frame can be
+positioned inside or outside the selection. The result can be grouped
+with the frame, and the object can be clipped to the size of the frame
+(for further editing).
+
+### Hershey Text
+
+`Extensions → Text → Hershey Text`
+
+The "Hershey Text" extension, a utility for replacing text by
+stroke-based paths, has been rewritten. The most significant
+improvements are:
+
+-   The new version converts all or only the selected text objects in
+    place. This means that it is possible to convert text with
+    paragraphs and to convert multiple text objects at once.
+-   It now uses **SVG fonts**. This means that:
+    -   It is now possible to easily add and use **custom stroke
+        fonts**.
+    -   **Unicode characters** are now supported.
+    -   Stroke fonts now support **arbitrary curves** rather than only
+        straight segments.
+-   **Improved font selection** with basic international characters
+-   Automated **font-mapping**: each text will be converted to the
+    available Hershey font with the same font file name (e.g. 'Fancy
+    Font.svg') as the current font (e.g. 'Fancy Font'), if one is
+    available to the extension. The automated mapping overrides any
+    other Hershey font settings.
+-   An option to **generate font samples** in all available SVG fonts is
+    available.
+-   An **extensive help text** is built into the extension.
+-   Hershey Text is now located in the *Extensions → Text* sub-menu.
+
+
+### Interactive Mockup
+
+`Extensions → Web → Interactive Mockup`
+
+The new Interactive Mockup extension is intended for use by UI/UX
+designers. It can help to visualize mockups and create user flows to
+make interactive demos for approvals.
+
+To use it, select two or more objects: the first one(s) will be the
+active one (button, area, image, link…), and the last selected will be
+the element that should be displayed after activation.
+
+Apply the extension, then save as SVG and open it in a browser for
+demonstrating the mockup to potential users.
+
+`Extensions → Modify Path → Mesh → Meshgradient to Path / Path to Meshgradient`
+\[doesn't work: <https://gitlab.com/inkscape/extensions/-/issues/216>\]
+
+A set of two extensions that convert mesh gradient geometry to paths and
+back.
+
+
+`Extensions → Export → Plot`
+
+The new option 'Convert objects to paths' will take care of converting
+everything to a path non-destructively before the data is sent to the
+plotter. \[Known issue: [does not
+work](https://gitlab.com/inkscape/extensions/-/issues/211)\]
+
+`Extensions → Render → Barcode → QR Code`
+
+Options for choosing the shape of single QR code dots were added ([but
+do not work](https://gitlab.com/inkscape/extensions/-/issues/150)).
+
+
+Palettes
+--------
+
+New palettes:
+
+-   The **Munsell** palette
+-   the **Bootstrap 5** palette and
+-   the palette for the **new GNOME Human Interface Guidelines** (GNOME
+    HIG)
+
+have been added to Inkscape's set of stock palettes.
+
+Users can now also drag the `none` color field from the palette bar at
+the bottom onto objects to set their color to `none`.
+
+Templates
+---------
+
+-   The **Desktop** template has new options for 4k, 5k, and 8k screens.
+-   Some new page sizes were added to the **(Blank) Page** template.
+-   New: template for an **A4 3-fold roll flyer**
+-   New: template for **Envelope** with 2 standard envelope formats
+
+SVG and CSS
+-----------
+
+-   **Dashes**: Inkscape can now load and display files with dashes
+    and/or dash offsets defined in units other than the unitless user
+    unit (e.g. `%`, `mm`) correctly. There is no user interface for
+    editing these values currently, except for the XML editor. Values
+    for `stroke-dasharray` that are entered in other units (except for
+    `%`) will be converted to user units when the new values are set.
+
+
+-   **Blend modes** applied via Layers and Objects dialog no longer use
+    SVG filters, but CSS blend modes. These can be exported to PDF
+    without rasterization.
+
+
+-   **Hairlines** can now be rendered in Inkscape. There is currently no
+    user interface for adding them yet, though. Hairlines can be
+    specified by adding
+    `stroke-width:1px; stroke-width: -ink-hairline; vector-effect:non-scaling-stroke;`
+    into the <code>style</code> tag of the object via the XML editor or the Style dialog.
+    Hairlines will be exported to PNG correctly. Export to PDF requires
+    that the Cairo library that your Inkscape program was compiled with
+    contains the additional code from
+    <https://gitlab.freedesktop.org/cairo/cairo/merge_requests/21> (as
+    of April 29, 2020, there's no official Cairo version available yet
+    that contains the patch).

+
+### About
+
+`Help → About Inkscape`
+
+The Inkscape 1.0 About screen features the winning entry of the
+[Inkscape 1.0 About Screen
+Contest](https://inkscape.org/gallery/=about-screen-contest/contest-for-10/),
+["Island of
+Creativity"](https://inkscape.org/~bayubayu/%E2%98%85island-of-creativity)
+by [Bayu Rizaldhan
+Rayes](https://inkscape.org/news/2020/02/11/inkscape-brings-enjoyment-and-freedom-creativity/),
+and its layout has changed a little.
+
+### Arrange
+
+`Object → Arrange`
+
+The 'Polar coordinates' functionality now arranges objects clockwise (in
+selection order) around the circle/ellipse. This should better
+correspond to user expectations.
+
+### Document Properties
+
+-   When resizing the page, the page margin fields can now be
+    **locked**, so the same value will be used for all margins, but only
+    needs to be entered once.
+-   The guides panel now has controls to lock or unlock all guides,
+    create guides around the page, and delete all guides. These actions
+    also appear on the Edit menu, making it possible to assign custom
+    keyboard shortcuts.
+-   **Grids can now be aligned** to the corners, edge midpoints, or
+    centre of the page with a button click in the grids panel.
+-   Checkerboard patterns can now have a color (for updating the current
+    view, check and uncheck the box for the checkerboard background,
+    [Issue \#2561](https://gitlab.com/inkscape/inbox/-/issues/2561)).
+    This color will also be used as a (non-checkered) background for PNG
+    export.
+-   A set of new page formats for different Video resolutions (SD/PAL,
+    SD-Widescreen/PAL, SD/NTSC, SD-Widescreen/NTSC, HD 720p, HD 1080p,
+    DCI 2k (Full Frame), UHD 4k, DCI 4k (Full Frame), UHD 8k) has been
+    added.
+
+### Fill and Stroke
+
+`Object → Fill and stroke`
+
+-   The RGBA code entry field now also accepts values like `#123` and
+    autocompletes them to `#112233`, automatically removes hash signs in
+    pasted codes, and keeps the old alpha value if the pasted code does
+    not contain any.
+-   The blur slider is now scaled quadratically as you drag the slider.
+    This makes it easier to apply and adjust smaller blur values.
+
+### Filter Editor
+
+`Filters → Filter Editor`
+
+The filter primitives now have a symbolic icon (one whose color can be
+changed).
+
+### Objects
+
+`Object → Objects`
+
+The context (right-click) menu now also contains an entry for
+**deleting** the selected object.
+
+### Paint Servers
+
+`Object → Paint Servers`
+
+-   New dialog that allows you to see a list of patterns and SVG2 hatch
+    fills used in the current document (or available by default) and to
+    assign those to objects. The hatch fills can be modified by their
+    handles on canvas [in the
+    future](https://gitlab.com/inkscape/inbox/-/issues/2526).
+-   `Server` field contains the following options: `All paint servers`,
+    `Current Document` and each document's title from the user's
+    `/paint` configuration folder.
+-   The `Change` field decides whether the fill or the stroke of the
+    object will be set to the paint server on click.
+-   You can select multiple objects or a group of objects and they will
+    all get their fill or stroke changed to the selected paint server.
+-   To add a new paint server, you need to add an `.svg` document in the
+    `/paint` user configuration folder with the following restrictions:
+    -   the svg must be valid
+    -   it must have a unique <code>title</code> property
+    -   and it must have patterns or hatches with unique ids in the
+        defs section.
+
+This functionality was added to Inkscape as a Google Summer of Code
+project. More details on it are available [in the project
+description](https://gitlab.com/vanntile/inkscape-gsoc-application#paint-servers-dialog)
+and our [news
+article](https://inkscape.org/news/2020/02/21/valentin-wrangled-meshes-hatches-and-gtk-during-su/).
+
+### Preferences
+
+`Edit → Preferences`
+
+-   The **Bitmaps** subsection has been renamed to **Imported Images**,
+    as it now applies to both imported (embedded or linked) raster
+    images as well as to imported (embedded or linked) SVG images (i.e.
+    to everything in `<img>` tags).
+-   The **System** subsection lists more relevant folders and offers
+    buttons to open those folders with the system's file browser. This
+    makes it easier to find the correct folder, e.g. for resetting the
+    preferences or for adding an extension or a new icon set.
+-   The **System** subsection now has a button for quickly resetting all
+    Inkscape preferences, which also automatically creates a backup of
+    the current preferences.
+-   An option for **scaling a stroke's dash pattern when scaling the
+    stroke width** has been added and can be found at
+    `Behaviour → Dashes`. It is activated by default.
+-   **Autosave** is now enabled by default. The default directory has
+    changed (the path is displayed in
+    `Edit → Preferences → Input/Output → Autosave: Autosave directory`).
+-   The setting for **Handle size** has been moved from **Input
+    devices** to **Interface** to make it more discoverable.
+
+### Selection Sets Dialog Hidden
+
+The **Selection Sets** dialog is deprecated and has been hidden from the
+menus. It will be removed in Inkscape 1.1 and sets created with this
+option might not work in a future Inkscape version.
+
+It can be un-hidden by assigning a keyboard shortcut to it in the
+Inkscape preferences, or by editing the file `menus.xml` in Inkscape's
+`ui` folder to uncomment the `DialogTags` entry, and saving the edited
+file in your user preferences' `ui` folder.
+
+### Selectors and CSS \[Experimental, hidden\]
+
+-   New dialog for adding classes and CSS styles to elements of the
+    drawing
+-   It is currently in experimental status, thus hidden from the menu
+    (`Edit → Selectors and CSS`)
+-   The keyboard shortcut **<kbd>Ctrl + Shift + Q</kbd>** can be used to
+    open the dialog
+-   Among the [known
+    issues](https://gitlab.com/groups/inkscape/-/issues?scope=all&utf8=%E2%9C%93&state=all&search=Selectors),
+    there are a couple crashes, which is the reason why the dialog has
+    been hidden for the 1.0 release.
+
+### Symbols
+
+`Object → Symbols`
+
+The Symbols dialog can now handle a lot of symbols without delay on
+startup, and also allows searching. Symbols and symbol sets are now
+displayed in alphabetical order.
+
+### Trace Bitmap
+
+`Path → Trace Bitmap`
+
+A new, unified dialog for vectorizing raster graphics is now available
+from `Path → Trace Bitmap`. It contains the previously separate **Trace
+pixelart** dialog and comes with a new option for **centerline
+tracing**.
+
+### Unicode Characters
+
+-   The **'Glyphs' dialog** has been **renamed to 'Unicode
+    Characters**'.
+-   The characters in the dialog's character list now **use the selected
+    font**.
+-   Each character now has a **tooltip** that shows a larger version of
+    the character, so one can more easily find the correct character.
+
+### XML Editor
+
+`Edit → XML Editor`
+
+The side of the editor that allows one to set, edit or delete attributes
+can now be panned both horizontally and vertically, or be hidden
+entirely. Long items can more easily be edited in a little popup dialog
+with a new monospaced font.
+
+Menus
+-----
+
+-   New option to `Unlink clones recursively` added into sub-menu at
+    `Edit → Clone`
+
+Customization
+----------------------------------------------
+
+### Customize many files in the share folder
+
+Many files in `/share` can be over-ridden by placing files in the user's
+configuration folder (e.g. `~/.config/inkscape`). Configurable contents
+now includes extensions, filters, fonts, gradients, icons, keyboard
+shortcuts, \[preset markers (not yet: [Issue
+\#211](https://gitlab.com/inkscape/inbox/-/issues/211))\], user paint
+servers (SVG hatches, patterns, ...), palettes, about screen, symbol
+sets, templates, tutorials and some user interface configuration files.
+Only the file 'units.xml' cannot be overridden.
+
+### Fonts
+
+#### Load additional fonts
+
+Inkscape can now load fonts that are not installed on the system. By
+default Inkscape will load additional fonts from Inkscape's share folder
+(`/share/inkscape/fonts`) and the user's configuration folder
+(`~/.config/inkscape/fonts`). Custom folders can be set in preferences
+(see `Tools → Text → Additional font directories`).
+
+### Keyboard shortcuts
+
+-   Allow to use "Super", "Hyper" and "Meta" modifier keys
+-   Improve shortcut handling code. This should fix a lot of issues and
+    allow the use of many shortcuts which were inaccessible before,
+    especially on non-English keyboard layouts.
+-   The Keyboard shortcut editor now issues a warning when the entered
+    shortcut is already in use.
+-   It is now possible to assign keyboard shortcuts that align an object
+    to the top-left, top-right, bottom-left or bottom-right corners of
+    the anchor (determined via the 'relative to:' field), or to align
+    the objects' top-left, top-right, bottom-left or bottom-right
+    corners with the opposite corner of the anchor.
+
+### User interface customization
+
+-   Inkscape is starting to use glade files for its dialogues, so they
+    can be reconfigured by users. Only one is currently supported
+    (filter editor).
+-   The contents of the menus can be configured by customising the
+    `menus.xml` file.
+-   Toolbar contents for the command bar (`commands-toolbar.ui`), the
+    snap bar (`snap-toolbar.ui`), the tool controls bars for each tool
+    (`select-toolbar.ui`), the toolbox (`tool-toolbar.ui`) is now
+    configurable.
+-   The interface colors and some more UI styles can be customized in
+    <preferences folder>`/ui/style.css` (very raw theming support).
+
+### Theme selection
+
+In `Edit → Preferences → User Interface → Theme`, users can set a custom
+GTK3 theme for Inkscape. If the theme comes with a dark variant,
+activating the 'Use dark theme' checkbox will result in the dark variant
+being used. The new theme will be applied immediately.
+
+New themes can be installed on your system to be made available in the
+list to choose from. A large selection of (more or less current) GTK3
+themes are available for download at
+[gnome-look.org](https://www.gnome-look.org/browse/cat/135/ord/top/) .
+On Windows, the new themes can be placed in
+<var>`%AppData%`</var>`\Local\themes\`, so that the full path to the
+theme's CSS files will be
+<var>`%AppData%`</var>`\Local\themes\`<theme name>`\gtk-3.0\`.
+
+### Icon set selection
+
+In `Edit → Preferences → User Interface → Theme`, the icon set to use
+can be selected. By default, Inkscape comes with 'hicolor', 'Tango', and
+the new 'Multicolor' icons. In addition to this, it offers to use the
+system's icons.
+
+The symbolic icon set that is part of the 'hicolor' icon set as well as
+the new Multicolor icons can be colorized with custom colors.
+
+### Saving the current file as template
+
+A new entry for saving the current file as a template has been added to
+the File menu. You need to specify a name for it, and optionally, you can add the template's author, a description and some keywords. A checkbox allows you to set the new template as the default template. 
+
+### Custom page sizes in Document Properties
+
+Inkscape now creates a CSV file (comma separated values) called
+`pages.csv`. It is located in your Inkscape user preferences folder,
+next to your `preferences.xml` file. This file contains the default page
+sizes that you can choose from in the 'Page' tab of the 'Document
+properties' dialog. You can edit the `pages.csv` file to remove the page
+sizes you won't use, or to add new ones.
+
+Command Line
+--------------------------------------------
+
+The Inkscape command line has undergone a major overhaul with the goal
+of making it more powerful and flexible for the user and easier to
+enhance for the developer. The most important changes are:
+
+-   Each command-line argument can now be used only once. To specify
+    multiple *actions* (*verbs*), use semicolons (e.g.
+    <code>--actions='ObjectFlipVertically;FileSave;FileClose'</code>).
+-   Many *actions* can now take arguments (separated from the *action*
+    name by a colon.
+-   [xverbs](https://wiki.inkscape.org/wiki/index.php/Using_xverbs) have been removed from Inkscape
+    (command line commands that take parameters from a file, e.g. for
+    saving the selection under a specified filename as SVG file)
+    ([mailing list
+    thread](https://sourceforge.net/p/inkscape/mailman/inkscape-devel/thread/33487d06-e3c1-a4e5-1496-7b370d672d2f%40gmail.com/#msg35392523)).
+-   -   Multiple objects in single file can be saved into individual
+    files by giving a comma separated list of objects to the command:
+    `--export-id`.
+-   Inkscape can now import a specific page of a PDF file from the
+    command line, for batch processing (new option:
+    `--pdf-page `<var>`N`</var>).
+-   For importing a PDF, the option to import via poppler is now
+    available for the command line as `pdf-poppler`.
+-   New verb allows one to swap fill and stroke style from the command
+    line: `EditSwapFillStroke` (a keyboard shortcut can now be assigned
+    to it) ([Issue \#675690
+    (lp)](https://bugs.launchpad.net/inkscape/+bug/675690))
+-   The shell mode syntax has changed, too.
+-   The file name can now be specified with `--export-filename`
+-   The command `-x` / `--extension-directory` has been removed.
+    Replaced with: `--system-data-directory` and
+    `--user-data-directory`.
+
+More information about usage and how to update your commands can be
+found at [Using the Command Line](https://wiki.inkscape.org/wiki/index.php/Using_the_Command_Line).

+Notable Bugfixes
+----------------
+
+-   Symbols: Visio Stencils loaded from `.vss` files now use their
+    actual name instead of a placeholder derived from the symbol file's
+    name ([Issue \#1676144
+    (lp)](https://bugs.launchpad.net/inkscape/+bug/1676144))
+-   Shapes on Pen and Pencil tools now retain color and width ([Issue
+    \#1707899 (lp)](https://bugs.launchpad.net/inkscape/+bug/1707899)).
+-   Text and Font dialog: The font selection no longer jumps to the top
+    of the list when clicking Apply.
+-   Docked dialogs now open on their own when the corresponding
+    functionality is called from a menu or button
+-   The icon preview dialog now correctly shows the page background
+    (Issue \#[1537497
+    (lp)](https://bugs.launchpad.net/inkscape/+bug/1537497)).
+-   As of Windows 10 (version 1809) fonts are installed into a new
+    user-specific folder by default. Allow Inkscape to recognize those
+    fonts. ([Iusse
+    \#50](https://gitlab.com/inkscape/inkscape/-/issues/50))
+-   The default Perl interpreter executable on Windows was changed from
+    `perl.exe` to `wperl.exe` which should usually avoid flashing a
+    console window. ([Issue
+    \#66](https://gitlab.com/inkscape/inkscape/-/issues/66))
+-   Some printers who don't correctly recognize the page formats sent by
+    Inkscape, printed only square excerpts of the whole image that was
+    supposed to be printed. Now they print the whole image ([Merge
+    request
+    \#407](https://gitlab.com/inkscape/inkscape/-/merge_requests/407)).
+
+For an exhaustive list of bugs that have been fixed, please see the
+[milestones page for Inkscape 1.0 on
+Launchpad](https://launchpad.net/inkscape/1.0.x) and the [list of
+milestoned issues on
+GitLab](https://gitlab.com/inkscape/inkscape/-/issues?scope=all&utf8=%E2%9C%93&state=closed&milestone_title=Inkscape%201.0).
+
+Breaking changes / Action required
+----------------------------------
+
+### For users
+
+#### Custom Icon Sets
+
+Icon sets no longer consist of a single file containing all icons.
+Instead each icon is allocated its own file. The directory structure
+must follow the [standard structure for Gnome
+icons](https://developer.gnome.org/icon-theme-spec/).
+
+If you would like to create or convert your own icon set to the new
+format, please compare the 'hicolor' and 'Tango' icon theme folders, in
+your Inkscape installation's 'share' directory for suitable examples and
+check out [ our guide to making a new multicolor icon
+theme](https://wiki.inkscape.org/wiki/index.php/Creating_a_new_multicolor_icon_theme).
+
+As a side effect of a bug fix to the icon preview dialog (see below),
+custom UI icon SVG files need to be updated to have their background
+color alpha channel set to 0 so that they display correctly (see Issue
+\#[1661989 (lp)](https://bugs.launchpad.net/inkscape/+bug/1661989)).
+
+#### Third-party extensions
+
+Most extensions that are maintained by a third-party developer (i.e.
+that are not an Inkscape stock extension) need to be updated to work
+with this version of Inkscape. Inkscape contributors have contacted many
+extension authors already to let them know about the upcoming changes.
+If your favorite third-party extension still needs to be updated to be
+compatible with Inkscape 1.0, please point its author to [the section
+about updating one's extension in the
+Wiki](https://wiki.inkscape.org/wiki/index.php/Release_notes/1.0#For_extension_writers).
+
+#### Dropped / Replaced Extensions
+
+Extensions that previously used the UniConvertor library for
+saving/opening various file formats have been removed, as well as some
+extensions that depended on third-party programs:
+
+***Import extensions that have been removed:***
+
+-   Adobe Illustrator 8.0 and below (UC) (`*.ai`) (Workaround: rename
+    the file extension to `.eps`. Newer versions can still be imported
+    if they contain an embedded PDF.)
+-   Corel DRAW Compressed Exchange files (UC) (`*.ccx`)
+-   Corel DRAW 7-X4 files (UC) (`*.cdr`) (`*.cdr` in general can still
+    be imported)
+-   Corel DRAW 7-13 template files (UC) (`*.cdt`)
+-   Computer Graphics Metafile files (UC) (`*.cgm`)
+-   Corel DRAW Presentation Exchange files (UC) (`*.cmx`)
+-   HP Graphics Language Plot file \[AutoCAD\] (UC) (`*.plt`)
+-   sK1 vector graphics files (UC) (`*.sk1`)
+-   Dia Diagram (`*.dia`) (Workaround: export as a different format from
+    [Dia](https://wiki.gnome.org/Apps/Dia/Download))
+
+***Export extensions that have been removed:***
+
+-   HP Graphics Language Plot file \[AutoCAD\] (UC) (`*.plt`)
+-   sK1 vector graphics files (UC) (`*.sk1`)
+
+***Extensions that have been replaced:***
+
+-   `Render → LaTeX`: The [EQTeXSVG
+    extension](https://www.julienvitard.eu/en/eqtexsvg_en.html)
+    (`Render → LaTeX`) that could be used to convert an inline LaTeX
+    equation into SVG paths using Python was dropped, due to its
+    external dependencies. It has been replaced by the extension
+    `Render → Mathematics → LaTeX (pdflatex)` which serves the same
+    purpose.
+
+#### Command line changes
+
+The Inkscape command line options [have changed significantly (see
+below)](#command-line). Any command line scripts that you
+have used will need to be updated for Inkscape 1.0.
+
+### For extension writers
+
+Extensions have undergone some fundamental changes.
+
+Inkscape's stock extensions **have been moved to [their own
+repository](https://gitlab.com/inkscape/extensions)** and have been
+updated for compatibility with **Python 3**. Internally, extensions have
+been reorganized, many functions have been deprecated, and new functions
+have been added.
+
+#### General
+
+-   Extensions were updated to be compatible
+    with Python 3. While we'll be migrating away from Python 2,
+    extension writers should aim for support of Python 2.7 and Python
+    3.5+ for maximum compatibility.
+-   Windows packages now ship with Python 3 (currently Python 3.7).
+    Python 2 is not bundled anymore, so make sure to update your
+    extension to be compatible.
+-   Inkscape now adds itself to search path on startup, so you should
+    always be able to call it from your extension by simply calling
+    `inkscape`, without the need to add it to search path manually, or
+    worrying about other potentially incompatible versions of Inkscape
+    being available on search path.
+-   The folder structure of Windows packages was updated: Binaries were
+    moved from the installation root to `bin/`, Inkscape's shared files
+    where moved from `share/` to a `share/inkscape` subfolder.
+-   The underscores that were previously necessary to mark elements as
+    translatable are no longer needed. Elements that are usually
+    translated are now by default included in translations. Elements
+    that are usually not translated, are not included. This can be
+    overridden by setting the `translatable="yes/no"` attribute.
+-   Extensions (including their `.inx` files) can now be put into a
+    subdirectory of the `extensions/` folder to allow for better
+    structuring and separation of extensions.
+
+#### Extension dialogs
+
+Extension dialogs have some new input types and layout options:
+
+-   new multiline text fields
+-   new file chooser fields
+-   new `appearance="url"` for [INX
+    Parameters](https://wiki.inkscape.org/wiki/index.php/INX_Parameters) of type `"description"`. You
+    can now add clickable links to your extension UI.
+-   a simpler version of the color chooser field has been added
+-   new layout options (separator, table-like layouts)
+-   all [INX Parameters](https://wiki.inkscape.org/wiki/index.php/INX_Parameters) now have the common
+    attribute `indent="`<var>`n`</var>`"` where <var>`n`</var> specifies
+    the level of indentation in the extension UI.
+-   new `label` parameter
+-   new option to include an image
+-   some confusing options have been merged
+-   new effect extension attribute `implements-custom-gui` is
+    [available](http://wiki.inkscape.org/wiki/index.php/INX_extension_descriptor_format#Attributes_description)
+    to hide the 'Extension is working' dialog.
+
+#### More info
+
+Please also note the changed [command line
+options](#command-line), if your extension calls another
+instance of Inkscape.
+
+More detailed instructions for updating old extensions are available at
+[Updating your Extension for
+1.0](https://wiki.inkscape.org/wiki/index.php/Updating_your_Extension_for_1.0). Also check the
+[extension (`inkex`) API
+documentation](https://inkscape.gitlab.io/extensions/documentation/) and
+the [stock extensions
+repository](https://gitlab.com/inkscape/extensions) for finding
+comparable extensions. If you have questions about extension
+development, you can join us in our [extension development chat
+channel](https://chat.inkscape.org/channel/inkscape_extensions).
+
+### For packagers and those who compile Inkscape
+
+-   `autotools` builds have been dropped. Please use `CMake` for
+    building Inkscape from now on. More info is available [on our
+    website](https://inkscape.org/develop/getting-started/#092-onwards).
+-   `libsoup` dependency added: we use `libsoup` for making HTTP
+    requests without a need for `dbus` and `gvfs`.
+-   double-conversion [2](https://github.com/google/double-conversion)
+    dependency added: `lib2geom` now depends on an external version of
+    the library.
+-   Inkscape now uses a git submodule for the `extensions/` directory.
+    If you have cloned the repository and are not building from the
+    release source code tarball, please note the [updated build
+    instructions](https://inkscape.org/en/develop/getting-started/)
+-   On Ubuntu 18.04, Gnome's fallback icon set (package
+    'adwaita-icon-theme-full'), that is needed to display Inkscape's
+    default icons completely, is no longer automatically installed. It
+    has been added as a 'recommends' level dependency.
+-   lib2geom: \[insert up-to-date info here\]
+-   The environment variable `INKSCAPE_PORTABLE_PROFILE_DIR` has been
+    removed. Please use the equivalent `INKSCAPE_PROFILE_DIR` instead
+    for changing the location of the profile directory at run time. (see
+    also [\#114](https://gitlab.com/inkscape/inkscape/-/issues/114))
+-   Inkscape extensions have been updated to work with Python 3, they no
+    longer depend on Python 2 (but still work with it)

+Known Issues
+------------
+
+See [our list of confirmed and ready-to-be-worked-on
+issues](https://gitlab.com/inkscape/inkscape/-/issues) and [the
+list of new user submitted issues, questions and feature
+requests](https://gitlab.com/inkscape/inbox/-/issues).
+
+Inkview
+-------
+
+**Inkview** (a simple SVG viewer) was considerably improved and got some
+new features:
+
+-   Support folders as input (will load all SVG files from the specified
+    folder)  
+    The `-r` or `--recursive` option will even allow to search
+    subfolders recursively.
+-   Implement `-t` or `--timer` option which allows to set a time after
+    which the next file will be automatically loaded.
+-   Add `-s` or `--scale` option to set a factor by which to scale the
+    displayed image.
+-   Add `-f` or `--fullscreen` option to launch Inkview in fullscreen
+    mode
+-   Many smaller fixes and improvements
