Now the latter + just gives an empty output, while the former still gives an error + message. + + * Introduce a case insensitive mode to the Bash completion helpers. + + * The advice message given by "git status" when it takes long time to + enumerate untracked paths has been updated. + + * Just like "git var GIT_EDITOR" abstracts the complex logic to + choose which editor gets used behind it, "git var" now give support + to GIT_SEQUENCE_EDITOR. + + * "git format-patch" learned to honor format.mboxrd even when sending + patches to the standard output stream, + + * 'cat-file' gains mailmap support for its '--batch-check' and '-s' + options. + + * Conditionally skip the pre-applypatch and applypatch-msg hooks when + applying patches with 'git am'. + + * Introduce an optional configuration to allow the trailing hash that + protects the index file from bit flipping. + + * "git check-attr" learned to take an optional tree-ish to read the + .gitattributes file from. + + * "scalar" learned to give progress bar. + + * "grep -P" learned to use Unicode Character Property to grok + character classes when processing \b and \w etc. + + * "git rebase" often ignored incompatible options instead of + complaining, which has been corrected. + + * "scalar" warns but continues when its periodic maintenance + feature cannot be enabled. + + * The bundle-URI subsystem adds support for creation-token heuristics + to help incremental fetches. + + * Userdiff regexp update for Java language. + + * "git fetch --jobs=0" used to hit a BUG(), which has been corrected + to use the available CPUs. + + * An invalid label or ref in the "rebase -i" todo file used to + trigger an runtime error. SUch an error is now diagnosed while the + todo file is parsed. + + * The "diff" drivers specified by the "diff" attribute attached to + paths can now specify which algorithm (e.g. histogram) to use. + + * "git range-diff" learned --abbrev= option. + + * "git archive HEAD^{tree}" records the paths with the current + timestamp in the archive, making it harder to obtain a stable + output. The command learned the --mtime option to specify an + arbitrary timestamp (e.g. --mtime="@0 +0000" for the epoch). + + * The credential subsystem learned that a password may have an + explicit expiration. + + * The format.attach configuration variable lacked a way to override a + value defined in a lower-priority configuration file (e.g. the + system one) by redefining it in a higher-priority configuration + file. Now, setting format.attach to an empty string means show the + patch inline in the e-mail message, without using MIME attachment. + + This is a backward incompatible change. + + +Performance, Internal Implementation, Development Support etc. + + * `git bisect` becomes a builtin. + + * The pack-bitmap machinery is taught to log the paths of redundant + bitmap(s) to trace2 instead of stderr. + + * Use the SHA1DC implementation on macOS, just like other platforms, + by default. + + * Even in a repository with promisor remote, it is useless to + attempt to lazily attempt fetching an object that is expected to be + commit, because no "filter" mode omits commit objects. Take + advantage of this assumption to fail fast on errors. + + * Stop using "git --super-prefix" and narrow the scope of its use to + the submodule--helper. + + * Stop running win+VS build by default. + + * CI updates. We probably want a clean-up to move the long shell + script embedded in yaml file into a separate file, but that can + come later. + + * Use `git diff --no-index` as a test_cmp on Windows. + + We'd probably need to revisit "do we really want to, and have to, + lose CRLF vs LF?" later, at which time we may be able to further + clean this up by replacing "git diff --no-index" with "diff -u". + + * Avoid unnecessary builds in CI, with settings configured in + ci-config. + + * Plug leaks in sequencer subsystem and its users. + + * In-tree .gitattributes update to match the way we recommend our + users to mark a file as text. + (merge 1f34e0cd3d po/attributes-text later to maint). + + * Finally retire the scripted "git add -p/-i" implementation and have + everybody use the one reimplemented in C. + + +Fixes since v2.39 +----------------- + + * Various leak fixes. + + * Fix a bug where `pack-objects` would not respect multiple `--filter` + arguments when invoked directly. + (merge d4f7036887 rs/multi-filter-args later to maint). + + * Make fsmonitor more robust to avoid the flakiness seen in t7527. + (merge 6692d45477 jh/t7527-unflake-by-forcing-cookie later to maint). + + * Stop using deprecated macOS API in fsmonitor. + (merge b0226007f0 jh/fsmonitor-darwin-modernize later to maint). + + * Redefining system functions for a few functions did not follow our + usual "implement git_foo() and #define foo(args) git_foo(args)" + pattern, which has broken build for some folks. + + * The way the diff machinery prepares the options array for the + parse_options API has been refactored to avoid resource leaks. + (merge 189e97bc4b rs/diff-parseopts later to maint). + + * Correct pthread API usage. + (merge 786e67611d sx/pthread-error-check-fix later to maint). + + * The code to auto-correct a misspelt subcommand unnecessarily called + into git_default_config() from the early config codepath, which was + a no-no. This has bee corrected. + (merge 0918d08887 sg/help-autocorrect-config-fix later to maint). + + * "git http-fetch" (which is rarely used) forgot to identify itself + in the trace2 output. + (merge 7abb43cbc8 jt/http-fetch-trace2-report-name later to maint). + + * The output from "git diff --stat" on an unmerged path lost the + terminating LF in Git 2.39, which has been corrected. + (merge 209d9cb011 pg/diff-stat-unmerged-regression-fix later to maint). + + * "git pull -v --recurse-submodules" attempted to pass "-v" down to + underlying "git submodule update", which did not understand the + request and barfed, which has been corrected. + (merge 6f65f84766 ss/pull-v-recurse-fix later to maint). + + * When given a pattern that matches an empty string at the end of a + line, the code to parse the "git diff" line-ranges fell into an + infinite loop, which has been corrected. + + * Fix the sequence to fsync $GIT_DIR/packed-refs file that forgot to + flush its output to the disk.. + + * Fix to a small regression in 2.38 days. + + * "git diff --relative" did not mix well with "git diff --ext-diff", + which has been corrected. + + * The logic to see if we are using the "cone" mode by checking the + sparsity patterns has been tightened to avoid mistaking a pattern + that names a single file as specifying a cone. + + * Deal with a few deprecation warning from cURL library. + + * Doc update for environment variables set when hooks are invoked. + + * Document ORIG_HEAD a bit more. + + * "git ls-tree --format='%(path) %(path)' $tree $path" showed the + path three times, which has been corrected. + + * Remove "git env--helper" and demote it to a test-tool subcommand. + (merge 4a1baacd46 ab/test-env-helper later to maint). + + * Newer regex library macOS stopped enabling GNU-like enhanced BRE, + where '\(A\|B\)' works as alternation, unless explicitly asked with + the REG_ENHANCED flag. "git grep" now can be compiled to do so, to + retain the old behaviour. + + * Pthread emulation on Win32 leaked thread handle when a thread is + joined. + (merge 238a9dfe86 sk/win32-close-handle-upon-pthread-join later to maint). + + * "git send-email -v 3" used to be expanded to "git send-email + --validate 3" when the user meant to pass them down to + "format-patch", which has been corrected. + (merge 8774aa56ad km/send-email-with-v-reroll-count later to maint). + + * Document that "branch -f " disables only the safety to + avoid recreating an existing branch. + + * "git fetch ", when "" of remotes lists the same + remote twice, unnecessarily failed when parallel fetching was + enabled, which has been corrected. + (merge 06a668cb90 cw/fetch-remote-group-with-duplication later to maint). + + * Clarify how "checkout -b/-B" and "git branch [-f]" are similar but + different in the documentation. + + * "git hash-object" now checks that the resulting object is well + formed with the same code as "git fsck". + (merge 8e4309038f jk/hash-object-fsck later to maint). + + * Improve the error message given when private key is not loaded in + the ssh agent in the codepath to sign with an ssh key. + (merge dce7b31126 as/ssh-signing-improve-key-missing-error later to maint). + + * Adjust "git request-pull" to strip embedded signature from signed + tags to notice non-PGP signatures. + (merge a9cad02538 gm/request-pull-with-non-pgp-signed-tags later to maint). + + * Remove support for MSys, which now lags way behind MSys2. + (merge 2987407f3c hj/remove-msys-support later to maint). + + * Fix use of CreateThread() API call made early in the windows + start-up code. + (merge 592bcab61b sk/winansi-createthread-fix later to maint). + + * "git pack-objects" learned to release delta-island bitmap data when + it is done using it, saving peak heap memory usage. + (merge 647982bb71 ew/free-island-marks later to maint). + + * In an environment where dynamically generated code is prohibited to + run (e.g. SELinux), failure to JIT pcre patterns is expected. Fall + back to interpreted execution in such a case. + (merge 50b6ad55b0 cb/grep-fallback-failing-jit later to maint). + + * "git name-rev" heuristics update. + (merge b2182a8730 en/name-rev-make-taggerdate-much-less-important later to maint). + + * Remove more remaining uses of macros that relies on the_index + singleton instance without explicitly spelling it out. + + * Remove unnecessary explicit sizing of strbuf. + (merge 93ea118bed rs/cache-tree-strbuf-growth-fix later to maint). + + * Doc update. + (merge d9ec3b0dc0 jk/doc-ls-remote-matching later to maint). + + * Error messages given upon a signature verification failure used to + discard the errors from underlying gpg program, which has been + corrected. + (merge ad6b320756 js/gpg-errors later to maint). + + * Update --date=default documentation. + (merge 9deef088ae rd/doc-default-date-format later to maint). + + * A test helper had a single write(2) of 256kB, which was too big for + some platforms (e.g. NonStop), which has been corrected by using + xwrite() wrapper appropriately. + (merge 58eab6ff13 jc/genzeros-avoid-raw-write later to maint). + + * sscanf(3) used in "git symbolic-ref --short" implementation found + to be not working reliably on macOS in UTF-8 locales.
