The command\n   was taught to create a stash to save the local changes.\n\n * A new builtin \"git format-rev\" is introduced for pretty formatting\n   one revision expression per line or commit object names found in\n   running text.\n\n * \"git history\" learned \"fixup\" command.\n\n * The internal URL parsing logic has been made accessible via a new\n   subcommand \"git url-parse\".\n\n * Misspelt proxy URL (e.g., httt://...) did not trigger any warning\n   or failure, which has been corrected.\n\n * Document the fact that .git/info/exclude is shared across worktrees\n   linked to the same repository.\n\n * The command line parser for \"git diff\" learned a few options take\n   only non-negative integers.\n\n * The graph output from commands like \"git log --graph\" can now be\n   limited to a specified number of lanes, preventing overly wide output\n   in repositories with many branches.\n\n * The fsmonitor daemon has been implemented for Linux.\n\n * \"git cat-file --batch\" learns an in-line command \"mailmap\"\n   that lets the user toggle use of mailmap.\n\n * The \"git pack-objects --path-walk\" traversal has been integrated\n   with several object filters, including blobless and sparse filters.\n\n * \"git push\" learned to take a \"remote group\" name to push to, which\n   causes pushes to multiple places, just like \"git fetch\" would do.\n\n * The 'git-jump' command (in contrib/) has been taught to automatically\n   pick a mode (merge, diff, or ws) when invoked without arguments.\n\n * The documentation for `push.default = simple` has been clarified to\n   better explain its behavior, making it clear that it pushes the\n   current branch to a same-named branch on the remote, and detailing\n   the upstream requirements for centralized workflows.\n\n * The documentation for \"--word-diff\" has been extended with a bit of\n   implementation detail of where these different words come from.\n\n * \"git config foo.bar=baz\" is not likely to be a request to read the\n   value of such a variable with '=' in its name; rather it is plausible\n   that the user meant \"git config set foo.bar baz\".  Give advice when\n   giving an error message.\n\n * \"git rev-list\" (and \"git log\" family of commands) learned a new \"--max-count-oldest\"\n   that picks oldest N commits in the range instead of the usual newest.\n\n\nPerformance, Internal Implementation, Development Support etc.\n--------------------------------------------------------------\n\n * Promisor remote handling has been refactored and fixed in\n   preparation for auto-configuration of advertised remotes.\n\n * Rust support is enabled by default (but still allows opting out) in\n   some future version of Git.\n\n * Preparation of the xdiff/ codebase to work with Rust.\n\n * Use a larger buffer size in the code paths to ingest pack stream.\n\n * Refactor service routines in the ref subsystem backends.\n\n * Shrink wasted memory in Myers diff that does not account for common\n   prefix and suffix removal.\n\n * Enable expensive tests to catch topics that may cause breakages on\n   integration branches closer to their origin in the contributor PR\n   builds.\n\n * \"git merge-base\" optimization.\n\n * The limit_list() function that is one of the core part of the\n   revision traversal infrastructure has been optimized by replacing\n   its use of linear list with priority queue.\n\n * In a lazy clone, \"git cherry\" and \"git grep\" often fetch necessary\n   blob objects one by one from promisor remotes.  It has been corrected\n   to collect necessary object names and fetch them in bulk to gain\n   reasonable performance.\n\n * The logic to determine that branches in an octopus merge are\n   independent has been optimized.\n\n * The consistency checks for the files reference backend have been updated\n   to skip lock files earlier, avoiding unnecessary parsing of\n   intermediate files.\n\n * The negotiation tip options in \"git fetch\" have been reworked to\n   allow requiring certain refs to be sent as \"have\" lines, and to\n   restrict negotiation to a specific set of refs.\n\n * The repacking code has been refactored and compaction of MIDX layers\n   have been implemented, and incremental strategy that does not require\n   all-into-one repacking has been introduced.\n\n * ODB transaction interface is being reworked to explicitly handle\n   object writes.\n\n * Add a new odb \"in-memory\" source that is meant to only hold\n   tentative objects (like the virtual blob object that represents the\n   working tree file used by \"git blame\").\n\n * Many uses of the_repository has been updated to use a more\n   appropriate struct repository instance in setup.c codepath.\n\n * Revision traversal optimization.\n\n * Build update.\n\n * The logic to lazy-load trees from the commit-graph has been made\n   more robust by falling back to reading the commit object when\n   the commit-graph is no longer available.\n\n * The \"name\" argument in git_connect() and related functions has been\n   converted to a \"service\" enum to improve type safety and clarify its\n   purpose.\n\n * 'git restore --staged' has been optimized to avoid unnecessarily expanding\n   the sparse index when operating on paths within the sparse checkout\n   definition, by handling sparse directory entries at the tree level.\n\n * \"git stash -p\" has been optimized by reusing cached index\n   entries in its temporary index, avoiding unnecessary lstat()\n   calls on unchanged files.\n\n * The check for non-stale commits in the priority queue used by\n   `paint_down_to_common` and `ahead_behind` has been optimized by\n   replacing an O(N) scan with an O(1) counter, yielding performance\n   improvements in repositories with wide histories.\n\n * Reachability bitmap generation has been significantly optimized. By\n   reordering tree traversal, caching object positions, and refining how\n   pseudo-merge bitmaps are constructed, the performance of \"git repack\n   --write-midx-bitmaps\" is improved, especially for large repositories\n   and when using pseudo-merges.\n\n * Adding a decimal integer with strbuf_addf(\"%u\") appears commonly;\n   they have been optimized by using a custom formatter.\n\n * Formatting object name in full hexadecimal form has been optimized\n   by using a new strbuf_add_oid_hex() helper function.\n\n * Encourage original authors to monitor the CI status.\n\n * The `git log -L` implementation has been refactored to use the\n   standard diff output pipeline, enabling pickaxe and diff-filter to\n   work as expected. Additionally, metadata-only diff formats like\n   --raw and --name-only are now supported with -L.\n\n * The loose object source has been refactored into a proper `struct\n   odb_source`.\n\n * Guidelines on how to write a cover letter for a multi-patch series\n   have been added to SubmittingPatches, which also got a new marker\n   to separate the section for typofixes.\n\n * The setup logic to discover and configure repositories has been\n   refactored, and the initialization of the object database has been\n   centralized.\n\n * Many core configuration variables have been migrated from global\n   variables into 'repo_config_values' to tie them to a specific\n   repository instance, avoiding cross-repository state leakage.\n\n * Streaming revision walks have been optimized by using a priority queue\n   for date-sorting commits, speeding up walks repositories with many\n   merges.\n\n * A recent regression in t7527 that broke TAP output has been fixed,\n   some other test noise that also broke TAP output has been silenced,\n   and 'prove' is now configured to fail on invalid TAP output to\n   prevent future regressions.\n\n * A handful of inappropriate uses of the_repository have been\n   rewritten to use the right repository structure instance in the\n   unpack-trees.c codepath.\n\n * \"git index-pack\" has been optimized by retaining child bases in the\n   delta cache instead of immediately freeing them, letting the existing\n   cache limit policy decide eviction.\n\n\nFixes since v2.54\n-----------------\n\n * Code clean-up to use the right instance of a repository instance in\n   calls inside refs subsystem.\n   (merge 57c590feb9 sp/refs-reduce-the-repository later to maint).\n\n * The check that implements the logic to see if an in-core cache-tree\n   is fully ready to write out a tree object was broken, which has\n   been corrected.\n   (merge 521731213c dl/cache-tree-fully-valid-fix later to maint).\n\n * The test suite harness and many individual test scripts have been\n   updated to work correctly when 'set -e' is in effect, which helps\n   detect misspelled test commands.\n   (merge ffe8005b9d ps/test-set-e-clean later to maint).\n\n * Revert a recent change that introduced a regression to help mksh users.\n\n * Update various GitHub Actions versions.\n\n * Avoid hitting the pathname limit for socks proxy socket during the\n   test..\n\n * To help Windows 10 installations, avoid removing files whose\n   contents are still mmap()'ed.\n\n * The 'git backfill' command now rejects revision-limiting options that\n   are incompatible with its operation, uses standard documentation for\n   revision ranges, and includes blobs from boundary commits by default\n   to improve performance of subsequent operations.\n   (merge a1ad4a0fca en/backfill-fixes-and-edges later to maint).\n\n * \"git grep\" update.\n   (merge 9ff4b5ab1b rs/grep-column-only-match-fix later to maint).\n\n * Headers from glibc 2.43 when used with clang does not allow\n   disabling C11 language features, causing build failures..\n\n * The 'http.emptyAuth=auto' configuration now correctly attempts\n   Negotiate authentication before falling back to manual credentials.\n   This allows seamless Kerberos ticket-based authentication without\n   requiring users to explicitly set 'http.emptyAuth=true'.\n   (merge 4919938d28 mc/http-emptyauth-negotiate-fix later to maint).\n\n * Ramifications of turning off commit-graph has been documented a bit\n   more clearly.\n   (merge 48c855bb8f kh/doc-commit-graph later to maint).\n\n * \"git rebase --update-refs\", when used with an rebase.instructionFormat\n   with \"%d\" (describe) in it, tried to update local branch HEAD by\n   mistake, which has been corrected.\n   (merge 106b6885c7 ag/rebase-update-refs-limit-to-branches later to maint).\n\n * Tweak the way how sideband messages from remote are printed while\n   we talk with a remote repository to avoid tickling terminal\n   emulator glitches.\n   (merge 31e8fcabd8 rs/sideband-clear-line-before-print later to maint).\n\n * The configuration variable submodule.fetchJobs was not read correctly,\n   which has been corrected.\n   (merge aa45a5902f sj/submodule-update-clone-config-fix later to maint).\n\n * Update code paths that assumed \"unsigned long\" was long enough for\n   \"size_t\".\n   (merge 7a094d68a2 js/objects-larger-than-4gb-on-windows later to maint).\n\n * Stop using unmaintained custom allocator in Windows build which was\n   the last user of the code.\n\n * The computation to shorten the filenames shown in diffstat measured\n   width of individual UTF-8 characters to add up, but forgot to take\n   into account error cases (e.g., an invalid UTF-8 sequence, or a\n   control character).\n   (merge 09d86a3b98 en/diffstat-utf8-truncation-fix later to maint).\n\n * Some tests assume that bare repository accesses are by default\n   allowed; rewrite some of them to avoid the assumption, rewrite\n   others to explicitly set safe.bareRepository to allow them.\n   (merge 985b38ca6c js/adjust-tests-to-explicitly-access-bare-repo later to maint).\n\n * Signing commit with custom encoding was passing the data to be\n   signed at a wrong stage in the pipeline, which has been corrected.\n   (merge 7735d7eee3 bc/sign-commit-with-custom-encoding later to maint).\n\n * Further update to the i18n alias support to avoid regressions.\n\n * \"git fetch --deepen=<n>\" in a full clone truncated the history to <n>\n   commits deep, which has been corrected to be a no-op instead.\n   (merge 2431f5e0e5 sp/shallow-deepen-on-non-shallow-repo-fix later to maint).\n\n * \"git maintenance\" that goes background did not use the lockfile to\n   prevent multiple maintenance processes from running at the same\n   time, which has been corrected.\n   (merge 29364f1624 ps/maintenance-daemonize-lockfix later to maint).\n\n * Remove ineffective strbuf presizing that would have computed an\n   allocation that would not have fit in the available memory anyway,\n   or too small due to integer wraparound to cause immediate automatic\n   growing.\n   (merge a9ce8526dc jk/pretty-no-strbuf-presizing later to maint).\n\n * The HTTP walker misinterpreted the alternates file that gives an\n   absolute path when the server URL does not have the final slash\n   (i.e., \"https://example.com\" not \"https://example.com/\").\n   (merge b92387cd55 jk/dumb-http-alternate-fix later to maint).\n\n * \"git bisect\" now uses the selected terms (e.g., old/new) more\n   consistently in its output.\n   (merge cb55991825 jr/bisect-custom-terms-in-output later to maint).\n\n * Update GitLab CI jobs that exercise macOS.\n   (merge 62319b49bb ps/gitlab-ci-macOS-improvements later to maint).\n\n * \"Friday noon\" asked in the morning on Sunday was parsed to be one\n   day before the specified time, which has been corrected.\n   (merge b809304101 ta/approxidate-noon-fix later to maint).\n\n * The GIT_WORK_TREE variable prepared to invoke the push-to-checkout\n   hook was leaking into the environment even when there was no hook\n   used and broke the default push-to-deploy (i.e., let \"git checkout\"\n   update the working tree only when the working tree is clean).\n   (merge 44d04e4426 ar/receive-pack-worktree-env later to maint).\n\n * A batch of documentation pages has been updated to use the modern\n   synopsis style.\n   (merge 2ef248ae45 ja/doc-synopsis-style-again later to maint).\n\n * The \"promisor.quiet\" configuration variable was not used from\n   relevant submodules when commands like \"grep --recurse-submodules\"\n   triggered a lazy fetch, which has been corrected.\n   (merge fa1468a1f7 th/promisor-quiet-per-repo later to maint).\n\n * Correct use of sockaddr API in \"git daemon\".\n   (merge 422a5bf575 st/daemon-sockaddr-fixes later to maint).\n\n * A memory leak in `fetch_and_setup_pack_index()` when verification of\n   the downloaded pack index fails has been plugged. Also an obsolete\n   `unlink()` call on parse failure has been cleaned up.\n\n * In t3070-wildmatch, \"via ls-files\" test variants with patterns\n   containing backslash escapes are now skipped on Windows, avoiding 36\n   test failures caused by pathspec separator conversion.\n   (merge 8c84e6802c kk/wildmatch-windows-ls-files-prereq later to maint).\n\n * A linker warning on macOS when building with Xcode 16.3 or newer has\n   been avoided by passing -fno-common to the compiler when a\n   sufficiently new linker is detected.\n   (merge 5cd4d0d850 hn/macos-linker-warning later to maint).\n\n * Documentation and tests have been added to clarify that Git's internal\n   raw timestamp format requires a `@` prefix for values less than\n   100,000,000 to prevent ambiguity with other formats like YYYYMMDD.\n   (merge 4018dc29ee ls/doc-raw-timestamp-prefix later to maint).\n\n * Wording used in \"format-patch --subject-prefix\" documentation\n   has been improved.\n   (merge 4a1eb9304a lo/doc-format-patch-subject-prefix later to maint).\n\n * Advanced emulation of kill() used on Windows in GfW has been\n   upstreamed to improve the symptoms like left-behind .lock files and\n   that fails to let the child clean-up itself when it gets killed.\n   (merge 363f1d8b3a js/win-kill-child-more-gently later to maint).\n\n * The 'git describe --contains --all' command has been fixed to\n   properly honor the '--match' and '--exclude' options by passing\n   them down to 'git name-rev' with the appropriate reference\n   prefixes.\n   (merge 1891707d1b jk/describe-contains-all-match-fix later to maint).\n\n * Various typos, grammatical errors, and duplicated words in both\n   documentation and code comments have been corrected.\n   (merge dc6068df67 wy/docs-typofixes later to maint).\n\n * The subprocess handshake during startup has been made gentler by using\n   packet_read_line_gently() instead of packet_read_line() to prevent the\n   parent Git process from dying abruptly when a configured subprocess\n   (e.g., a clean/smudge filter) fails to start.\n   (merge 061a68e443 mm/subprocess-handshake-fix later to maint).\n\n * Other code cleanup, docfix, build fix, etc.\n   (merge 80f4b802e9 ja/doc-difftool-synopsis-style later to maint).\n   (merge b96490241e jc/doc-timestamps-in-stat later to maint).\n   (merge ef85286e51
