-Git 2.28 Release Notes
-======================
-
-Updates since v2.27
--------------------
-
-Backward compatibility notes
-
- * "fetch.writeCommitGraph" is deemed to be still a bit too risky and
-   is no longer part of the "feature.experimental" set.
-
-
-UI, Workflows & Features
-
- * The commands in the "diff" family learned to honor "diff.relative"
-   configuration variable.
-
- * The check in "git fsck" to ensure that the tree objects are sorted
-   still had corner cases it missed unsorted entries.
-
- * The interface to redact sensitive information in the trace output
-   has been simplified.
-
- * The command line completion (in contrib/) learned to complete
-   options that the "git switch" command takes.
-
- * "git diff" used to take arguments in random and nonsense range
-   notation, e.g. "git diff A..B C", "git diff A..B C...D", etc.,
-   which has been cleaned up.
-
- * "git diff-files" has been taught to say paths that are marked as
-   intent-to-add are new files, not modified from an empty blob.
-
- * "git status" learned to report the status of sparse checkout.
-
- * "git difftool" has trouble dealing with paths added to the index
-   with the intent-to-add bit.
-
- * "git fast-export --anonymize" learned to take customized mapping to
-   allow its users to tweak its output more usable for debugging.
-
- * The command line completion support (in contrib/) used to be
-   prepared to work with "set -u" but recent changes got a bit more
-   sloppy.  This has been corrected.
-
- * "git gui" now allows opening work trees from the start-up dialog.
-
-
-Performance, Internal Implementation, Development Support etc.
-
- * Code optimization for a common case.
-   (merge 8777616e4d an/merge-single-strategy-optim later to maint).
-
- * We've adopted a convention that any on-stack structure can be
-   initialized to have zero values in all fields with "= { 0 }",
-   even when the first field happens to be a pointer, but sparse
-   complained that a null pointer should be spelled NULL for a long
-   time.  Start using -Wno-universal-initializer option to squelch
-   it (the latest sparse has it on by default).
-
- * "git log -L..." now takes advantage of the "which paths are touched
-   by this commit?" info stored in the commit-graph system.
-
- * As FreeBSD is not the only platform whose regexp library reports
-   a REG_ILLSEQ error when fed invalid UTF-8, add logic to detect that
-   automatically and skip the affected tests.
-
- * "git bugreport" learns to report what shell is in use.
-
- * Support for GIT_CURL_VERBOSE has been rewritten in terms of
-   GIT_TRACE_CURL.
-
- * Preliminary clean-ups around refs API, plus file format
-   specification documentation for the reftable backend.
-
- * Workaround breakage in MSVC build, where "curl-config --cflags"
-   gives settings appropriate for GCC build.
-
- * Code clean-up of "git clean" resulted in a fix of recent
-   performance regression.
-
- * Code clean-up in the codepath that serves "git fetch" continues.
-
- * "git merge-base --is-ancestor" is taught to take advantage of the
-   commit graph.
-
- * Rewrite of parts of the scripted "git submodule" Porcelain command
-   continues; this time it is "git submodule set-branch" subcommand's
-   turn.
-
- * The "fetch/clone" protocol has been updated to allow the server to
-   instruct the clients to grab pre-packaged packfile(s) in addition
-   to the packed object data coming over the wire.
-
- * A misdesigned strbuf_write_fd() function has been retired.
-
- * SHA-256 migration work continues, including CVS/SVN interface.
-
- * A few fields in "struct commit" that do not have to always be
-   present have been moved to commit slabs.
-
- * API cleanup for get_worktrees()
-
- * By renumbering object flag bits, "struct object" managed to lose
-   bloated inter-field padding.
-
- * The name of the primary branch in existing repositories, and the
-   default name used for the first branch in newly created
-   repositories, is made configurable, so that we can eventually wean
-   ourselves off of the hardcoded 'master'.
-
- * The effort to avoid using test_must_fail on non-git command continues.
-
- * In 2.28-rc0, we corrected a bug that some repository extensions are
-   honored by mistake even in a version 0 repositories (these
-   configuration variables in extensions.* namespace were supposed to
-   have special meaning in repositories whose version numbers are 1 or
-   higher), but this was a bit too big a change.  The behaviour in
-   recent versions of Git where certain extensions.* were honored by
-   mistake even in version 0 repositories has been restored.
-
-
-Fixes since v2.27
------------------
-
- * The "--prepare-p4-only" option of "git p4" is supposed to stop
-   after replaying one changeset, but kept going (by mistake?)
-
- * The error message from "git checkout -b foo -t bar baz" was
-   confusing.
-
- * Some repositories in the wild have commits that record nonsense
-   committer timezone (e.g. rails.git); "git fast-import" learned an
-   option to pass these nonsense timestamps intact to allow recreating
-   existing repositories as-is.
-   (merge d42a2fb72f en/fast-import-looser-date later to maint).
-
- * The command line completion script (in contrib/) tried to complete
-   "git stash -p" as if it were "git stash push -p", but it was too
-   aggressive and also affected "git stash show -p", which has been
-   corrected.
-   (merge fffd0cf520 vs/complete-stash-show-p-fix later to maint).
-
- * On-the-wire protocol v2 easily falls into a deadlock between the
-   remote-curl helper and the fetch-pack process when the server side
-   prematurely throws an error and disconnects.  The communication has
-   been updated to make it more robust.
-
- * "git checkout -p" did not handle a newly added path at all.
-   (merge 2c8bd8471a js/checkout-p-new-file later to maint).
-
- * The code to parse "git bisect start" command line was lax in
-   validating the arguments.
-   (merge 4d9005ff5d cb/bisect-helper-parser-fix later to maint).
-
- * Reduce memory usage during "diff --quiet" in a worktree with too
-   many stat-unmatched paths.
-   (merge d2d7fbe129 jk/diff-memuse-optim-with-stat-unmatch later to maint).
-
- * The reflog entries for "git clone" and "git fetch" did not
-   anonymize the URL they operated on.
-   (merge 46da295a77 js/reflog-anonymize-for-clone-and-fetch later to maint).
-
- * The behaviour of "sparse-checkout" in the state "git clone
-   --no-checkout" left was changed accidentally in 2.27, which has
-   been corrected.
-
- * Use of negative pathspec, while collecting paths including
-   untracked ones in the working tree, was broken.
-
- * The same worktree directory must be registered only once, but
-   "git worktree move" allowed this invariant to be violated, which
-   has been corrected.
-   (merge 810382ed37 es/worktree-duplicate-paths later to maint).
-
- * The effect of sparse checkout settings on submodules is documented.
-   (merge e7d7c73249 en/sparse-with-submodule-doc later to maint).
-
- * Code clean-up around "git branch" with a minor bugfix.
-   (merge dc44639904 dl/branch-cleanup later to maint).
-
- * A branch name used in a test has been clarified to match what is
-   going on.
-   (merge 08dc26061f pb/t4014-unslave later to maint).
-
- * An in-code comment in "git diff" has been updated.
-   (merge c592fd4c83 dl/diff-usage-comment-update later to maint).
-
- * The documentation and some tests have been adjusted for the recent
-   renaming of "pu" branch to "seen".
-   (merge 6dca5dbf93 js/pu-to-seen later to maint).
-
- * The code to push changes over "dumb" HTTP had a bad interaction
-   with the commit reachability code due to incorrect allocation of
-   object flag bits, which has been corrected.
-   (merge 64472d15e9 bc/http-push-flagsfix later to maint).
-
- * "git send-email --in-reply-to=<msg>" did not use the In-Reply-To:
-   header with the value given from the command line, and let it be
-   overridden by the value on In-Reply-To: header in the messages
-   being sent out (if exists).
-   (merge f9f60d7066 ra/send-email-in-reply-to-from-command-line-wins later to maint).
-
- * "git log -Lx,y:path --before=date" lost track of where the range
-   should be because it didn't take the changes made by the youngest
-   commits that are omitted from the output into account.
-
- * When "fetch.writeCommitGraph" configuration is set in a shallow
-   repository and a fetch moves the shallow boundary, we wrote out
-   broken commit-graph files that do not match the reality, which has
-   been corrected.
-
- * "git checkout" failed to catch an error from fstat() after updating
-   a path in the working tree.
-   (merge 35e6e212fd mt/entry-fstat-fallback-fix later to maint).
-
- * When an aliased command, whose output is piped to a pager by git,
-   gets killed by a signal, the pager got into a funny state, which
-   has been corrected (again).
-   (merge c0d73a59c9 ta/wait-on-aliased-commands-upon-signal later to maint).
-
- * The code to produce progress output from "git commit-graph --write"
-   had a few breakages, which have been fixed.
-
- * Other code cleanup, docfix, build fix, etc.
-   (merge 2c31a7aa44 jx/pkt-line-doc-count-fix later to maint).
-   (merge d63ae31962 cb/t5608-cleanup later to maint).
-   (merge 788db145c7 dl/t-readme-spell-git-correctly later to maint).
-   (merge 45a87a83bb dl/python-2.7-is-the-floor-version later to maint).
-   (merge b75a219904 es/advertise-contribution-doc later to maint).
-   (merge 0c9a4f638a rs/pull-leakfix later to maint).
-   (merge d546fe2874 rs/commit-reach-leakfix later to maint).
-   (merge 087bf5409c mk/pb-pretty-email-without-domain-part-fix later to maint).
-   (merge 5f4ee57ad9 es/worktree-code-cleanup later to maint).
-   (merge 0172f7834a cc/cat-file-usage-update later to maint).
-   (merge 81de0c01cf ma/rebase-doc-typofix later to maint).
