is not scheduled to happen in the upcoming release (yet).
* The historical argument order "git merge <msg> HEAD <commit>..."
- has been deprecated for quite some time, and will be removed in the
- upcoming release.
+ has been deprecated for quite some time, and will be removed in a
+ future release.
+
+ * An ancient script "git relink" has been removed.
Updates since v2.11
the previous hack that depended on internals of (older) MSVC
runtime.
+ * Some platforms no longer understand "latin-1" that is still seen in
+ the wild in e-mail headers; replace them with "iso-8859-1" that is
+ more widely known when conversion fails from/to it.
+
+ * "git grep" has been taught to optionally recurse into submodules.
+
+ * "git rm" used to refuse to remove a submodule when it has its own
+ git repository embedded in its working tree. It learned to move
+ the repository away to $GIT_DIR/modules/ of the superproject
+ instead, and allow the submodule to be deleted (as long as there
+ will be no loss of local modifications, that is).
+
+ * A recent updates to "git p4" was not usable for older p4 but it
+ could be made to work with minimum changes. Do so.
+
+ * "git diff" learned diff.interHunkContext configuration variable
+ that gives the default value for its --inter-hunk-context option.
+
+ * The prereleaseSuffix feature of version comparison that is used in
+ "git tag -l" did not correctly when two or more prereleases for the
+ same release were present (e.g. when 2.0, 2.0-beta1, and 2.0-beta2
+ are there and the code needs to compare 2.0-beta1 and 2.0-beta2).
+
+ * "git submodule push" learned "--recurse-submodules=only option to
+ push submodules out without pushing the top-level superproject.
+
+ * "git tag" and "git verify-tag" learned to put GPG verification
+ status in their "--format=<placeholders>" output format.
+
+ * An ancient repository conversion tool left in contrib/ has been
+ removed.
+
+ * "git show-ref HEAD" used with "--verify" because the user is not
+ interested in seeing refs/remotes/origin/HEAD, and used with
+ "--head" because the user does not want HEAD to be filtered out,
+ i.e. "git show-ref --head --verify HEAD", did not work as expected.
+
+ * "git submodule add" used to be confused and refused to add a
+ locally created repository; users can now use "--force" option
+ to add them.
+ (merge 619acfc78c sb/submodule-add-force later to maint).
+
+ * Some people feel the default set of colors used by "git log --graph"
+ rather limiting. A mechanism to customize the set of colors has
+ been introduced.
+
+ * "git read-tree" and its underlying unpack_trees() machinery learned
+ to report problematic paths prefixed with the --super-prefix option.
+
+ * When a submodule "A", which has another submodule "B" nested within
+ it, is "absorbed" into the top-level superproject, the inner
+ submodule "B" used to be left in a strange state. The logic to
+ adjust the .git pointers in these submodules has been corrected.
+
+ * The user can specify a custom update method that is run when
+ "submodule update" updates an already checked out submodule. This
+ was ignored when checking the submodule out for the first time and
+ we instead always just checked out the commit that is bound to the
+ path in the superproject's index.
+
+ * The command line completion (in contrib/) learned that
+ "git diff --submodule=" can take "diff" as a recently added option.
+
+ * The "core.logAllRefUpdates" that used to be boolean has been
+ enhanced to take 'always' as well, to record ref updates to refs
+ other than the ones that are expected to be updated (i.e. branches,
+ remote-tracking branches and notes).
+
+ * Comes with more command line completion (in contrib/) for recently
+ introduced options.

code with "git interpret-trailer".
* The default Travis-CI configuration specifies newer P4 and GitLFS.
- (merge 5f703e8f02 ls/travis-update-p4-and-lfs later to maint).
* The "fast hash" that had disastrous performance issues in some
corner cases has been retired from the internal diff.
* The character width table has been updated to match Unicode 9.0
- (merge 9e6e9aefdf bb/unicode-9.0 later to maint).
* Update the procedure to generate "tags" for developer support.
- (merge 046e4c1c09 jk/make-tags-find-sources-tweak later to maint).
+ * The codeflow of setting NOATIME and CLOEXEC on file descriptors Git
+ opens has been simplified.
+
+ * "git diff" and its family had two experimental heuristics to shift
+ the contents of a hunk to make the patch easier to read. One of
+ them turns out to be better than the other, so leave only the
+ "--indent-heuristic" option and remove the other one.
+
+ * A new submodule helper "git submodule embedgitdirs" to make it
+ easier to move embedded .git/ directory for submodules in a
+ superproject to .git/modules/ (and point the latter with the former
+ that is turned into a "gitdir:" file) has been added.
+
+ * "git push \\server\share\dir" has recently regressed and then
+ fixed. A test has retroactively been added for this breakage.
+
+ * Build updates for Cygwin.
+
+ * The implementation of "real_path()" was to go there with chdir(2)
+ and call getcwd(3), but this obviously wouldn't be usable in a
+ threaded environment. Rewrite it to manually resolve relative
+ paths including symbolic links in path components.
+
+ * Adjust documentation to help AsciiDoctor render better while not
+ breaking the rendering done by AsciiDoc.
+
+ * The sequencer machinery has been further enhanced so that a later
+ set of patches can start using it to reimplement "rebase -i".
+
+ * Update the definition of the MacOSX test environment used by
+ TravisCI.
+
+ * Rewrite a scripted porcelain "git difftool" in C.
+
+ * "make -C t failed" will now run only the tests that failed in the
+ previous run. This is usable only when prove is not use, and gives
+ a useless error message when run after "make clean", but otherwise
+ is serviceable.
+
+ * "uchar [40]" to "struct object_id" conversion continues.
Also contains various documentation updates and code clean-ups.
standard I/O streams are connected to a TTY, but isatty() that
comes with Windows incorrectly returned true if it is used on NUL
(i.e. an equivalent to /dev/null). This has been fixed.
- (merge cbb3f3c9b1 js/mingw-isatty later to maint).
* "git svn" did not work well with path components that are "0", and
some configuration variable it uses were not documented.
- (merge ea9a93dcc2 ew/svn-fixes later to maint).
* "git rev-parse --symbolic" failed with a more recent notation like
"HEAD^-1" and "HEAD^!".
- (merge a2e7b04c44 jk/rev-parse-symbolic-parents-fix later to maint).
* An empty directory in a working tree that can simply be nuked used
to interfere while merging or cherry-picking a change to create a
submodule directory there, which has been fixed..
- (merge 5423d2e700 dt/empty-submodule-in-merge later to maint).
* The code in "git push" to compute if any commit being pushed in the
superproject binds a commit in a submodule that hasn't been pushed
out was overly inefficient, making it unusable even for a small
project that does not have any submodule but have a reasonable
number of refs.
- (merge 250ab24ab3 hv/submodule-not-yet-pushed-fix later to maint).
* "git push --dry-run --recurse-submodule=on-demand" wasn't
"--dry-run" in the submodules.
- (merge 0301c821c5 bw/push-dry-run later to maint).
* The output from "git worktree list" was made in readdir() order,
and was unstable.
- (merge 4df1d4d466 nd/worktree-list-fixup later to maint).
* mergetool.<tool>.trustExitCode configuration variable did not apply
to built-in tools, but now it does.
- (merge 2967284456 da/mergetool-trust-exit-code later to maint).
* "git p4" LFS support was broken when LFS stores an empty blob.
- (merge d5eb3cf5e7 ls/p4-empty-file-on-lfs later to maint).
* A corner case in merge-recursive regression that crept in
during 2.10 development cycle has been fixed.
- (merge 1c25d2d8ed jc/renormalize-merge-kill-safer-crlf later to maint).
* Transport with dumb http can be fooled into following foreign URLs
that the end user does not intend to, especially with the server
side redirects and http-alternates mechanism, which can lead to
security issues. Tighten the redirection and make it more obvious
to the end user when it happens.
- (merge cb4d2d35c4 jk/http-walker-limit-redirect-2.9 later to maint).
* Update the error messages from the dumb-http client when it fails
to obtain loose objects; we used to give sensible error message
only upon 404 but we now forbid unexpected redirects that needs to
be reported with something sensible.
- (merge 3680f16f9d jk/http-walker-limit-redirect later to maint).
* When diff.renames configuration is on (and with Git 2.9 and later,
it is enabled by default, which made it worse), "git stash"
misbehaved if a file is removed and another file with a very
similar content is added.
- (merge 9d4e28ead5 jk/stash-disable-renames-internally later to maint).
* "git diff --no-index" did not take "--no-abbrev" option.
- (merge 43d1948b7b jb/diff-no-index-no-abbrev later to maint).
* "git difftool --dir-diff" had a minor regression when started from
a subdirectory, which has been fixed.
- (merge 853e10c197 da/difftool-dir-diff-fix later to maint).
* "git commit --allow-empty --only" (no pathspec) with dirty index
ought to be an acceptable way to create a new commit that does not
change any paths, but it was forbidden, perhaps because nobody
needed it so far.
- (merge beb635ca9c ak/commit-only-allow-empty later to maint).
* Git 2.11 had a minor regression in "merge --ff-only" that competed
with another process that simultanously attempted to update the
* A pathname that begins with "//" or "\\" on Windows is special but
path normalization logic was unaware of it.
- (merge 7814fbe3f1 js/normalize-path-copy-ceil later to maint).
* "git pull --rebase", when there is no new commits on our side since
we forked from the upstream, should be able to fast-forward without
invoking "git rebase", but it didn't.
- (merge 33b842a1e9 jc/pull-rebase-ff later to maint).
* The way to specify hotkeys to "xxdiff" that is used by "git
mergetool" has been modernized to match recent versions of xxdiff.
- (merge 6cf5f6cef7 da/mergetool-xxdiff-hotkey later to maint).
* Unlike "git am --abort", "git cherry-pick --abort" moved HEAD back
to where cherry-pick started while picking multiple changes, when
the cherry-pick stopped to ask for help from the user, and the user
did "git reset --hard" to a different commit in order to re-attempt
the operation.
- (merge ce73bb22d8 sb/sequencer-abort-safety later to maint).
* Code cleanup in shallow boundary computation.
- (merge 649b0c316a nd/shallow-fixup later to maint).
* A recent update to receive-pack to make it easier to drop garbage
objects made it clear that GIT_ALTERNATE_OBJECT_DIRECTORIES cannot
made it impossible to push into a repository at such a path. This
has been fixed by introducing a quoting mechanism used when
appending such a path to the colon-separated list.
- (merge 5e74824fac jk/quote-env-path-list-component later to maint).
* The function usage_msg_opt() has been updated to say "fatal:"
before the custom message programs give, when they want to die
with a message about wrong command line options followed by the
standard usage string.
- (merge 87433261a4 jk/parseopt-usage-msg-opt later to maint).
* "git index-pack --stdin" needs an access to an existing repository,
but "git index-pack file.pack" to generate an .idx file that
corresponds to a packfile does not.
- (merge 29401e1575 jk/index-pack-wo-repo-from-stdin later to maint).
* Fix for NDEBUG builds.
- (merge 08414938a2 jt/mailinfo-fold-in-body-headers later to maint).
* A lazy "git push" without refspec did not internally use a fully
specified refspec to perform 'current', 'simple', or 'upstream'
push, causing unnecessary "ambiguous ref" errors.
- (merge b284495e93 jc/push-default-explicit later to maint).
* "git p4" misbehaved when swapping a directory and a symbolic link.
- (merge df8a9e86db ld/p4-compare-dir-vs-symlink later to maint).
* Even though an fix was attempted in Git 2.9.3 days, but running
"git difftool --dir-diff" from a subdirectory never worked. This
has been fixed.
- (merge ce6926974e jk/difftool-in-subdir later to maint).
* "git p4" that tracks multile p4 paths imported a single changelist
that touches files in these multiple paths as one commit, followed
by many empty commits. This has been fixed.
- (merge 9943e5b979 gv/p4-multi-path-commit-fix later to maint).
* A potential but unlikely buffer overflow in Windows port has been
fixed.
- (merge c46458e82f mk/mingw-winansi-ttyname-termination-fix later to maint).
+
+ * When the http server gives an incomplete response to a smart-http
+ rpc call, it could lead to client waiting for a full response that
+ will never come. Teach the client side to notice this condition
+ and abort the transfer.
+
+ * Compression setting for producing packfiles were spread across
+ three codepaths, one of which did not honor any configuration.
+ Unify these so that all of them honor core.compression and
+ pack.compression variables the same way.
+
+ * "git fast-import" sometimes mishandled while rebalancing notes
+ tree, which has been fixed.
+
+ * Recent update to the default abbreviation length that auto-scales
+ lacked documentation update, which has been corrected.
+
+ * Leakage of lockfiles in the config subsystem has been fixed.
+
+ * It is natural that "git gc --auto" may not attempt to pack
+ everything into a single pack, and there is no point in warning
+ when the user has configured the system to use the pack bitmap,
+ leading to disabling further "gc".
+
+ * "git archive" did not read the standard configuration files, and
+ failed to notice a file that is marked as binary via the userdiff
+ driver configuration.
+
+ * "git blame --porcelain" misidentified the "previous" <commit, path>
+ pair (aka "source") when contents came from two or more files.
+
+ * "git rebase -i" with a recent update started showing an incorrect
+ count when squashing more than 10 commits.
+
+ * "git <cmd> @{push}" on a detached HEAD used to segfault; it has
+ been corrected to error out with a message.
+
+ * Running "git add a/b" when "a" is a submodule correctly errored
+ out, but without a meaningful error message.
+ (merge 2d81c48fa7 sb/pathspec-errors later to maint).
+
+ * Typing ^C to pager, which usually does not kill it, killed Git and
+ took the pager down as a collateral damage in certain process-tree
+ structure. This has been fixed.
+
+ * "git mergetool" without any pathspec on the command line that is
+ run from a subdirectory became no-op in Git v2.11 by mistake, which
+ has been fixed.
+
+ * Retire long unused/unmaintained gitview from the contrib/ area.
+ (merge 3120925c25 sb/remove-gitview later to maint).
+
+ * Tighten a test to avoid mistaking an extended ERE regexp engine as
+ a PRE regexp engine.
+
+ * An error message with an ASCII control character like '\r' in it
+ can alter the message to hide its early part, which is problematic
+ when a remote side gives such an error message that the local side
+ will relay with a "remote: " prefix.
+ (merge f290089879 jk/vreport-sanitize later to maint).
+
+ * "git fsck" inspects loose objects more carefully now.
+ (merge cce044df7f jk/loose-object-fsck later to maint).
+
+ * A crashing bug introduced in v2.11 timeframe has been found (it is
+ triggerable only in fast-import) and fixed.
+ (merge abd5a00268 jk/clear-delta-base-cache-fix later to maint).
+
+ * With an anticipatory tweak for remotes defined in ~/.gitconfig
+ (e.g. "remote.origin.prune" set to true, even though there may or
+ may not actually be "origin" remote defined in a particular Git
+ repository), "git remote rename" and other commands misinterpreted
+ and behaved as if such a non-existing remote actually existed.
+ (merge e459b073fb js/remote-rename-with-half-configured-remote later to maint).
+
+ * A few codepaths had to rely on a global variable when sorting
+ elements of an array because sort(3) API does not allow extra data
+ to be passed to the comparison function. Use qsort_s() when
+ natively available, and a fallback implementation of it when not,
+ to eliminate the need, which is a prerequisite for making the
+ codepath reentrant.
+
+ * "git fsck --connectivity-check" was not working at all.
+ (merge a2b22854bd jk/fsck-connectivity-check-fix later to maint).
+
+ * After starting "git rebase -i", which first opens the user's editor
+ to edit the series of patches to apply, but before saving the
+ contents of that file, "git status" failed to show the current
+ state (i.e. you are in an interactive rebase session, but you have
+ applied no steps yet) correctly.
+ (merge df9ded4984 js/status-pre-rebase-i later to maint).
+
+ * Test tweak for FreeBSD where /usr/bin/unzip is unsuitable to run
+ our tests but /usr/local/bin/unzip is usable.
+ (merge d98b2c5fce js/unzip-in-usr-bin-workaround later to maint).
+
+ * "git p4" did not work well with multiple git-p4.mapUser entries on
+ Windows.
+ (merge c3c2b05776 gv/mingw-p4-mapuser later to maint).
+
+ * "git help" enumerates executable files in $PATH; the implementation
+ of "is this file executable?" on Windows has been optimized.
+ (merge c755015f79 hv/mingw-help-is-executable later to maint).
+
+ * Test tweaks for those who have default ACL in their git source tree
+ that interfere with the umask test.
+ (merge d549d21307 mm/reset-facl-before-umask-test later to maint).
+
+ * Names of the various hook scripts must be spelled exactly, but on
+ Windows, an .exe binary must be named with .exe suffix; notice
+ $GIT_DIR/hooks/<hookname>.exe as a valid <hookname> hook.
+ (merge 235be51fbe js/mingw-hooks-with-exe-suffix later to maint).
+
+ * Asciidoctor, an alternative reimplementation of AsciiDoc, still
+ needs some changes to work with documents meant to be formatted
+ with AsciiDoc. "make USE_ASCIIDOCTOR=YesPlease" to use it out of
+ the box to document our pages is getting closer to reality.
+
+ * Correct command line completion (in contrib/) on "git svn"
+ (merge 2cbad17642 ew/complete-svn-authorship-options later to maint).
+
+ * Incorrect usage help message for "git worktree prune" has been fixed.
+ (merge 2488dcab22 ps/worktree-prune-help-fix later to maint).
+
+ * Adjust a perf test to new world order where commands that do
+ require a repository are really strict about having a repository.
+ (merge c86000c1a7 rs/p5302-create-repositories-before-tests later to maint).
+
+ * "git log --graph" did not work well with "--name-only", even though
+ other forms of "diff" output were handled correctly.
+ (merge f5022b5fed jk/log-graph-name-only later to maint).
+
+ * The push-options given via the "--push-options" option were not
+ passed through to external remote helpers such as "smart HTTP" that
+ are invoked via the transport helper.
+
+ * The documentation explained what "git stash" does to the working
+ tree (after stashing away the local changes) in terms of "reset
+ --hard", which was exposing an unnecessary implementation detail.
+ (merge 20a7e06172 tg/stash-doc-cleanup later to maint).
+
+ * When "git p4" imports changelist that removes paths, it failed to
+ convert pathnames when the p4 used encoding different from the one
+ used on the Git side. This has been corrected.
+ (merge a8b05162e8 ls/p4-path-encoding later to maint).
+
+ * A new coccinelle rule that catches a check of !pointer before the
+ pointer is free(3)d, which most likely is a bug.
+ (merge ec6cd14c7a rs/cocci-check-free-only-null later to maint).
+
+ * "ls-files" run with pathspec has been micro-optimized to avoid
+ having to memmove(3) unnecessary bytes.
+ (merge 96f6d3f61a rs/ls-files-partial-optim later to maint).
+
+ * A hotfix for a topic already in 'master'.
