to be used in a rare event that merges histories of two projects
that started their lives independently.
+ * "git pull" has been taught to pass --allow-unrelated-histories
+ option to underlying "git merge".
+
* "git apply -v" learned to report paths in the patch that were
skipped via --include/--exclude mechanism or being outside the
current working directory.
such a case, and allows the users to override it with a new option,
"--no-expand-tabs".
+ * "git send-email" now uses a more readable timestamps when
+ formulating a message ID.
+
+ * "git rerere" can encounter two or more files with the same conflict
+ signature that have to be resolved in different ways, but there was
+ no way to record these separate resolutions.
+ (merge 890fca8 jc/rerere-multi later to maint).
+
+ * "git p4" learned to record P4 jobs in Git commit that imports from
+ the history in Perforce.
+
+ * "git describe --contains" often made a hard-to-justify choice of
+ tag to give name to a given commit, because it tried to come up
+ with a name with smallest number of hops from a tag, causing an old
+ commit whose close descendant that is recently tagged were not
+ described with respect to an old tag but with a newer tag. It did
+ not help that its computation of "hop" count was further tweaked to
+ penalize being on a side branch of a merge. The logic has been
+ updated to favor using the tag with the oldest tagger date, which
+ is a lot easier to explain to the end users: "We describe a commit
+ in terms of the (chronologically) oldest tag that contains the
+ commit."
+ (merge 7550424 js/name-rev-use-oldest-ref later to maint).
+
+ * "git clone" learned "--shallow-submodules" option.
+
+ * HTTP transport clients learned to throw extra HTTP headers at the
+ server, specified via http.extraHeader configuration variable.
+
+ * Patch output from "git diff" and friends has been tweaked to be
+ more readable by using a blank line as a strong hint that the
+ contents before and after it belong to a logically separate unit.

Performance, Internal Implementation, Development Support etc.
* The embedded args argv-array in the child process is used to build
the command line to run pack-objects instead of using a separate
array of strings.

* A test for tags has been restructured so that more parts of it can
easily be run on a platform without a working GnuPG.

subcommand implementations, and Git avoids attempting to touch
references when we are not in a repository.

* The command line argument parser for "receive-pack" has been
rewritten to use parse-options.

* Rename bunch of tests on "git clone" for better organization.
- (merge 8fbb03a sb/clone-t57-t56 later to maint).
* The tests that involve running httpd leaked the system-wide
configuration in /etc/gitconfig to the tested environment.
- (merge 1fad503 jk/test-httpd-config-nosystem later to maint).
* Build updates for MSVC.
- (merge 0ef60af ss/msvc later to maint).
* The repository set-up sequence has been streamlined (the biggest
change is that there is no longer git_config_early()), so that we
do not attempt to look into refs/* when we know we do not have a
Git repository.
- (merge 274db84 jk/check-repository-format later to maint).
+
+ * Code restructuring around the "refs" area to prepare for pluggable
+ refs backends.
+
+ * Sources to many test helper binaries (and the generated helpers)
+ have been moved to t/helper/ subdirectory to reduce clutter at the
+ top level of the tree.
+
+ Note that this can break your tests if you check out revisions
+ across the merge boundary of this topic, e0b58519 (Merge branch
+ 'nd/test-helpers', 2016-04-29), as bin-wrappers/test-* are not
+ rebuilt to point the underlying executables. For now, "make
+ distclean" is your friend.
+
+ * Unify internal logic between "git tag -v" and "git verify-tag"
+ commands by making one directly call into the other.
+ (merge bef234b st/verify-tag later to maint).
+
+ * "merge-recursive" strategy incorrectly checked if a path that is
+ involved in its internal merge exists in the working tree.
+
+ * The test scripts for "git p4" (but not "git p4" implementation
+ itself) has been updated so that they would work even on a system
+ where the installed version of Python is python 3.
+ (merge 1fb3fb4 ld/p4-test-py3 later to maint).
+
+ * As nobody maintains our in-tree git.spec.in and distros use their
+ own spec file, we stopped pretending that we support "make rpm".
+
+ * Move from unsigned char[20] to struct object_id continues.
Also contains various documentation updates and code clean-ups.
* "git config --get-urlmatch", unlike other variants of the "git
config --get" family, did not signal error with its exit status
when there was no matching configuration.
- (merge 24990b2 jk/config-get-urlmatch later to maint).
* The "--local-env-vars" and "--resolve-git-dir" options of "git
rev-parse" failed to work outside a repository when the command's
option parsing was rewritten in 1.8.5 era.
- (merge fc7d47f jk/rev-parse-local-env-vars later to maint).
* "git index-pack --keep[=<msg>] pack-$name.pack" simply did not work.
- (merge 0e94242 jc/maint-index-pack-keep later to maint).
* Fetching of history by naming a commit object name directly didn't
work across remote-curl transport.
- (merge 754ecb1 gf/fetch-pack-direct-object-fetch later to maint).
* A small memory leak in an error codepath has been plugged in xdiff
code.
- (merge 87f1625 rj/xdiff-prepare-plug-leak-on-error-codepath later to maint).
* strbuf_getwholeline() did not NUL-terminate the buffer on certain
corner cases in its error codepath.
- (merge b709043 jk/getwholeline-getdelim-empty later to maint).
* "git mergetool" did not work well with conflicts that both sides
deleted.
- (merge a298604 da/mergetool-delete-delete-conflict later to maint).
* "git send-email" had trouble parsing alias file in mailrc format
when lines in it had trailing whitespaces on them.
- (merge a277d1e jk/send-email-rtrim-mailrc-alias later to maint).
* When "git merge --squash" stopped due to conflict, the concluding
"git commit" failed to read in the SQUASH_MSG that shows the log
messages from all the squashed commits.
- (merge b64c1e0 ss/commit-squash-msg later to maint).
* "git merge FETCH_HEAD" dereferenced NULL pointer when merging
nothing into an unborn history (which is arguably unusual usage,
which perhaps was the reason why nobody noticed it).
- (merge b84e65d jv/merge-nothing-into-void later to maint).
* When "git worktree" feature is in use, "git branch -d" allowed
deletion of a branch that is checked out in another worktree,
which was wrong.
- (merge f292244 ky/branch-d-worktree later to maint).
+
+ * When "git worktree" feature is in use, "git branch -m" renamed a
+ branch that is checked out in another worktree without adjusting
+ the HEAD symbolic ref for the worktree.
* "git diff -M" used to work better when two originally identical
files A and B got renamed to X/A and X/B by pairing A to X/A and B
to X/B, but this was broken in the 2.0 timeframe.
- (merge ca4e3ca sg/diff-multiple-identical-renames later to maint).
* "git send-pack --all <there>" was broken when its command line
option parsing was written in the 2.6 timeframe.
- (merge c677756 sk/send-pack-all-fix later to maint).
* "git format-patch --help" showed `-s` and `--no-patch` as if these
are valid options to the command. We already hide `--patch` option
from the documentation, because format-patch is about showing the
diff, and the documentation now hides these options as well.
- (merge b73a1bc es/format-patch-doc-hide-no-patch later to maint).
* When running "git blame $path" with unnormalized data in the index
for the path, the data in the working tree was blamed, even though
"git add" would not have changed what is already in the index, due
to "safe crlf" that disables the line-end conversion. It has been
corrected.
- (merge a08feb8 tb/blame-force-read-cache-to-workaround-safe-crlf later to maint).
+
+ * A change back in version 2.7 to "git branch" broke display of a
+ symbolic ref in a non-standard place in the refs/ hierarchy (we
+ expect symbolic refs to appear in refs/remotes/*/HEAD to point at
+ the primary branch the remote has, and as .git/HEAD to point at the
+ branch we locally checked out).
+
+ * A partial rewrite of "git submodule" in the 2.7 timeframe changed
+ the way the gitdir: pointer in the submodules point at the real
+ repository location to use absolute paths by accident. This has
+ been corrected.
+
+ * "git commit" misbehaved in a few minor ways when an empty message
+ is given via -m '', all of which has been corrected.
+
+ * Support for CRAM-MD5 authentication method in "git imap-send" did
+ not work well.
+
+ * Upcoming OpenSSL 1.1.0 will break compilation b updating a few APIs
+ we use in imap-send, which has been adjusted for the change.
+ (merge 1245c74 ky/imap-send-openssl-1.1.0 later to maint).
+
+ * The socks5:// proxy support added back in 2.6.4 days was not aware
+ that socks5h:// proxies behave differently.
+
+ * "git config" had a codepath that tried to pass a NULL to
+ printf("%s"), which nobody seems to have noticed.
+
+ * On Cygwin, object creation uses the "create a temporary and then
+ rename it to the final name" pattern, not "create a temporary,
+ hardlink it to the final name and then unlink the temporary"
+ pattern.
+
+ This is necessary to use Git on Windows shared directories, and is
+ already enabled for the MinGW and plain Windows builds. It also
+ has been used in Cygwin packaged versions of Git for quite a while.
+ See http://thread.gmane.org/gmane.comp.version-control.git/291853
+
+ * "merge-octopus" strategy did not ensure that the index is clean
+ when merge begins.
+
+ * When "git merge" notices that the merge can be resolved purely at
+ the tree level (without having to merge blobs) and the resulting
+ tree happens to already exist in the object store, it forgot to
+ update the index, which lead to an inconsistent state for later
+ operations.
+
+ * "git submodule" reports the paths of submodules the command
+ recurses into, but this was incorrect when the command was not run
+ from the root level of the superproject.
+ (merge 2ab5660 sb/submodule-path-misc-bugs later to maint).
+
+ * The "user.useConfigOnly" configuration variable makes it an error
+ if users do not explicitly set user.name and user.email. However,
+ its check was not done early enough and allowed another error to
+ trigger, reporting that the default value we guessed from the
+ system setting was unusable. This was a suboptimal end-user
+ experience as we want the users to set user.name/user.email without
+ relying on the auto-detection at all.
+ (merge d3c06c1 da/user-useconfigonly later to maint).
+
+ * "git mv old new" did not adjust the path for a submodule that lives
+ as a subdirectory inside old/ directory correctly.
+ (merge a127331 sb/mv-submodule-fix later to maint).
+
+ * "git replace -e" did not honour "core.editor" configuration.
+ (merge 36b1437 js/replace-edit-use-editor-configuration later to maint).
+
+ * "git push" from a corrupt repository that attempts to push a large
+ number of refs deadlocked; the thread to relay rejection notices
+ for these ref updates blocked on writing them to the main thread,
+ after the main thread at the receiving end notices that the push
+ failed and decides not to read these notices and return a failure.
+ (merge f924b52a jk/push-client-deadlock-fix later to maint).
+
+ * mmap emulation on Windows has been optimized and work better without
+ consuming paging store when not needed.
+ (merge d5425d1 js/win32-mmap later to maint).
+
+ * A question by "git send-email" to ask the identity of the sender
+ has been updated.
+ (merge 0d6b21e jd/send-email-to-whom later to maint).
+
+ * UI consistency improvements for "git mergetool".
+ (merge cce076e nf/mergetool-prompt later to maint).
+
+ * "git rebase -m" could be asked to rebase an entire branch starting
+ from the root, but failed by assuming that there always is a parent
+ commit to the first commit on the branch.
+ (merge 79f4344 bw/rebase-merge-entire-branch later to maint).
+
+ * Fix a broken "p4 lfs" test.
+ (merge 9e220fe ls/p4-lfs-test-fix-2.7.0 later to maint).
