UI, Workflows & Features
+ * "diff" family of commands learned "--find-object=<object-id>" option
+ to limit the findings to changes that involve the named object.
+ (merge 4d8c51aa19 sb/diff-blobfind-pickaxe later to maint).
+
Performance, Internal Implementation, Development Support etc.
+ * More perf tests for threaded grep
+ (merge 7b31b55db1 ab/perf-grep-threads later to maint).
+
+ * "perf" test output can be sent to codespeed server.
+ (merge 19cf57a92e cc/codespeed later to maint).
+
+ * The build procedure for perl/ part has been greatly simplified by
+ weaning ourselves off of MakeMaker.
+
+ * In preparation for implementing narrow/partial clone, the machinery
+ for checking object connectivity used by gc and fsck has been
+ taught that a missing object is OK when it is referenced by a
+ packfile specially marked as coming from trusted repository that
+ promises to make them available on-demand and lazily.
+
+ * The machinery to clone & fetch, which in turn involves packing and
+ unpacking objects, has been told how to omit certain objects using
+ the filtering mechanism introduced by another topic. It now knows
+ to mark the resulting pack as a promisor pack to tolerate missing
+ objects, laying foundation for "narrow" clones.
+
+ * The first step to getting rid of mru API and using the
+ doubly-linked list API directly instead.
+
+ * Retire mru API as it does not give enough abstraction over
+ underlying list API to be worth it.
+
+ * Rewrite two more "git submodule" subcommands in C.
+
+ * The tracing machinery learned to report tweaking of environment
+ variables as well.
+ (merge 090a09272a nd/trace-with-env later to maint).
+
+ * Update Coccinelle rules to catch and optimize strbuf_addf(&buf, "%s", str)
+ (merge cd9a4b6d93 rs/strbuf-cocci-workaround later to maint).
+
+ * Prevent "clang-format" from breaking line after function return type.
+ (merge a3715d43e8 po/clang-format-functype-weight later to maint).
+
+ * The sequencer infrastructure is shared across "git cherry-pick",
+ "git rebase -i", etc., and has always spawned "git commit" when it
+ needs to create a commit. It has been taught to do so internally,
+ when able, by reusing the codepath "git commit" itself uses, which
+ gives performance boost for a few tens of percents in some sample
+ scenarios.
+
Also contains various documentation updates and code clean-ups.
Fixes since v2.16
-----------------
+ * An old regression in "git describe --all $annotated_tag^0" has been
+ fixed.
+ (merge 1bba00130a dk/describe-all-output-fix later to maint).
+
+ * "git status" after moving a path in the working tree (hence making
+ it appear "removed") and then adding with the -N option (hence
+ making that appear "added") detected it as a rename, but did not
+ report the old and new pathnames correctly.
+ (merge 176ea74793 nd/ita-wt-renames-in-status later to maint).
+
+ * "git svn dcommit" did not take into account the fact that a
+ svn+ssh:// URL with a username@ (typically used for pushing) refers
+ to the same SVN repository without the username@ and failed when
+ svn.pushmergeinfo option is set.
+ (merge 8aaed892fd jm/svn-pushmergeinfo-fix later to maint).
+
+ * API clean-up around revision traversal.
+ (merge 6fcec2f9ae rs/lose-leak-pending later to maint).
+
+ * "git merge -Xours/-Xtheirs" learned to use our/their version when
+ resolving a conflicting updates to a symbolic link.
+ (merge fd48b46474 jc/merge-symlink-ours-theirs later to maint).
+
+ * "git clone $there $here" is allowed even when here directory exists
+ as long as it is an empty directory, but the command incorrectly
+ removed it upon a failure of the operation.
+ (merge d45420c1c8 jk/abort-clone-with-existing-dest later to maint).
+
+ * "git commit --fixup" did not allow "-m<message>" option to be used
+ at the same time; allow it to annotate resulting commit with more
+ text.
+ (merge 30884c9afc ab/commit-m-with-fixup later to maint).
+
+ * When resetting the working tree files recursively, the working tree
+ of submodules are now also reset to match.
+ (merge 7dcc1f4df8 sb/submodule-update-reset-fix later to maint).
+
+ * "git stash -- <pathspec>" incorrectly blew away untracked files in
+ the directory that matched the pathspec, which has been corrected.
+ (merge bba067d2fa tg/stash-with-pathspec-fix later to maint).
+
+ * Instead of maintaining home-grown email address parsing code, ship
+ a copy of reasonably recent Mail::Address to be used as a fallback
+ in 'git send-email' when the platform lacks it.
+ (merge d60be8acab mm/send-email-fallback-to-local-mail-address later to maint).
+
+ * "git add -p" was taught to ignore local changes to submodules as
+ they do not interfere with the partial addition of regular changes
+ anyway.
+ (merge 12434efc1d nd/add-i-ignore-submodules later to maint).
+
+ * Avoid showing a warning message in the middle of a line of "git
+ diff" output.
+ (merge 4e056c989f nd/diff-flush-before-warning later to maint).
+
+ * The http tracing code, often used to debug connection issues,
+ learned to redact potentially sensitive information from its output
+ so that it can be more safely sharable.
+ (merge 8ba18e6fa4 jt/http-redact-cookies later to maint).
+
+ * Crash fix for a corner case where an error codepath tried to unlock
+ what it did not acquire lock on.
+ (merge 81fcb698e0 mr/packed-ref-store-fix later to maint).
+
+ * The split-index mode had a few corner case bugs fixed.
+ (merge ae59a4e44f tg/split-index-fixes later to maint).
+
+ * Assorted fixes to "git daemon".
+ (merge ed15e58efe jk/daemon-fixes later to maint).
+
+ * Completion of "git merge -s<strategy>" (in contrib/) did not work
+ well in non-C locale.
+ (merge 7cc763aaa3 nd/list-merge-strategy later to maint).
+
+ * Workaround for segfault with more recent versions of SVN.
+ (merge 7f6f75e97a ew/svn-branch-segfault-fix later to maint).
+
* Other minor doc, test and build updates and code cleanups.
