+Git v2.9.3 Release Notes
+========================
+
+Fixes since v2.9.2
+------------------
+
+ * A helper function that takes the contents of a commit object and
+   finds its subject line did not ignore leading blank lines, as is
+   commonly done by other codepaths.  Make it ignore leading blank
+   lines to match.
+
+ * Git does not know what the contents in the index should be for a
+   path added with "git add -N" yet, so "git grep --cached" should not
+   show hits (or show lack of hits, with -L) in such a path, but that
+   logic does not apply to "git grep", i.e. searching in the working
+   tree files.  But we did so by mistake, which has been corrected.
+
+ * "git rebase -i --autostash" did not restore the auto-stashed change
+   when the operation was aborted.
+
+ * "git commit --amend --allow-empty-message -S" for a commit without
+   any message body could have misidentified where the header of the
+   commit object ends.
+
+ * More mark-up updates to typeset strings that are expected to
+   literally typed by the end user in fixed-width font.
+
+ * For a long time, we carried an in-code comment that said our
+   colored output would work only when we use fprintf/fputs on
+   Windows, which no longer is the case for the past few years.
+
+ * "gc.autoPackLimit" when set to 1 should not trigger a repacking
+   when there is only one pack, but the code counted poorly and did
+   so.
+
+ * One part of "git am" had an oddball helper function that called
+   stuff from outside "his" as opposed to calling what we have "ours",
+   which was not gender-neutral and also inconsistent with the rest of
+   the system where outside stuff is usually called "theirs" in
+   contrast to "ours".
+
+ * The test framework learned a new helper test_match_signal to
+   check an exit code from getting killed by an expected signal.
+
+ * "git blame -M" missed a single line that was moved within the file.
+
+ * Fix recently introduced codepaths that are involved in parallel
+   submodule operations, which gave up on reading too early, and
+   could have wasted CPU while attempting to write under a corner
+   case condition.
+
+ * "git grep -i" has been taught to fold case in non-ascii locales
+   correctly.
+
+ * A test that unconditionally used "mktemp" learned that the command
+   is not necessarily available everywhere.
+
+ * "git blame file" allowed the lineage of lines in the uncommitted,
+   unadded contents of "file" to be inspected, but it refused when
+   "file" did not appear in the current commit.  When "file" was
+   created by renaming an existing file (but the change has not been
+   committed), this restriction was unnecessarily tight.
+
+ * "git add -N dir/file && git write-tree" produced an incorrect tree
+   when there are other paths in the same directory that sorts after
+   "file".
+
+ * "git fetch http://user:pass@host/repo..." scrubbed the userinfo
+   part, but "git push" didn't.
+
+ * An age old bug that caused "git diff --ignore-space-at-eol"
+   misbehave has been fixed.
+
+ * "git notes merge" had a code to see if a path exists (and fails if
+   it does) and then open the path for writing (when it doesn't).
+   Replace it with open with O_EXCL.
+
+ * "git pack-objects" and "git index-pack" mostly operate with off_t
+   when talking about the offset of objects in a packfile, but there
+   were a handful of places that used "unsigned long" to hold that
+   value, leading to an unintended truncation.
+
+ * Recent update to "git daemon" tries to enable the socket-level
+   KEEPALIVE, but when it is spawned via inetd, the standard input
+   file descriptor may not necessarily be connected to a socket.
+   Suppress an ENOTSOCK error from setsockopt().
+
+ * Recent FreeBSD stopped making perl available at /usr/bin/perl;
+   switch the default the built-in path to /usr/local/bin/perl on not
+   too ancient FreeBSD releases.
+
+ * "git status" learned to suggest "merge --abort" during a conflicted
+   merge, just like it already suggests "rebase --abort" during a
+   conflicted rebase.
+
+ * The .c/.h sources are marked as such in our .gitattributes file so
+   that "git diff -W" and friends would work better.
+
+ * Existing autoconf generated test for the need to link with pthread
+   library did not check all the functions from pthread libraries;
+   recent FreeBSD has some functions in libc but not others, and we
+   mistakenly thought linking with libc is enough when it is not.
+
+ * Allow http daemon tests in Travis CI tests.
+
+ * Users of the parse_options_concat() API function need to allocate
+   extra slots in advance and fill them with OPT_END() when they want
+   to decide the set of supported options dynamically, which makes the
+   code error-prone and hard to read.  This has been corrected by tweaking
+   the API to allocate and return a new copy of "struct option" array.
+
+ * The use of strbuf in "git rm" to build filename to remove was a bit
+   suboptimal, which has been fixed.
+
+ * "git commit --help" said "--no-verify" is only about skipping the
+   pre-commit hook, and failed to say that it also skipped the
+   commit-msg hook.
+
+ * "git merge" in Git v2.9 was taught to forbid merging an unrelated
+   lines of history by default, but that is exactly the kind of thing
+   the "--rejoin" mode of "git subtree" (in contrib/) wants to do.
+   "git subtree" has been taught to use the "--allow-unrelated-histories"
+   option to override the default.
+
+ * The build procedure for "git persistent-https" helper (in contrib/)
+   has been updated so that it can be built with more recent versions
+   of Go.
+
+ * There is an optimization used in "git diff $treeA $treeB" to borrow
+   an already checked-out copy in the working tree when it is known to
+   be the same as the blob being compared, expecting that open/mmap of
+   such a file is faster than reading it from the object store, which
+   involves inflating and applying delta.  This however kicked in even
+   when the checked-out copy needs to go through the convert-to-git
+   conversion (including the clean filter), which defeats the whole
+   point of the optimization.  The optimization has been disabled when
+   the conversion is necessary.
+
+ * "git -c grep.patternType=extended log --basic-regexp" misbehaved
+   because the internal API to access the grep machinery was not
+   designed well.
+
+ * Windows port was failing some tests in t4130, due to the lack of
+   inum in the returned values by its lstat(2) emulation.
+
+ * The characters in the label shown for tags/refs for commits in
+   "gitweb" output are now properly escaped for proper HTML output.
+
+ * FreeBSD can lie when asked mtime of a directory, which made the
+   untracked cache code to fall back to a slow-path, which in turn
+   caused tests in t7063 to fail because it wanted to verify the
+   behaviour of the fast-path.
+
+ * Squelch compiler warnings for netmalloc (in compat/) library.
+
+ * The API documentation for hashmap was unclear if hashmap_entry
+   can be safely discarded without any other consideration.  State
+   that it is safe to do so.
+
+ * Not-so-recent rewrite of "git am" that started making internal
+   calls into the commit machinery had an unintended regression, in
+   that no matter how many seconds it took to apply many patches, the
+   resulting committer timestamp for the resulting commits were all
+   the same.
+
+ * "git difftool <paths>..." started in a subdirectory failed to
+   interpret the paths relative to that directory, which has been
+   fixed.
+
+Also contains minor documentation updates and code clean-ups.
