+Git 2.16 Release Notes
+======================
+
+Backward compatibility notes and other notable changes.
+
+ * Use of an empty string as a pathspec element that is used for
+   'everything matches' is now an error.
+
+
+Updates since v2.15
+-------------------
+
+UI, Workflows & Features
+
+ * An empty string as a pathspec element that means "everything"
+   i.e. 'git add ""', is now illegal.  We started this by first
+   deprecating and warning a pathspec that has such an element in
+   2.11 (Nov 2016).
+
+ * A hook script that is set unexecutable is simply ignored.  Git
+   notifies when such a file is ignored, unless the message is
+   squelched via advice.ignoredHook configuration.
+
+ * "git pull" has been taught to accept "--[no-]signoff" option and
+   pass it down to "git merge".
+
+ * The "--push-option=<string>" option to "git push" now defaults to a
+   list of strings configured via push.pushOption variable.
+
+ * "gitweb" checks if a directory is searchable with Perl's "-x"
+   operator, which can be enhanced by using "filetest 'access'"
+   pragma, which now we do.
+
+ * "git stash save" has been deprecated in favour of "git stash push".
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * An earlier update made it possible to use an on-stack in-core
+   lockfile structure (as opposed to having to deliberately leak an
+   on-heap one).  Many codepaths have been updated to take advantage
+   of this new facility.
+
+ * Calling cmd_foo() as if it is a general purpose helper function is
+   a no-no.  Correct two instances of such to set an example.
+
+ * We try to see if somebody runs our test suite with a shell that
+   does not support "local" like bash/dash does.
+
+ * An early part of piece-by-piece rewrite of "git bisect" in C.
+
+ * GSoC to piece-by-piece rewrite "git submodule" in C.
+
+ * Optimize the code to find shortest unique prefix of object names.
+
+ * Pathspec-limited revision traversal was taught not to keep finding
+   unneeded differences once it knows two trees are different inside
+   given pathspec.
+
+ * Conversion from uchar[20] to struct object_id continues.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.15
+-----------------
+
+ * "auto" as a value for the columnar output configuration ought to
+   judge "is the output consumed by humans?" with the same criteria as
+   "auto" for coloured output configuration, i.e. either the standard
+   output stream is going to tty, or a pager is in use.  We forgot the
+   latter, which has been fixed.
+   (merge 965ff23a43 kd/auto-col-with-pager-fix later to maint).
+
+ * The experimental "color moved lines differently in diff output"
+   feature was buggy around "ignore whitespace changes" edges, whihch
+   has been corrected.
+   (merge b66b507292 jk/diff-color-moved-fix later to maint).
+
+ * Instead of using custom line comparison and hashing functions to
+   implement "moved lines" coloring in the diff output, use the pair
+   of these functions from lower-layer xdiff/ code.
+   (merge 01be97c2b2 sb/diff-color-moved-use-xdl-recmatch later to maint).
+
+ * Some codepaths did not check for errors when asking what branch the
+   HEAD points at, which have been fixed.
+   (merge dbd2b55cb7 jk/misc-resolve-ref-unsafe-fixes later to maint).
+
+ * "git commit", after making a commit, did not check for errors when

+   (merge c26de08370 ao/check-resolve-ref-unsafe-result later to maint).
