  * "git stash save" has been deprecated in favour of "git stash push".
 
+ * The set of paths output from "git status --ignored" was tied
+   closely with its "--untracked=<mode>" option, but now it can be
+   controlled more flexibly.  Most notably, a directory that is
+   ignored because it is listed to be ignored in the ignore/exclude
+   mechanism can be handled differently from a directory that ends up
+   to be ignored only because all files in it are ignored.
+
+ * The remote-helper for talking to MediaWiki has been updated to
+   truncate an overlong pagename so that ".mw" suffix can still be
+   added.
+
+ * The remote-helper for talking to MediaWiki has been updated to

+
+ * The "--format=..." option "git for-each-ref" takes learned to show
+   the name of the 'remote' repository and the ref at the remote side
+   that is affected for 'upstream' and 'push' via "%(push:remotename)"
+   and friends.
+
+ * Doc and message updates to teach users "bisect view" is a synonym
+   for "bisect visualize".
+
+ * "git bisect run" that did not specify any command to run used to go
+   ahead and treated all commits to be tested as 'good'.  This has
+   been corrected by making the command error out.
+
+ * The SubmittingPatches document has been converted to produce an
+   HTML version via AsciiDoc/Asciidoctor.

    "auto" for coloured output configuration, i.e. either the standard

    latter, which has been fixed.

  * 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.

  * "git commit", after making a commit, did not check for errors when
    asking on what branch it made the commit, which has been correted.

  * "git status --ignored -u" did not stop at a working tree of a
    separate project that is embedded in an ignored directory and
    listed files in that other project, instead of just showing the
    directory itself as ignored.

  * A broken access to object databases in recent update to "git grep
    --recurse-submodules" has been fixed.

  * A recent regression in "git rebase -i" that broke execution of git
    commands from subdirectories via "exec" insn has been fixed.

  * A (possibly flakey) test fix.

  * "git check-ref-format --branch @{-1}" bit a "BUG()" when run
    outside a repository for obvious reasons; clarify the documentation
    and make sure we do not even try to expand the at-mark magic in
    such a case, but still call the validation logic for branch names.
-   (merge 89dd32aedc jc/check-ref-format-oor later to maint).
 
  * "git fetch --recurse-submodules" now knows that submodules can be
    moved around in the superproject in addition to getting updated,
    and finds the ones that need to be fetched accordingly.

    configuration variables have been added to "git config --help".

  * After an error from lstat(), diff_populate_filespec() function
    sometimes still went ahead and used invalid data in struct stat,
    which has been fixed.

  * UNC paths are also relevant in Cygwin builds and they are now
    tested just like Mingw builds.

  * Correct start-up sequence so that a repository could be placed
    immediately under the root directory again (which was broken at
    around Git 2.13).

  * The credential helper for libsecret (in contrib/) has been improved
    to allow possibly prompting the end user to unlock secrets that are
    currently locked (otherwise the secrets may not be loaded).
