the callers to tell the case where there was no new commits to
rewrite from other error cases.
+ * When built with more recent cURL, GIT_SSL_VERSION can now specify
+ "tlsv1.3" as its value.
+
+ * "git gui" learned that "~/.ssh/id_ecdsa.pub" and
+ "~/.ssh/id_ed25519.pub" are also possible SSH key files.
+ (merge 2e2f0288ef bb/git-gui-ssh-key-files later to maint).
+
+ * "git gui" performs commit upon CTRL/CMD+ENTER but the
+ CTRL/CMD+KP_ENTER (i.e. enter key on the numpad) did not have the
+ same key binding. It now does.
+ (merge 28a1d94a06 bp/git-gui-bind-kp-enter later to maint).
+
+ * "git gui" has been taught to work with old versions of tk (like
+ 8.5.7) that do not support "ttk::style theme use" as a way to query
+ the current theme.
+ (merge 4891961105 cb/git-gui-ttk-style later to maint).
+
+ * "git rebase" has learned to honor "--signoff" option when using
+ backends other than "am" (but not "--preserve-merges").
+
+ * "git branch --list" during an interrupted "rebase -i" now lets
+ users distinguish the case where a detached HEAD is being rebased
+ and a normal branch is being rebased.
+
+ * "git mergetools" learned talking to guiffy.
+
+ * The scripts in contrib/emacs/ have outlived their usefulness and
+ have been replaced with a stub that errors out and tells the user
+ there are replacements.
+
+ * The new "checkout-encoding" attribute can ask Git to convert the
+ contents to the specified encoding when checking out to the working
+ tree (and the other way around when checking in).
+
+ * The "git config" command uses separate options e.g. "--int",
+ "--bool", etc. to specify what type the caller wants the value to
+ be interpreted as. A new "--type=<typename>" option has been
+ introduced, which would make it cleaner to define new types.
+
+ * "git config --get" learned the "--default" option, to help the
+ calling script. Building on top of the above changes, the
+ "git config" learns "--type=color" type. Taken together, you can
+ do things like "git config --get foo.color --default blue" and get
+ the ANSI color sequence for the color given to foo.color variable,
+ or "blue" if the variable does not exist.
+
+ * "git ls-remote" learned an option to allow sorting its output based
+ on the refnames being shown.
+
+ * The command line completion (in contrib/) has been taught that "git
+ stash save" has been deprecated ("git stash push" is the preferred
+ spelling in the new world) and does not offer it as a possible
+ completion candidate when "git stash push" can be.
+
+ * "git gc --prune=nonsense" spent long time repacking and then
+ silently failed when underlying "git prune --expire=nonsense"
+ failed to parse its command line. This has been corrected.
+
+ * Error messages from "git push" can be painted for more visibility.
+
+ * "git http-fetch" (deprecated) had an optional and experimental
+ "feature" to fetch only commits and/or trees, which nobody used.
+ This has been removed.
Performance, Internal Implementation, Development Support etc.
* The mechanism to use parse-options API to automate the command line
completion continues to get extended and polished.
+ * Copies of old scripted Porcelain commands in contrib/examples/ have
+ been removed.
+
+ * Some tests that rely on the exact hardcoded values of object names
+ have been updated in preparation for hash function migration.
+
+ * Perf-test update.
+
+ * Test helper update.
+
+ * The effort continues to refactor the internal global data structure
+ to make it possible to open multiple repositories, work with and
+ then close them,
+
+ * Small test-helper programs have been consolidated into a single
+ binary.
+
+ * API clean-up around ref-filter code.
+
+ * Shell completion (in contrib) that gives list of paths have been
+ optimized somewhat.
+
+ * The index file is updated to record the fsmonitor section after a
+ full scan was made, to avoid wasting the effort that has already
+ spent.
+
+ * Performance measuring framework in t/perf learned to help bisecting
+ performance regressions.
+
+ * Some multi-word source filenames are being renamed to separate
+ words with dashes instead of underscores.
+
+ * An reusable "memory pool" implementation has been extracted from
+ fast-import.c, which in turn has become the first user of the
+ mem-pool API.
+
+ * A build-time option has been added to allow Git to be told to refer
+ to its associated files relative to the main binary, in the same
+ way that has been possible on Windows for quite some time, for
+ Linux, BSDs and Darwin.
+
+ * Precompute and store information necessary for ancestry traversal
+ in a separate file to optimize graph walking.
+
+ * The effort to pass the repository in-core structure throughout the
+ API continues. This round deals with the code that implements the
+ refs/replace/ mechanism.
+
+ * The build procedure "make DEVELOPER=YesPlease" learned to enable a
+ bit more warning options depending on the compiler used to help
+ developers more. There also is "make DEVOPTS=tokens" knob
+ available now, for those who want to help fixing warnings we
+ usually ignore, for example.
+
+ * A new version of the transport protocol is being worked on.
+
+ * The code to interface to GPG has been restructured somewhat to make
+ it cleaner to integrate with other types of signature systems later.
+
+
Also contains various documentation updates and code clean-ups.

+ * "git submodule status" misbehaved on a submodule that has been
+ removed from the working tree.
+ (merge 74b6bda32f rs/status-with-removed-submodule later to maint).
+
+ * When credential helper exits very quickly without reading its
+ input, it used to cause Git to die with SIGPIPE, which has been
+ fixed.
+ (merge a0d51e8d0e eb/cred-helper-ignore-sigpipe later to maint).
+
+ * "git rebase --keep-empty" still removed an empty commit if the
+ other side contained an empty commit (due to the "does an
+ equivalent patch exist already?" check), which has been corrected.
+ (merge 3d946165e1 pw/rebase-keep-empty-fixes later to maint).
+
+ * Some codepaths, including the refs API, get and keep relative
+ paths, that go out of sync when the process does chdir(2). The
+ chdir-notify API is introduced to let these codepaths adjust these
+ cached paths to the new current directory.
+ (merge fb9c2d2703 jk/relative-directory-fix later to maint).

+ * "cd sub/dir && git commit ../path" ought to record the changes to

+
+ * Small fix to the autoconf build procedure.
+ (merge 249482daf0 es/fread-reads-dir-autoconf-fix later to maint).
+
+ * Fix an unexploitable (because the oversized contents are not under
+ attacker's control) buffer overflow.
+ (merge d8579accfa bp/fsmonitor-bufsize-fix later to maint).
+
+ * Recent simplification of build procedure forgot a bit of tweak to
+ the build procedure of contrib/mw-to-git/
+ (merge d8698987f3 ab/simplify-perl-makefile later to maint).
+
+ * Moving a submodule that itself has submodule in it with "git mv"
+ forgot to make necessary adjustment to the nested sub-submodules;
+ now the codepath learned to recurse into the submodules.
+
+ * "git config --unset a.b", when "a.b" is the last variable in an
+ otherwise empty section "a", left an empty section "a" behind, and
+ worse yet, a subsequent "git config a.c value" did not reuse that
+ empty shell and instead created a new one. These have been
+ (partially) corrected.
+ (merge c71d8bb38a js/empty-config-section-fix later to maint).
+
+ * "git worktree remove" learned that "-f" is a shorthand for
+ "--force" option, just like for "git worktree add".
+ (merge d228eea514 sb/worktree-remove-opt-force later to maint).
+
+ * The completion script (in contrib/) learned to clear cached list of
+ command line options upon dot-sourcing it again in a more efficient
+ way.
+ (merge 94408dc71c sg/completion-clear-cached later to maint).
+
+ * "git svn" had a minor thinko/typo which has been fixed.
+ (merge 51db271587 ab/git-svn-get-record-typofix later to maint).
+
+ * During a "rebase -i" session, the code could give older timestamp
+ to commits created by later "pick" than an earlier "reword", which
+ has been corrected.
+ (merge 12f7babd6b js/ident-date-fix later to maint).
+
+ * "git submodule status" did not check the symbolic revision name it
+ computed for the submodule HEAD is not the NULL, and threw it at
+ printf routines, which has been corrected.
+ (merge 0b5e2ea7cf nd/submodule-status-fix later to maint).
+
+ * When fed input that already has In-Reply-To: and/or References:
+ headers and told to add the same information, "git send-email"
+ added these headers separately, instead of appending to an existing
+ one, which is a violation of the RFC. This has been corrected.
+ (merge 256be1d3f0 sa/send-email-dedup-some-headers later to maint).
+
+ * "git fast-export" had a regression in v2.15.0 era where it skipped
+ some merge commits in certain cases, which has been corrected.
+ (merge be011bbe00 ma/fast-export-skip-merge-fix later to maint).

* Other minor doc, test and build updates and code cleanups.
