---------------------------------
This release has a few changes in the user-visible output from
-Porcelain commands, which the users may want to be aware of.
+Porcelain commands. These are not meant to be parsed by scripts, but
+the users still may want to be aware of the changes:
* Output from "git log --decorate" (and "%d" format specifier used in
the userformat "--format=<string>" parameter "git log" family of
* A new "push.followTags" configuration turns the "--follow-tags"
option on by default for the "git push" command.
+ * "git log --graph --no-walk A B..." is a conflicting request that
+ asks nonsense; no-walk tells us show discrete points in the
+ history, while graph asks to draw connections between these
+ discrete points. Forbid the combination.
+
+ * "git rev-list --bisect --first-parent" does not work (yet) and can
+ even cause SEGV; forbid it. "git log --bisect --first-parent"
+ would not be useful until "git bisect --first-parent" materializes,
+ so it is also forbidden for now.
+
Performance, Internal Implementation, Development Support etc.
* "git push" codepath has been restructured to make it easier to add
new configuration bits.
+ * The run-command interface was easy to abuse and make a pipe for us
+ to read from the process, wait for the process to finish and then
+ attempt to read its output, which is a pattern that lead to a
+ deadlock. Fix such uses by introducing a helper to do this
+ correctly (i.e. we need to read first and then wait the process to
+ finish) and also add code to prevent such abuse in the run-command
+ helper.
+
+ * People often forget to chain the commands in their test together
+ with &&, leaving a failure from an earlier command in the test go
+ unnoticed. The new GIT_TEST_CHAIN_LINT mechanism allows you to
+ catch such a mistake more easily.
+
Also contains various documentation updates and code clean-ups.

a user name with an at-sign in it.
(merge 13d261e av/wincred-with-at-in-username-fix later to maint).
+ * "diff-highlight" (in contrib/) used to show byte-by-byte
+ differences, which meant that multi-byte characters can be chopped
+ in the middle. It learned to pay attention to character boundaries
+ (assuming the UTF-8 payload).
+ (merge 8d00662 jk/colors later to maint).
+
+ * "git merge --quiet" did not squelch messages from the underlying
+ merge-recursive strategy.
+ (merge 2bf15a3 jk/merge-quiet later to maint).
+
* Longstanding configuration variable naming rules has been added to
the documentation.

* We did not parse username followed by literal IPv6 address in SSH
transport URLs, e.g. ssh://user@[2001:db8::1]:22/repo.git
correctly.

+ * "git prune" used to largely ignore broken refs when deciding which
+ objects are still being used, which could spread an existing small
+ damage and make it a larger one.
+ (merge ea56c4e jk/prune-with-corrupt-refs later to maint).
+
+ * The split-index mode introduced at v2.3.0-rc0~41 was broken in the
+ codepath to protect us against a broken reimplementation of Git
+ that writes an invalid index with duplicated index entries, etc.
+ (merge 03f15a7 tg/fix-check-order-with-split-index later to maint).
+
+ * "git fetch" that fetches a commit using the allow-tip-sha1-in-want
+ extension could have failed to fetch all the requested refs.
+ (merge 32d0462 jk/fetch-pack later to maint).
+
+ * An failure early in the "git clone" that started creating the
+ working tree and repository could have resulted in some directories
+ and files left without getting cleaned up.
+ (merge 16eff6c jk/cleanup-failed-clone later to maint).
+
+ * Recommend format-patch and send-email for those who want to submit
+ patches to this project.
+ (merge b25c469 jc/submitting-patches-mention-send-email later to maint).
+
+ * Even though "git grep --quiet" is run merely to ask for the exit
+ status, we spawned the pager regardless. Stop doing that.

+
+ * The prompt script (in contrib/) did not show the untracked sign
+ when working in a subdirectory without any untracked files.

+
* Code cleanups and documentation updates.
