UI, Workflows & Features
+ * The bash completion script (in contrib/) learned a few options that
+ "git revert" takes.
+
+ * Whitespace breakages in deleted and context lines can also be
+ painted in the output of "git diff" and friends with the new
+ --ws-error-highlight option.
+
* List of commands shown by "git help" are grouped along the workflow
elements to help early learners.
behaves as if HEAD:Documentation/RelNotes/2.5.0.txt was given as
input instead.
+ * "git send-email" learned the alias file format used by the sendmail
+ program (in an abbreviated form).
+
Performance, Internal Implementation, Development Support etc.
* for_each_ref() callback functions were taught to name the objects
not with "unsigned char sha1[20]" but with "struct object_id".
+ * Error reporting mechanism used in "refs" API has been made more
+ consistent.
+
+ * "git pull" has more test coverage now.
+
Also contains various documentation updates and code clean-ups.
* Memory usage of "git index-pack" has been trimmed by tens of
per-cent.

+ (merge a78c5b3 nd/slim-index-pack-memory-usage later to maint).
* "git rev-list --objects $old --not --all" to see if everything that
is reachable from $old is already connected to the existing refs
paths outside the given pathspec.
(merge 838d6a9 dt/clean-pathspec-filter-then-lstat later to maint).
+ * Recent "git prune" traverses young unreachable objects to safekeep
+ old objects in the reachability chain from them, which sometimes
+ caused error messages that are unnecessarily alarming.
+ (merge ce4e7b2 jk/squelch-missing-link-warning-for-unreachable later to maint).
+
+ * The configuration reader/writer uses mmap(2) interface to access
+ the files; when we find a directory, it barfed with "Out of memory?".
+ (merge 9ca0aaf jk/diagnose-config-mmap-failure later to maint).
+
+ * "color.diff.plain" was a misnomer; give it 'color.diff.context' as
+ a more logical synonym.
+ (merge 8dbf3eb jk/color-diff-plain-is-context later to maint).
+
+ * The setup code used to die when core.bare and core.worktree are set
+ inconsistently, even for commands that do not need working tree.
+ (merge fada767 jk/die-on-bogus-worktree-late later to maint).
+
* Code cleanups and documentation updates.
