+ * "git status" learned to pay attention to UI related diff
+ configuration variables such as diff.renames.

+ * The command line completion mechanism (in contrib/) learned to load
+ custom completion file for "git $command" where $command is a
+ custom "git-$command" that the end user has on the $PATH when using

* The code to interface to GPG has been restructured somewhat to make
it cleaner to integrate with other types of signature systems later.
+ * The code has been taught to use the duplicated information stored
+ in the commit-graph file to learn the tree object name for a commit
+ to avoid opening and parsing the commit object when it makes sense
+ to do so.
+
+ * "git gc" in a large repository takes a lot of time as it considers
+ to repack all objects into one pack by default. The command has
+ been taught to pretend as if the largest existing packfile is
+ marked with ".keep" so that it is left untouched while objects in
+ other packs and loose ones are repacked.
+
+ * The transport protocol v2 is getting updated further.
+
+ * The codepath around object-info API has been taught to take the
+ repository object (which in turn tells the API which object store
+ the objects are to be located).
+
+ * Rename detection logic in "diff" family that is used in "merge" has
+ learned to guess when all of x/a, x/b and x/c have moved to z/a,
+ z/b and z/c, it is likely that x/d added in the meantime would also
+ want to move to z/d by taking the hint that the entire directory
+ 'x' moved to 'z'. A bug causing dirty files involved in a rename
+ to be overwritten during merge has also been fixed as part of this
+ work. Incidentally, this also avoids updating a file in the
+ working tree after a (non-trivial) merge whose result matches what
+ our side originally had.
+
+ * "git pack-objects" needs to allocate tons of "struct object_entry"
+ while doing its work, and shrinking its size helps the performance
+ quite a bit.
