+ * A fourth class of configuration files (in addition to the

* Windows port learned to use nano-second resolution file timestamps.

+ * Unify code to read the author-script used in "git am" and the

+ * In preparation to the day when we can deprecate and remove the
+ "rebase -p", make sure we can skip and later remove tests for
+ it.
+ * The history traversal used to implement the tag-following has been
+ optimized by introducing a new helper.
+ * The helper function to refresh the cached stat information in the
+ in-core index has learned to perform the lstat() part of the
+ operation in parallel on multi-core platforms.
+ * The code to traverse objects for reachability, used to decide what
+ objects are unreferenced and expendable, have been taught to also
+ consider per-worktree refs of other worktrees as starting points to
+ prevent data loss.
+ * "git add" needs to internally run "diff-files" equivalent, and the
+ codepath learned the same optimization as "diff-files" has to run
+ lstat(2) in parallel to find which paths have been updated in the
+ working tree.
+ * The procedure to install dependencies before testing at Travis CI
+ is getting revamped for both simplicity and flexibility, taking
+ advantage of the recent move to the vm-based environment.
+ * The support for format-patch (and send-email) by the command-line
+ completion script (in contrib/) has been simplified a bit.
