  * The "git pack-objects --path-walk" traversal has been integrated

+ * The 'git-jump' command (in contrib/) has been taught to automatically
+   pick a mode (merge, diff, or ws) when invoked without arguments.

+ * The documentation for `push.default = simple` has been clarified to
+   better explain its behavior, making it clear that it pushes the
+   current branch to a same-named branch on the remote, and detailing
