+   An explicit way to help the end users who connect to the service by
+   issuing custom messages to refuse such an access has been added.

+ * "git status" suggests users to look into using--untracked=no option
+   when it takes too long.

+ * "git fetch" learned to fetch a commit at the tip of an unadvertised
+   ref by specifying a raw object name from the command line when the
+   server side supports this feature.
+
+ * "git count-objects -v" learned to report leftover temporary
+   packfiles and other garbage in the object store.
+
+ * A new read-only credential helper (in contrib/) to interact with
+   the .netrc/.authinfo files has been added.
+
+ * "git send-email" can be used with the credential helper system.
