* A credential helper to allow access to the Gnome keyring has been
added.
+ * When "git am" sanitizes the Subject: line, we strip the prefix from
+ "Re: subject" and also from a less common "re: subject", but left
+ even less common "RE: subject" intact.
+
* It was tempting to say "git branch --set-upstream origin/master",
but that tells Git to arrange the local branch "origin/master" to
integrate with the currently checked out branch, which is highly
* "git merge-base" learned "--is-ancestor A B" option to tell if A is
an ancestor of B. The result is indicated by its exit status code.
+ * The "-Xours" backend option to "git merge -s recursive" now takes
+ effect even on binary files.
+
Foreign Interface
* Compatibility wrapper for systems that lack usable setitimer() has
been added.
+ * The option parsing of "git checkout" had error checking, dwim and
+ defaulting missing options, all mixed in the code, and issuing an
+ appropriate error message with useful context was getting harder.
+ The code has been reorganized to allow giving a proper diagnosis
+ when the user says "git checkout -b -t foo bar" (e.g. "-t" is not a
+ good name for a branch).
+
* Many internal uses of "git merge-base" equivalent were only to see
if one commit fast-forwards to the other, which did not need the
full set of merge bases to be computed. They have been updated to
maintenance track are contained in this release (see release notes
to them for details).
+ * "git fetch --all", when passed "--no-tags", did not honor the
+ "--no-tags" option while fetching from individual remotes (the same
+ issue existed with "--tags", but combination "--all --tags" makes
+ much less sense than "--all --no-tags").
+ (merge 8556646 dj/fetch-all-tags later to maint).
+
* The subcommand in "git remote" to remove a defined remote was
"rm" and the command did not take a fully-spelled "remove".
