+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.

+Git v1.8.4 Release Notes
+========================
+
+Updates since v1.8.3
+--------------------
+
+Foreign interface
+
+ * Remote transport helper has been updated to report errors and
+   maintain ref hierarchy used to keep track of its own state better.
+
+
+UI, Workflows & Features
+
+ * "check-ignore" (new feature since 1.8.2) has been updated to work
+   more like "check-attr" over bidi-pipes.
+
+ * We used the approxidate() parser for "--expire=<timestamp>" options
+   of various commands, but it is better to treat --expire=all and
+   --expire=now a bit more specially than using the current timestamp.
+   "git gc" and "git reflog" have been updated with a new parsing
+   function for expiry dates.
+
+
+Performance, Internal Implementation, etc.
+
+ * Object lookup logic, when the object hashtable starts to become
+   crowded, has been optimized.
+
+ * When TEST_OUTPUT_DIRECTORY setting is used, it was handled somewhat
+   inconsistently between the test framework and t/Makefile, and logic
+   to summarize the results looked at a wrong place.
+
+ * Many warnings from sparse source checker in compat/ area has been
+   squelched.
+
+ * The code to reading and updating packed-refs file has been updated,
+   correcting corner case bugs.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.3
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.3 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * When $HOME is misconfigured to point at an unreadable directory, we
+   used to complain and die. Loosen the check.
+   (merge 4698c8f jn/config-ignore-inaccessible later to maint).
+
+ * "git subtree" (in contrib/) had one codepath with loose error
+   checks to lose data at the remote side.
+   (merge 3212d56 jk/subtree-do-not-push-if-split-fails later to maint).
+
+ * "git fetch" into a shallow repository from a repository that does
+   not know about the shallow boundary commits (e.g. a different fork
+   from the repository the current shallow repository was cloned from)
+   did not work correctly.
+   (merge 71d5f93 mh/fetch-into-shallow later to maint).
+
+ * "git checkout foo" DWIMs the intended "upstream" and turns it into
+   "git checkout -t -b foo remotes/origin/foo". This codepath has been
+   updated to correctly take existing remote definitions into account.
+   (merge 229177a jh/checkout-auto-tracking later to maint).
