  * "git p4" used a location outside $GIT_DIR/refs/ to place its
    temporary branches, which has been moved to refs/git-p4-tmp/.
 
+ * Existing autoconf generated test for the need to link with pthread
+   library did not check all the functions from pthread libraries;
+   recent FreeBSD has some functions in libc but not others, and we
+   mistakenly thought linking with libc is enough when it is not.
+   (merge a9b02de ew/autoconf-pthread later to maint).
+
+ * When "git fsck" reports a broken link (e.g. a tree object contains
+   a blob that does not exist), both containing object and the object
+   that is referred to were reported with their 40-hex object names.
+   The command learned the "--name-objects" option to show the path to
+   the containing object from existing refs (e.g. "HEAD~24^2:file.txt").
+
+ * Allow http daemon tests in Travis CI tests.
+   (merge d9d1426 ls/travis-enable-httpd-tests later to maint).
+
+ * Makefile assumed that -lrt is always available on platforms that
+   want to use clock_gettime() and CLOCK_MONOTONIC, which is not a
+   case for recent Mac OS X.  The necessary symbols are often found in
+   libc on many modern systems and having -lrt on the command line, as
+   long as the library exists, had no effect, but when the platform
+   removes librt.a that is a different matter--having -lrt will break
+   the linkage.
+
+   This change could be seen as a regression for those who do need to
+   specify -lrt, as they now specifically ask for NEEDS_LIBRT when
+   building. Hopefully they are in the minority these days.
+
+ * Further preparatory work on the refs API before the pluggable
+   backend series can land.
+
+ * Error handling in the codepaths that updates refs has been
+   improved.
+
+ * The API to iterate over all the refs (i.e. for_each_ref(), etc.)
+   has been revamped.
