+Git v1.8.4.3 Release Notes
+========================
+
+Fixes since v1.8.4.2
+--------------------
+
+ * "git rev-list --objects ^v1.0^ v1.0" gave v1.0 tag itself in the
+   output, but "git rev-list --objects v1.0^..v1.0" did not.
+
+ * The fall-back parsing of commit objects with broken author or
+   committer lines were less robust than ideal in picking up the
+   timestamps.
+
+ * Bash prompting code to deal with an SVN remote as an upstream
+   were coded in a way not supported by older Bash versions (3.x).
+
+ * "git checkout topic", when there is not yet a local "topic" branch
+   but there is a unique remote-tracking branch for a remote "topic"
+   branch, pretended as if "git checkout -t -b topic remote/$r/topic"
+   (for that unique remote $r) was run. This hack however was not
+   implemented for "git checkout topic --".
+
+ * Coloring around octopus merges in "log --graph" output was screwy.
+
+ * We did not generate HTML version of documentation to "git subtree"
+   in contrib/.
+
+ * The synopsis section of "git unpack-objects" documentation has been
+   clarified a bit.
+
+ * An ancient How-To on serving Git repositories on an HTTP server
+   lacked a warning that it has been mostly superseded with more
+   modern way.
+
+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.
