+Git v1.6.4.5 Release Notes
+==========================
+
+Fixes since v1.6.4.4
+--------------------
+
+ * Simplified base85 implementation.
+
+ * An overlong line after ".gitdir: " in a git file caused out of bounds
+   access to an array on the stack.
+
+ * "git count-objects" did not handle packs larger than 4G.
+
+ * "git rev-parse --parseopt --stop-at-non-option" did not stop at non option
+   when --keep-dashdash was in effect.
+
+ * "gitweb" can sometimes be tricked into parrotting a filename argument
+   given in a request without properly quoting.
+
+Other minor fixes and documentation updates are included.
