+GIT v1.5.0.7 Release Notes
+==========================
+
+Fixes since v1.5.0.6
+--------------------
+
+* Bugfixes
+
+  - git-upload-pack failed to close unused pipe ends, resulting
+    in many zombies to hang around.
+
+  - git-rerere was recording the contents of earlier hunks
+    duplicated in later hunks.  This prevented resolving the same
+    conflict when performing the same merge the other way around.
+
+* Documentation
+
+  - a few documentation fixes from Debian package maintainer.
