+GIT v1.5.3.6 Release Notes
+==========================
+
+Fixes since v1.5.3.5
+--------------------
+
+ * git-cvsexportcommit handles root commits better;
+
+ * git-svn dcommit used to clobber when sending a series of
+   patches;
+
+ * git-grep sometimes refused to work when your index was
+   unmerged;
+
+ * Quite a lot of documentation clarifications.
