+Git v1.7.1.2 Release Notes
+==========================
+
+Fixes since v1.7.1.1
+--------------------
+
+ * "git commit" did not honor GIT_REFLOG_ACTION environment variable, resulting
+   reflog messages for cherry-pick and revert actions to be recorded as "commit".
+
+ * "git clone/fetch/pull" issued an incorrect error message when a ref and
+   a symref that points to the ref were updated at the same time.  This
+   obviously would update them to the same value, and should not result in
+   an error condition.
+
+ * "git diff" inside a tree with many pathnames that have certain
+   characters has become very slow in 1.7.0 by mistake.
+
+ * "git rev-parse --parseopt --stop-at-non-option" did not stop at non option
+   when --keep-dashdash was in effect.
