+Git v2.4.11 Release Notes
+=========================
+
+Fixes since v2.4.10
+-------------------
+
+ * Bugfix patches were backported from the 'master' front to plug heap
+   corruption holes, to catch integer overflow in the computation of
+   pathname lengths, and to get rid of the name_path API.  Both of
+   these would have resulted in writing over an under-allocated buffer
+   when formulating pathnames while tree traversal.
