+[v1.5.1][] - 2016-04-17
+-----------------------
+
+Minor fix release.
+
+### Changes
+- Update README.md, add help when libite is used in autotools projects.
+  Spell checking and minor cleanup.
+
+### Fixes
+- Activate use of `utimensat()` when `pidfile()` is called multiple
+  times.  This reduces the overhead of calling open+write+close to
+  simply updating the mtime of the PID file.
+- Westermo fixes for `fcopyfile()`: nothing copied on embedded PPC
+  system when using `tmpfile()` as source.
