+- Update to version 3.7:
+  * bugfix - diff --strip-trailing-cr with a single CR byte in one
+    input file would provoke an uninitialized memory read
+  * diff --color now produces output compatible with less -R.
+- Small packaging cleanups:
+  * PIE is now default for whole distribution
+  * xz is not needed as build dependency anymore
