+Development version
+===================
+
+- More efficient implementation of machine integers (module Integers)
+  taking advantage of bitwise operations defined in ZArith in Coq 8.4.
+- Fixed a bug in the reference interpreter in -all mode causing some
+  reductions to be incorrectly merged.
+- Better error and warning messages for declarations of variables
+  of size >= 2^32 bits.
