+v3.0.1 2017-06-09
+-----------------
 
 - ppx: remove an errant standalone initialiser that was messing up
   the composition of cstruct with other `ppx_driver` based ppx converters
   (most notably `ppx_sexp_conv`.  If you are having trouble with using
   `ppx_cstruct` with other drivers, put a constraint on `ppx_cstruct>=3.0.1`.
+  (#151 #150 #149 #148 via @djs55 @g2p @avsm @diml).
 - ppx: also add a test case for `cstruct` and `lwt` working together, but
   this will not work until a `lwt>3.0` release happens.
 - Update opam rules to use `jbuilder subst` for version information
