  * parser: preserve list ordering in certain scenarios (#313)
 
+ * parser: update the attoparsec version used internally giving slight
+   parsing performance boost.
+
+ * Move development to be against latest GHC release and not GHC HEAD.
+
+ * Further split up the package to separate the executable from the
+   library, necessary by things like GHCJS. We now have
+   ‘haddock-library’ which are the parts that don't use GHC API,
+   ‘haddock-api’ which are (some of) the parts that do use GHC API and
+   ‘haddock’ which merely provides the executable.
+
+ * Export few extra functions in the API.
+
+ * Add compatibility with GHC 7.8.2.
+
+ * Omit unnecessary ‘forall’s (#315 and #86)
