+  o [logic] accept type expressions in clone substitutions
+  o [whyml] support for relation chains (e.g., "e1 = e2 < e3")
+  * [whyml] every exception raised in a function must be listed
+    in as "raises { ... }" clause. A postcondition may be omitted
+    and equals to "true" by default.
+  * [whyml] if a function definition contains a "writes { ... }"
+    clause, then every write effect must be listed. If a function
+    definition contains a "reads { ... }" clause, then every read
+    _and_ write effect must be listed.
+  * [drivers] syntax rules, metas, and preludes are inherited
+    through cloning. Keyword "cloned" becomes unnecessary and
+    is not accepted anymore.
   o [why3ide] allow several files on the command-line
   o [ocaml API] incompatible changes in Set/Map/Hashtbl modules
   o [ocaml API] examples in the manual extended to API for Why3ml programs
