+
+## Enhancements
+
+* The main `gisele` command now accepts a --no-sugar option that removes syntactic
+  sugar. This option is limited to the rewriting of `if` statements as guarded `case`
+  commands for now. Additional rewriting could be added in the future.
+* All AST nodes (obtained via `Gisele.ast` or similar) now include the module 
+  `Gisele::Language::AST::Node` which contains a few utilities.
+
+## Breaking changes
+
+* The language package has been reorganized and is now considered as belonging to
+  the private API. Further changes there will therefore not b considered as Breaking
+  changes in the future (expect the structure of the AST, of course). 
+  The `Gisele.parse` and `Gisele.ast` methods belong to the public API and are therefore
+  the way to (parse / get an AST) from a process file / source.
+
+* The top AST element of a process file is always a :unit. The latter may contain 
+  one ore more task definitions. Import/include nodes will probably be added later
+  and authorized at the beginning of the file.
+
+* The following syntax nodes have been renamed:
+    :varref     -> :var_ref
+    :or         -> :bool_or
+    :and        -> :bool_and
+    :not        -> :bool_not
+    :if         -> :if_st
+    :else       -> :else_clause
+    :elsif      -> :elsif_clause
+    :while      -> :while_st
+    :seq        -> :seq_st
+    :par        -> :par_st
+    :task_call  -> :task_call_st
+    :task       -> :task_def
+    :signature  -> :task_signature
+    :refinement -> :task_refinement
