-0.5.7 - .../01/2009 - Pàdoa release
+0.5.8 - 02/12/2009 - toward the 1.x series
+	* Complete rewriting of paramodulation code (thanks to Maxime Denes),
+	  that is abstract over the data type embedded in the fisrt order
+	  theory the procedure is able to handle. 
+	  Can be used as a stand-alone prover, and partecipated
+	  to the CASC22 beating many older systems ;-)
+	* new (compact) kernel:
+	  * toplevel fixpoints 
+	  * height (inter object dependency) driven conversion
+	  * compact metavariable representation
+	  * experimental irrelevant arguments handling in convesion
+	    (in the spirit of proof irrelevance)
+	  * explicit predicative universes
+	* new refiner:
+	  * bi-directional type inference
+	  * unification hints
+	  * implicit vector (expands to the right number of implicits)
+	* new basic tactics:
+	  * new type for tactics, with a global view on the ongoing proof
+	  * heavily based on the refiner
+	  * work with terms labelled with their contexts
+	* new auto (prolog like) proof search tactic:
+	  * works on a set of goals
+	  * non uniform context support:
+	    * arbitrary tactics can be called to attack a goal (hardcoded 
+	      at the OCaml level), for now just apply and intro
+	* new installation:
+	  * the standard library (now we have two of them) is not
+	    distributed pre-compiled
+	  * standard library .ma files can be included from everywhere since
+	    they are in a standard path
+	  * including a file of the standard library triggers its compilation
+	    in the user's space
+	* gtksourceview2 based text widget (lablgtk >= 2.14)
+
+0.5.7 - 15/02/2009 - Pàdoa release
+	* are_convertible bug solved, arguments of application where 
+	  compared allowing cumulativity. This allowed to prove Type0=Type1.
+	* cases tactic speedup in the simplest case of an inductive type 
+	  hose right parameters have all to be abstracted when the outtype is
+	  built
+	* maction support added to output notation (adopted for "=" that 
+	  expands to "= \sub T" to show the equality type)
 	* generation of derived lemmas rewritten to be based on hooks that
 	  are triggered every definition
 	* composition of coercions fixed, more composite are generated
