+0.5.7 - ... - ...
+	* code that generates eliminators fixed to use whd ~delta:true
+	  when counting products, this allows to used definitions as inductive type
+		ariety.
+	* match ... with rendering fixed to break the box containing
+	  constructors arguments if needed (i.e. record projections
+	  are now almost readable)
+	* fixed pattern matching over ast terms, Ast.Case construct can be
+	  matched correctly. Look the o-algebra example if you are
+	  intereseted.
+	* mpadded mathml tag can be used in notation, it allows to overlap
+	  symbols reducing the bounding box size 
+
+0.5.6 - 1/12/2008 - bugfix release
+	* more abstract disambiguation algorithm, simpler instantiation
+	  to a different CIC/refiner
+	* natural deduction support improved in the first order case
+	* natural deduction lem rule does now support lemmas 
+	  with (up to) 3 premises (multicut rule, displayed as
+	  a collapsed tree)
+
+0.5.5  - 17/11/2008 - bugfix release with students in mind	
+	* by ... we proved fixed to use only the specified lemmas but
+	  using full unification inside auto.
+	* new apply rule tactic, that exploits the goal type to
+	  disambiguate the input term.
+	* new didactic/ library directory, with support for natural deduction
+	  treese.

 0.5.4  - 19/10/2008 - bugfix release	
 	* When a file is opened, the cursor is placed at the begin of the
 	  buffer and not atthe end as before
