-0.5.v  - dd/mm/yyy - bugfix release
+0.5.7 - ... - ...
+       * 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
        * New macro eval
        * More code in the direction of a fully functional matita status, that
          improved undo reliability in the parser/notation modules
