-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
+       * matitac was seldom compiling up-to-date files, fixed
+       * Memory consumption durin proof construction cut down using Lazy.t
+         proof terms
        * mstyle support in notation for text color, font size

+       * AutoGui now scales fonts to the correct user-requested size 
+       * Non linear pattern matching from the level of terms to the
          one of content in interpretation command (if the same variable name
          is used, the two captured terms must be alpha equivalent to match)

 0.5.3  - 23/7/2008 - bugfix release
        * many fixes concerning the CProp hiearchy
        * coercion database simplified
