+0.5.7 - .../12/2008 - Pàdoa release
+       * some core notation fixed to allow a better setoid-path
+         representation
+       * matita manual updated with a section regarding the usage of 
+         the liveCD with the VirtualBox emulator
+       * liveCD fixed to allow to easily mount/unmount real host folders
+       * ttf-freefont package added to the liveCD together with gucharmap
+       * coercions from convertible types are not inserted for real, they
+         just behave as hints for the unification algorithm
+       * virtuals (eq classes) fixed w.r.t. greek letters
+       * some virtuals added to ease the writing of diamond (<>), box ([])
+         and upper bar (_).
+       * code that generates eliminators fixed to use whd ~delta set to 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
