-       * code that generates eliminators fixed to use whd ~delta:true
-         when counting products, this allows to used definitions as inductive type
-               ariety.
+0.5.7 - .../01/2009 - 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
+       * undo mechanism for coercions remade, should work better
+       * new command "prefer coercion foo" to reorder coercions.
+       * UTF-8 eq classes and virtuals described in the manual and
+         consistently printed in the TeX/UTF-8 table
+       * added a memory system for UTF-8 equivalence classes, so that
+         last choice is remembered and attempted first next time the same
+         eq class is walked trough
+       * some core notation fixed to allow a better setoid-path
+         representation (foo ^-1 changed precedence)
+       * 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
+         with VirtualBox
+       * 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
+       * Mpadded MathML tag can be used in notation, it allows to overlap
          symbols reducing the bounding box size
