-0.5.v  - dd/mm/yyy - bugfix release
+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
+	* 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
