-0.5.1  - -/5/2008 - minor bug fix release
+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
+	* coercion hiding now works properly for coercions to funclass
+	* triangular pullback works better with coercions to the function space
+	* notation for lists fixed to add a break point after the separator
+	* notation for the existential is now user definable
+	* \infrule layout added, allows to display readable fractions
+	* better window for terms grammar and TeX/Unicode
+	* fixed a bug in the positivity check not considering some subterms
+	* fixed some GUI glitches thanks to glade-3
+
+0.5.2  - 2/7/2008 - better-usability-for-the-working-constructivist release
+	* refinement of match fixed to prevent useless unfolding,
+	  head_beta_reduce is used instead of whd ~delta:true
+	* CProp hierarchy, interleaved with type (used to be a single universe)
+	* Notation now allows to set the precedence level of subterms, avoiding
+	  unnecessary parenthese
+	* UTF-8 / TeX conversion table is now available in the Help menu
+	* Notation subsystem described in the manual
+	* EBNF term grammar is now available in the View menu (and is in sync with
+	  the currently loaded notation)
+	* Rewrite tactic (in hypothesis) now computes the right sort and
+	  uses the right equality elimination principle
+	* URI free interpretation and coercion statements (scripts are almost
+	  relocatable now)
+	* elim and cases tactic now support a pattern to specify hypotheses that 
+	  are generalized before the elimination. 
+
+0.5.1  - 29/5/2008 - minor bug fix release
 	* visualization of inductive types reports the number of fixed parameters
 	* a wrong context was used to refine fixpoints arguments
 	  when trying to optimize out the letin (grep for `AvoidLetIn):
