-0.5.1  - -/5/2008 - minor bug fix release
+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):
