+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
 
-       * NEWS: Version 0.1.0 (alpha)
-       * First public release of Matita.
+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):
+         (let rec f x = Fix... in f t ---> Fix... t)
+       * auto fixed to prefer goals with metavariables to closed ones,
+         added new syntax to specify the universe "auto by t1, t2, ...",
+               updated documentation describing all auto parameters
+       * declarative language syntax and documentation ported to the new 
+         auto parameters
+
+0.5.0  - 9/5/2008 - bugfix release
+       * first release not considered experimental
+
+0.4.98 - ??/11/2007 - bugfix release
+       * compiles against camlp5 >= 5.0  
+       * changed lablgtksourceview module name since it is now part of lablgtk2
+
+0.4.97 - 16/11/2007 - initial release
