+0.5.3  - ?/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
+
+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
