+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
