0.5.v  - dd/mm/yyy - bugfix release
	* 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):
	  (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
