-0.5.1 - -/5/2008 - minor bug fix release
+0.5.7 - 15/02/2009 - Pàdoa release
+ * are_convertible bug solved, arguments of application where
+ compared allowing cumulativity. This allowed to prove Type0=Type1.
+ * cases tactic speedup in the simplest case of an inductive type
+ hose right parameters have all to be abstracted when the outtype is
+ built
+ * maction support added to output notation (adopted for "=" that
+ expands to "= \sub T" to show the equality type)
+ * generation of derived lemmas rewritten to be based on hooks that
+ are triggered every definition
+ * composition of coercions fixed, more composite are generated
+ * undo mechanism for coercions remade, should work better
+ * new command "prefer coercion foo" to reorder coercions.
+ * UTF-8 eq classes and virtuals described in the manual and
+ consistently printed in the TeX/UTF-8 table
+ * added a memory system for UTF-8 equivalence classes, so that
+ last choice is remembered and attempted first next time the same
+ eq class is walked trough
+ * some core notation fixed to allow a better setoid-path
+ representation (foo ^-1 changed precedence)
+ * matita manual updated with a section regarding the usage of
+ the liveCD with the VirtualBox emulator
+ * liveCD fixed to allow to easily mount/unmount real host folders
+ with VirtualBox
+ * ttf-freefont package added to the liveCD together with gucharmap
+ * coercions from convertible types are not inserted for real, they
+ just behave as hints for the unification algorithm
+ * virtuals (eq classes) fixed w.r.t. greek letters
+ * some virtuals added to ease the writing of diamond (<>), box ([])
+ and upper bar (_).
+ * code that generates eliminators fixed to use whd ~delta set to true
+ when counting products, this allows to used definitions as inductive
+ type ariety.
+ * match ... with rendering fixed to break the box containing
+ constructors arguments if needed (i.e. record projections
+ are now almost readable)
+ * fixed pattern matching over ast terms, Ast.Case construct can be
+ matched correctly. Look the o-algebra example if you are
+ intereseted.
+ * Mpadded MathML tag can be used in notation, it allows to overlap
+ symbols reducing the bounding box size
+
+0.5.6 - 1/12/2008 - bugfix release
+ * more abstract disambiguation algorithm, simpler instantiation
+ to a different CIC/refiner
+ * natural deduction support improved in the first order case
+ * natural deduction lem rule does now support lemmas
+ with (up to) 3 premises (multicut rule, displayed as
+ a collapsed tree)
+
+0.5.5 - 17/11/2008 - bugfix release with students in mind
+ * by ... we proved fixed to use only the specified lemmas but
+ using full unification inside auto.
+ * new apply rule tactic, that exploits the goal type to
+ disambiguate the input term.
+ * new didactic/ library directory, with support for natural deduction
+ treese.
+
+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):
(let rec f x = Fix... in f t ---> Fix... t)
- * auto fixed to prefer goals with metavariables to closed ones
+ * 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
