-0.5.7 - .../12/2008 - Pàdoa release
+0.5.8 - 02/12/2009 - toward the 1.x series
+ * Complete rewriting of paramodulation code (thanks to Maxime Denes),
+ that is abstract over the data type embedded in the fisrt order
+ theory the procedure is able to handle.
+ Can be used as a stand-alone prover, and partecipated
+ to the CASC22 beating many older systems ;-)
+ * new (compact) kernel:
+ * toplevel fixpoints
+ * height (inter object dependency) driven conversion
+ * compact metavariable representation
+ * experimental irrelevant arguments handling in convesion
+ (in the spirit of proof irrelevance)
+ * explicit predicative universes
+ * new refiner:
+ * bi-directional type inference
+ * unification hints
+ * implicit vector (expands to the right number of implicits)
+ * new basic tactics:
+ * new type for tactics, with a global view on the ongoing proof
+ * heavily based on the refiner
+ * work with terms labelled with their contexts
+ * new auto (prolog like) proof search tactic:
+ * works on a set of goals
+ * non uniform context support:
+ * arbitrary tactics can be called to attack a goal (hardcoded
+ at the OCaml level), for now just apply and intro
+ * new installation:
+ * the standard library (now we have two of them) is not
+ distributed pre-compiled
+ * standard library .ma files can be included from everywhere since
+ they are in a standard path
+ * including a file of the standard library triggers its compilation
+ in the user's space
+ * gtksourceview2 based text widget (lablgtk >= 2.14)
+
+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
+ 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
