2 * match ... with rendering fixed to break the box containing
3 constructors arguments if needed (i.e. record projections
4 are now almost readable)
5 * fixed pattern matching over ast terms, Ast.Case construct can be
6 matched correctly. Look the o-algebra example if you are
8 * mpadded mathml tag can be used in notation, it allows to overlap
9 symbols reducing the bounding box size
11 0.5.6 - 1/12/2008 - bugfix release
12 * more abstract disambiguation algorithm, simpler instantiation
13 to a different CIC/refiner
14 * natural deduction support improved in the first order case
15 * natural deduction lem rule does now support lemmas
16 with (up to) 3 premises (multicut rule, displayed as
19 0.5.5 - 17/11/2008 - bugfix release with students in mind
20 * by ... we proved fixed to use only the specified lemmas but
21 using full unification inside auto.
22 * new apply rule tactic, that exploits the goal type to
23 disambiguate the input term.
24 * new didactic/ library directory, with support for natural deduction
27 0.5.4 - 19/10/2008 - bugfix release
28 * When a file is opened, the cursor is placed at the begin of the
29 buffer and not atthe end as before
31 * More code in the direction of a fully functional matita status, that
32 improved undo reliability in the parser/notation modules
33 * matitac was seldom compiling up-to-date files, fixed
34 * Memory consumption durin proof construction cut down using Lazy.t
36 * mstyle support in notation for text color, font size
37 * AutoGui now scales fonts to the correct user-requested size
38 * Non linear pattern matching from the level of terms to the
39 one of content in interpretation command (if the same variable name
40 is used, the two captured terms must be alpha equivalent to match)
42 0.5.3 - 23/7/2008 - bugfix release
43 * many fixes concerning the CProp hiearchy
44 * coercion database simplified
45 * coercion hiding now works properly for coercions to funclass
46 * triangular pullback works better with coercions to the function space
47 * notation for lists fixed to add a break point after the separator
48 * notation for the existential is now user definable
49 * \infrule layout added, allows to display readable fractions
50 * better window for terms grammar and TeX/Unicode
51 * fixed a bug in the positivity check not considering some subterms
52 * fixed some GUI glitches thanks to glade-3
54 0.5.2 - 2/7/2008 - better-usability-for-the-working-constructivist release
55 * refinement of match fixed to prevent useless unfolding,
56 head_beta_reduce is used instead of whd ~delta:true
57 * CProp hierarchy, interleaved with type (used to be a single universe)
58 * Notation now allows to set the precedence level of subterms, avoiding
59 unnecessary parenthese
60 * UTF-8 / TeX conversion table is now available in the Help menu
61 * Notation subsystem described in the manual
62 * EBNF term grammar is now available in the View menu (and is in sync with
63 the currently loaded notation)
64 * Rewrite tactic (in hypothesis) now computes the right sort and
65 uses the right equality elimination principle
66 * URI free interpretation and coercion statements (scripts are almost
68 * elim and cases tactic now support a pattern to specify hypotheses that
69 are generalized before the elimination.
71 0.5.1 - 29/5/2008 - minor bug fix release
72 * visualization of inductive types reports the number of fixed parameters
73 * a wrong context was used to refine fixpoints arguments
74 when trying to optimize out the letin (grep for `AvoidLetIn):
75 (let rec f x = Fix... in f t ---> Fix... t)
76 * auto fixed to prefer goals with metavariables to closed ones,
77 added new syntax to specify the universe "auto by t1, t2, ...",
78 updated documentation describing all auto parameters
79 * declarative language syntax and documentation ported to the new
82 0.5.0 - 9/5/2008 - bugfix release
83 * first release not considered experimental
85 0.4.98 - ??/11/2007 - bugfix release
86 * compiles against camlp5 >= 5.0
87 * changed lablgtksourceview module name since it is now part of lablgtk2
89 0.4.97 - 16/11/2007 - initial release
