2004-04-17 kleing 2004-04-17 added HOL-Matrix, added HOL/Matrix/ROOT.ML
2004-04-16 wenzelm 2004-04-16 Pure: 'instance' now handles general arities;
2004-04-16 berghofe 2004-04-16 Added entry for quickcheck command.
2004-04-15 wenzelm 2004-04-15 tuned;
2004-04-14 schirmer 2004-04-14 * raw control symbols are of the form \<^raw:...> now. * again allowing symbols to begin with "\\" instead of "\" for compatibility with ML-strings of old style theory and ML-files and isa-ProofGeneral.
2004-04-13 wenzelm 2004-04-13 * Calculation commands "moreover" and "also" no longer interfere with current facts ("this"), admitting arbitrary combinations with "then" and derived forms.
2004-04-13 ballarin 2004-04-13 Various changes to HOL-Algebra; Locale instantiation.

2004-01-26 schirmer 2004-01-26 * Support for raw latex output in control symbols: \<^raw...> * Symbols may only start with one backslash: \<...>. \\<...> is no longer accepted by the scanner. - Adapted some Isar-theories to fit to this policy

2003-12-10 ballarin 2003-12-10 Isar: where attribute supports instantiation of type vars.
2003-12-06 kleing 2003-12-06 moreover and also do not reset facts any more
2003-11-14 ballarin 2003-11-14 Type inference bug in Isar attributes "where" and "of" fixed.
2003-11-06 schirmer 2003-11-06 Records: - Record types are now by default printed with their type abbreviation instead of the list of all field types. This can be configured via the reference "print_record_type_abbr". - Simproc "record_upd_simproc" for simplification of multiple updates added (not enabled by default). - Tactic "record_split_simp_tac" to split and simplify records added. - Bug-fix and optimisation of "record_simproc". - "record_simproc" and "record_upd_simproc" are now sensitive to quick_and_dirty flag.
2003-11-06 ballarin 2003-11-06 Isar/Locales: <loc>.intro and <loc>.axioms no longer intro? and elim? by default.
