2010-12-16 boehmes 2010-12-16 turned simp_trace_depth_limit into a configuration option
2010-12-02 wenzelm 2010-12-02 configuration option "show_abbrevs" supersedes print mode "no_abbrevs", with inverted meaning;
2010-12-02 wenzelm 2010-12-02 renamed trace_simp to simp_trace, and debug_simp to simp_debug;
2010-10-30 wenzelm 2010-10-30 support for real valued configuration options;
2010-09-20 wenzelm 2010-09-20 renamed structure PureThy to Pure_Thy and moved most content to Global_Theory, to emphasize that this is global-only;

2010-09-06 wenzelm 2010-09-06 turned show_hyps and show_tags into proper configuration option;
2010-09-06 wenzelm 2010-09-06 more explicit indication of Config.raw options, which are only needed for bootstrapping Pure;
2010-09-05 wenzelm 2010-09-05 turned show_brackets into proper configuration option; Sign.certify/type_check: dropped Syntax.pp_show_brackets, which is hard to hold up due to Pretty.pp and not even present in the regular end-user type check;
2010-09-05 wenzelm 2010-09-05 turned show_sorts/show_types into proper configuration options;
2010-09-03 wenzelm 2010-09-03 turned eta_contract into proper configuration option;
2010-09-03 wenzelm 2010-09-03 turned show_structs into proper configuration option;
2010-09-03 wenzelm 2010-09-03 configuration options Syntax.ambiguity_enabled (inverse of former Syntax.ambiguity_is_error), Syntax.ambiguity_level (with Isar attribute "syntax_ambiguity_level"), Syntax.ambiguity_limit;
2010-09-03 wenzelm 2010-09-03 pretty_goals: turned some global references and function arguments into configuration options (goals_limit = 10, goals_total = true, show_main_goal = false) depending on the context;
2010-09-03 wenzelm 2010-09-03 treat show_free_types as plain ML option, without the extras of global default and registration in the attribute name space -- NB: 'print_configs' only shows the latter;
2010-09-03 wenzelm 2010-09-03 more explicit Config.declare vs. Config.declare_global;
2010-09-03 wenzelm 2010-09-03 turned show_no_free_types into proper configuration option show_free_types, with flipped polarity;

2010-09-02 wenzelm 2010-09-02 turned show_question_marks into proper configuration option; show_question_marks only affects regular type/term pretty printing, not raw Term.string_of_vname; tuned;
2010-08-11 wenzelm 2010-08-11 tuned eval_thms (cf. note etc. in proof.ML);
2010-08-11 wenzelm 2010-08-11 use Pretty.enum convenience;
2010-05-30 wenzelm 2010-05-30 replaced ML_Lex.read_antiq by more concise, which includes full read/report with explicit position information; ML_Context.eval/expression expect explicit ML_Lex source, which allows surrounding further text without loosing position information; fall back on ML_Context.eval_text if there is no position or no surrounding text; proper Args.name_source_position for method "tactic" and "raw_tactic"; tuned;
2010-05-17 wenzelm 2010-05-17 renamed structure OuterLex to Token and type token to Token.T, keeping legacy aliases for some time; eliminated slightly odd alias structure T;
2010-05-15 wenzelm 2010-05-15 refer directly to structure Keyword and Parse; eliminated old-style structure aliases K and P;
2010-05-10 wenzelm 2010-05-10 renamed Config.get_thy to Config.get_global etc. to indicate that this is not the real thing;
2010-03-28 wenzelm 2010-03-28 pass raw Context.generic, to avoid wasteful Context.proof_of -- Config.get_thy is often used in performance critical spots like unify.ML;
2010-03-28 wenzelm 2010-03-28 configuration options admit dynamic default values;
2010-03-28 wenzelm 2010-03-28 do not export Attrib.register_config, to make it harder to use low-level Config.declare after the bootstrap phase;
2010-03-26 boehmes 2010-03-26 replaced references 'trace_simp' and 'debug_simp' by configuration options stored in the context

2010-03-07 wenzelm 2010-03-07 modernized structure Local_Defs;
2010-02-07 wenzelm 2010-02-07 renamed old-style Drule.standard to Drule.export_without_context, to emphasize that this is in no way a standard operation;
2010-01-30 berghofe 2010-01-30 Added "constraints" tag / attribute for specifying the number of equality constraints in cases rules.
2009-11-13 wenzelm 2009-11-13 eliminated obsolete "generated" kind -- collapsed to unspecific "" (definitely unused according to Lukas Bulwahn);
2009-11-08 wenzelm 2009-11-08 adapted Theory_Data; tuned;
2009-11-01 wenzelm 2009-11-01 modernized structure Rule_Cases;

2009-10-24 wenzelm 2009-10-24 maintain explicit name space kind; export Name_Space.the_entry; tuned messages;
2009-10-24 wenzelm 2009-10-24 renamed NameSpace to Name_Space -- also to emphasize its subtle change in semantics;
2009-10-24 wenzelm 2009-10-24 eliminated separate stamp -- NameSpace.define/merge etc. ensure uniqueness already;
2009-06-24 wenzelm 2009-06-24 renamed Variable.import_thms to Variable.import (back again cf. ed7aa5a350ef -- Alice is no longer supported); renamed Variable.importT_thms to Variable.importT (again);
2009-06-02 wenzelm 2009-06-02 merged, resolving conflict in src/Pure/Isar/attrib.ML;
2009-06-02 haftmann 2009-06-02 made SML/NJ happy
2009-06-01 wenzelm 2009-06-01 made SML/NJ happy;

2009-05-18 haftmann 2009-05-18 introduced Thm.generatedK
2009-05-16 bulwahn 2009-05-16 added new kind generated_theorem for theorems which are generated by packages to distinguish between theorems from users and packages
2009-03-28 wenzelm 2009-03-28 renamed ProofContext.note_thmss_i to ProofContext.note_thmss, eliminated obsolete external version;
2009-03-28 wenzelm 2009-03-28 added map_facts_refs;
2009-03-18 wenzelm 2009-03-18 more precise type Symbol_Pos.text;
2009-03-16 wenzelm 2009-03-16 tuned signature;
2009-03-15 wenzelm 2009-03-15 added setup and attribute_setup -- expect plain parser instead of syntax function; aded add_del parser;
2009-03-13 wenzelm 2009-03-13 eliminated type Args.T; pervasive types 'a parser and 'a context_parser;
2009-03-12 wenzelm 2009-03-12 renamed NameSpace.bind to NameSpace.define;
2009-03-04 blanchet 2009-03-04 Merge.
2009-03-04 blanchet 2009-03-04 Merge.
