2010-12-04 ago formal notepad without any result;
2010-11-28 ago added 'syntax_declaration' command;
2010-11-07 ago 'example_proof' is treated as non-schematic statement with irrelevant proof (NB: even regular proofs can contain unreachable parts wrt. the graph of proof promises);
2010-11-06 ago mark 'cd' and 'commit' as control command -- not usable in asynchronous document model, likely to cause confusion in Proof General;
2010-09-08 ago removed ancient constdefs command
2010-09-06 ago discontinued obsolete ProofContext.prems_limit;
2010-08-31 ago moved Toplevel.run_command to Pure/PIDE/document.ML;

2010-07-31 ago Interpretation in proofs supports mixins.
2010-07-28 ago explicit Keyword.control markup for various control commands -- to prevent them from occurring in proof documents;
2010-07-27 ago theory loader: removed obsolete touch/outdate operations (require_thy no longer changes the database implicitly);
2010-07-27 ago simplified/clarified theory loader: more explicit task management, kill old versions at start, commit results only in the very end, non-optional master dependency, do not store text in deps;
2010-07-24 ago moved management of auxiliary theory source files to Thy_Load -- as theory data instead of accidental loader state;
2010-07-21 ago eliminated old time_use/time_use_thy variants -- timing is implicitly controlled via Output.timing;
2010-07-20 ago warning in proper transaction context;
2010-05-31 ago modernized some structure names, keeping a few legacy aliases;
2010-05-30 ago replaced ML_Lex.read_antiq by more concise, which includes full read/report with explicit position information;
2010-05-15 ago renamed structure OuterSyntax to Outer_Syntax, keeping the old name as alias for some time;
2010-05-15 ago renamed structure SpecParse to Parse_Spec, keeping the old name as alias for some time;

2010-04-26 ago command 'example_proof' opens an empty proof body;
2010-04-25 ago modernized naming conventions of main Isar proof elements;
2010-04-23 ago explicit 'schematic_theorem' etc. for schematic theorem statements;
2010-04-16 ago keep localized 'types' as regular non-old-style version -- 'type_abbrev' as 'type' just causes too many problems, e.g. clash with "type" in translations or "type:" argument syntax;
2010-04-16 ago replaced generic 'hide' command by more conventional 'hide_class', 'hide_type', 'hide_const', 'hide_fact' -- frees some popular keywords;
2010-04-16 ago modernized old-style type abbreviations;
2010-04-16 ago local type abbreviations;
2010-04-11 ago user interface for abstract datatypes is an attribute, not a command

2009-11-08 ago print_theorems: suppress concealed (global) facts, unless "!" option is given;
2009-11-05 ago allow "pervasive" local theory declarations, which are applied the background theory;
2009-11-02 ago modernized structure Proof_Node;
2009-10-28 ago provide SpecParse.constdecl/constdef, e.g. for quotient_definition;
