2015-09-23 wenzelm 2015-09-23 tuned signature;

2011-11-08 wenzelm 2011-11-08 more specific treatment of defines/assumes -- avoid normalizing defs by themselves (NB: locale specifications and Local_Theory.define may lead to arbitrary mixture);
2011-10-28 wenzelm 2011-10-28 uniform Local_Theory.declaration with explicit params;
2011-04-17 wenzelm 2011-04-17 added Binding.print convenience, which includes quote already;
2011-04-17 wenzelm 2011-04-17 report Name_Space.declare/define, relatively to context; added "global" variants of context-dependent declarations;
2011-04-16 wenzelm 2011-04-16 modernized structure Proof_Context;
2011-04-08 wenzelm 2011-04-08 discontinued special treatment of structure Lexicon;
2010-08-26 wenzelm 2010-08-26 renamed Local_Theory.theory(_result) to Local_Theory.background_theory(_result) to emphasize that this belongs to the infrastructure and is rarely appropriate in user-space tools;
2010-08-12 haftmann 2010-08-12 Named_Target.theory_init
2010-08-11 haftmann 2010-08-11 renamed Theory_Target to the more appropriate Named_Target
2010-05-17 wenzelm 2010-05-17 prefer structure Keyword, Parse, Parse_Spec, Outer_Syntax; eliminated old-style structure aliases K = Keyword, P = Parse;

2010-04-25 wenzelm 2010-04-25 modernized naming conventions of main Isar proof elements;
2010-04-15 wenzelm 2010-04-15 replaced slightly odd Typedecl.predeclare_constraints by plain declaration of type arguments -- also avoid "recursive" declaration of type constructor, which can cause problems with sequential definitions =; simplified via ProofContext.check_tfree;
2010-04-11 wenzelm 2010-04-11 expose foundational typedef axiom name;
2010-04-11 wenzelm 2010-04-11 Thm.add_axiom/add_def: return internal name of foundational axiom;
2010-03-27 wenzelm 2010-03-27 separate global and local part, only the latter is transformed by morphisms;

2010-03-13 wenzelm 2010-03-13 Local_Theory.define handles hidden polymorphism;
2010-03-13 wenzelm 2010-03-13 localized typedef; Typedef.get_info can yield multiple typedef interpretations, even in a global context; misc tuning and modernization;
2010-03-09 wenzelm 2010-03-09 Typedecl.typedecl_global;
2010-03-07 wenzelm 2010-03-07 separate structure Typedecl;
2010-03-07 wenzelm 2010-03-07 modernized structure Object_Logic;
2010-03-03 wenzelm 2010-03-03 adapted to authentic syntax -- actual types are verbatim;

2010-02-19 wenzelm 2010-02-19 Thm.def_binding;

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;
