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;
2010-08-26 wenzelm 2010-08-26 renamed ProofContext.theory(_result) to ProofContext.background_theory(_result) to emphasize that this belongs to the infrastructure and is rarely appropriate in user-space tools;
2010-08-19 haftmann 2010-08-19 tuned quotes
2010-08-19 haftmann 2010-08-19 use antiquotations for remaining unqualified constants in HOL
2010-05-17 wenzelm 2010-05-17 prefer structure Keyword, Parse, Parse_Spec, Outer_Syntax; eliminated old-style structure aliases K = Keyword, P = Parse;
2010-05-16 wenzelm 2010-05-16 prefer structure Parse_Spec;
2010-05-15 wenzelm 2010-05-15 less pervasive names from structure Thm;
2010-05-04 wenzelm 2010-05-04 specification goal: eliminated redundant Thm.legacy_freezeT -- the goal is properly declared and should always produce fixed types in the result; specification result: replaced Thm.legacy_freezeT by Thm.unvarify_global -- the final result appears to be a closed term that is globally exported;
2010-05-03 wenzelm 2010-05-03 renamed Thm.freezeT to Thm.legacy_freezeT -- it is based on Type.legacy_freeze;
2010-05-03 wenzelm 2010-05-03 renamed ProofContext.init to ProofContext.init_global to emphasize that this is not the real thing;

2010-03-22 wenzelm 2010-03-22 eliminated old-style Drule.add_axiom in favour of Specification.axiom, with explicit Drule.export_without_context to imitate the old behaviour;
2010-03-22 wenzelm 2010-03-22 replaced PureThy.add_axioms by more basic Drule.add_axiom, which is old-style nonetheless;
2010-03-20 wenzelm 2010-03-20 renamed varify/unvarify operations to varify_global/unvarify_global to emphasize that these only work in a global situation;
2010-03-17 blanchet 2010-03-17 added support for "specification" and "ax_specification" constructs to Nitpick
2010-03-07 wenzelm 2010-03-07 modernized structure Object_Logic;
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;
