2013-07-15 ago retain compile-time context visibility, which is particularly important for "apply tactic";

2011-04-16 ago modernized structure Proof_Context;
2011-01-09 ago ML_trace: observe context visibility flag (import for Latex mode, for example);
2010-12-21 ago configuration option "ML_trace";
2010-10-01 ago moved ML_Context.value to Code_Runtime
2010-09-30 ago value uses bare compiler invocation: generated code does not contain antiquotations

2010-09-06 ago ML_Context.thm and ML_Context.thms no longer pervasive;
2010-09-06 ago ML_Context.ml_store_thm(s): operate on thread context instead of Unsynchronized.ref;
2010-08-31 ago evaluate takes ml context and ml expression parameter
2010-08-25 ago ML_Context.eval: produce antiquotation environment preferably in invisible context, to avoid displaced report messages from ML_Compiler;
2010-08-08 ago prefer where a proper context is available -- notably for "inner" entities;
2010-05-30 ago replaced ML_Lex.read_antiq by more concise, which includes full read/report with explicit position information;
2010-05-17 ago renamed structure OuterLex to Token and type token to Token.T, keeping legacy aliases for some time;
2010-05-15 ago refer directly to structure Keyword and Parse;
2010-02-07 ago renamed old-style Drule.standard to Drule.export_without_context, to emphasize that this is in no way a standard operation;

2009-10-17 ago indicate CRITICAL nature of various setmp combinators;
2009-09-29 ago explicit indication of Unsynchronized.ref;
2009-06-01 ago structure ML_Compiler;
