2011-04-08 ago explicit structure Syntax_Trans;

2011-03-22 ago enable inner syntax source positions by default (controlled via configuration option);
2010-12-21 ago configuration option "syntax_ast_trace" and "syntax_ast_stat";
2010-12-21 ago configuration option "ML_trace";
2010-12-17 ago renamed structure MetaSimplifier to raw_Simplifer, to emphasize its meaning;
2010-12-16 ago turned simp_trace_depth_limit into a configuration option
2010-12-02 ago configuration option "show_abbrevs" supersedes print mode "no_abbrevs", with inverted meaning;

2010-10-30 ago support for real valued configuration options;
2010-09-20 ago renamed structure PureThy to Pure_Thy and moved most content to Global_Theory, to emphasize that this is global-only;

2010-09-06 ago turned show_hyps and show_tags into proper configuration option;
2010-09-06 ago more explicit indication of Config.raw options, which are only needed for bootstrapping Pure;
