2011-08-01 nipkow 2011-08-01 infrastructure for attaching names to hypothesis in cases; realised via the same tag mechanism as case names
2011-07-11 wenzelm 2011-07-11 tuned signature -- corresponding to Scala version;
2011-05-12 wenzelm 2011-05-12 proper configuration options Proof_Context.debug and Proof_Context.verbose; discontinued alias Proof.verbose = Proof_Context.verbose;

2011-04-16 wenzelm 2011-04-16 modernized structure Proof_Context;
2011-04-08 wenzelm 2011-04-08 discontinued special treatment of structure Mixfix; eliminated slightly odd no_syn convenience;
2011-03-21 wenzelm 2011-03-21 tuned;
2011-01-31 wenzelm 2011-01-31 more specific Goal.fork_name;
2010-12-15 wenzelm 2010-12-15 show: display goal refinement rule as "state", to avoid odd Output.urgent_message and make its association with the goal more explicit;
2010-12-04 wenzelm 2010-12-04 formal notepad without any result;
2010-11-22 bulwahn 2010-11-22 added useful function map_context_result to signature

2010-09-09 wenzelm 2010-09-09 more abstract treatment of interrupts in structure Exn -- hardly ever need to mention Interrupt literally;
2010-09-04 wenzelm 2010-09-04 recovered options for goal antiquotations from f45d332a90e3: actually pass context to Proof.pretty_goals (see also 45facd8f358e);
2010-09-03 wenzelm 2010-09-03 pretty_goals: turned some global references and function arguments into configuration options (goals_limit = 10, goals_total = true, show_main_goal = false) depending on the context;
2010-09-03 wenzelm 2010-09-03 Proof.pretty_state: print everything in the foreground context to give users a chance to configure options, e.g. via "using [[show_consts]]";

2010-08-06 wenzelm 2010-08-06 removed obsolete Goal.local_future_enforced: Toplevel.run_command is no longer interactive, so Goal.local_future_enabled is sufficient (cf. 349e9223c685 and e07dacec79e7);
2010-07-24 wenzelm 2010-07-24 moved management of auxiliary theory source files to Thy_Load -- as theory data instead of accidental loader state; theory loader: reduced warnings -- thy database can be bypassed in certain situations; Proof/Local_Theory.propagate_ml_env; ML use function: propagate ML environment as well; pervasive type generic_theory;
2010-05-29 wenzelm 2010-05-29 explicit markup for forked goals, as indicated by Goal.fork; accumulate pending forks within command state and hilight accordingly; Isabelle_Process: enforce future_terminal_proof, which gives some impression of non-linear/parallel checking;
2010-04-29 wenzelm 2010-04-29 'write': actually observe the proof structure (like 'let' or 'fix');
2010-04-29 wenzelm 2010-04-29 ProofContext.read_const: allow for type constraint (for fixed variable); added proof command 'write' to introduce concrete syntax within a proof body;

2010-01-15 berghofe 2010-01-15 Eliminated is_open option of Rule_Cases.make_nested/make_common; use Rule_Cases.internalize_params to rename parameters instead.
2010-01-04 wenzelm 2010-01-04 after_qed: refrain from Position.setmp_thread_data, which causes duplication of results with several independent proof attempts;
