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;

2011-01-31 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

2010-08-06 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');

2010-01-15 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;
2009-11-02 wenzelm 2009-11-02 modernized structure Proof_Display;
2009-11-02 wenzelm 2009-11-02 modernized structure AutoBind;

2009-10-02 wenzelm 2009-10-02 clarified Proof.refine_insert -- always "refine" to apply standard method treatment (of conjunctions);
2009-09-30 wenzelm 2009-09-30 eliminated dead code;
2009-09-30 wenzelm 2009-09-30 replaced chained_goal by slightly more appropriate flat_goal;
2009-09-30 wenzelm 2009-09-30 added chained_goal, which presents the goal thm as seen by semi-structured methods;
2009-09-29 wenzelm 2009-09-29 explicit indication of Unsynchronized.ref;
2009-07-25 wenzelm 2009-07-25 basic method application: avoid Position.setmp_thread_data_seq, which destroys transaction context; Method.Basic: no position;
2009-07-25 wenzelm 2009-07-25 renamed structure Display_Goal to Goal_Display;
2009-07-24 wenzelm 2009-07-24 Display_Goal.pretty_goals: always Markup.subgoal, clarified options;
2009-07-23 wenzelm 2009-07-23 clarified pretty_goals, pretty_thm_aux: plain context; explicit pretty_goals_without_context, print_goals_without_context; tuned;
2009-07-21 wenzelm 2009-07-21 proper context for Display.pretty_thm etc. or old-style versions Display.pretty_thm_global, Display.pretty_thm_without_context etc.;
2009-07-20 wenzelm 2009-07-20 moved pretty_goals etc. to Display_Goal (required by tracing tacticals); load display.ML after assumption.ML, to accomodate proper contextual theorem display;
2009-07-20 wenzelm 2009-07-20 Proof.future_proof: declare all assumptions as well; Proof.future_proof: removed spurious exception_trace (which might cause crash-by-interrupt); replaced Future.fork_local by Future.fork_pri (again, until group exceptions are propagated properly);
2009-07-19 wenzelm 2009-07-19 parallel_proofs: more fine-grained control with optional parallel checking of nested Isar proofs;
2009-07-19 wenzelm 2009-07-19 more abstract Future.is_worker; Future.fork_local: inherit from worker (if available);
