2015-03-10 ago more precise position information in Isabelle/Scala, with YXML markup as in Isabelle/ML;
2015-01-28 ago more robust protocol command: purge removed execs asynchronously, to remain reactive despite problems to cancel "Command.run_process" in a situation of overrunning non-terminating tasks (see also 59f1591a11cb);
2015-01-15 ago refrain from default task_context for all protocol commands, e.g. relevant for "build_theories" to admit Session.shutdown;

2014-04-17 ago added protocol command "use_theories", with core functionality of batch build;
2014-04-07 ago simplified blob again (amending 1e77ed11f2f7): only store file node name, i.e. the raw editor file name;
2014-04-07 ago separate file_node vs. file_path, e.g. relevant on Windows for hyperlink to the latter;
2014-04-03 ago more general prover operations;
2014-03-31 ago support bulk messages consisting of small string segments, which are more healthy to the Poly/ML RTS and might prevent spurious GC crashes such as MTGCProcessMarkPointers::ScanAddressesInObject;
2013-12-11 ago support for polml-5.5.2;
2013-11-22 ago clarified node edits sent to prover -- Clear/Blob only required for text edits within editor;
2013-11-20 ago load files that are not provided by PIDE blobs;
2013-11-19 ago maintain blobs within document state: digest + text in ML, digest-only in Scala;
2013-08-25 ago maintain goal forks as part of global execution;
2013-08-09 ago cancel_query via direct access to the exec_id of the running query process;

2013-08-02 ago maintain overlays within node perspective;
2013-07-31 ago allow explicit indication of required node: full eval, no prints;
2013-07-30 ago tuned signature;
2013-07-29 ago keep memo_exec execution running, which is important to cancel goal forks eventually;

2013-07-29 ago actually purge removed goal futures -- avoid memory leak;
2013-07-29 ago obsolete;
2013-07-15 ago more careful termination of removed execs, leaving running execs undisturbed;
2013-07-12 ago clarified execution: maintain running execs only, check "stable" separately via memo (again);
2013-07-12 ago tuned signature;
2013-07-12 ago clarified module name;
2013-07-11 ago more explicit type Exec.context;
2013-07-11 ago strictly monotonic Document.update: avoid disruptive cancel_execution, merely discontinue_execution and cancel/terminate old execs individually;
2013-07-11 ago tuned -- cleanup before publishing assignment;
