2017-04-07 ago provide session base for "isabelle build" and "isabelle console" ML process;
2017-02-27 ago absent timing information means zero, according to 0070053570c4, f235646b1b73;
2016-08-12 ago uniform ML and document antiquotations;
2016-08-12 ago clarified error;

2014-12-09 ago imitate command markup and rendering of Isabelle/jEdit in HTML output;
2014-12-03 ago tuned signature;
2014-11-07 ago prefer externally provided keywords -- Command.read_thy may degenerate to bootstrap_thy in case of errors;
2014-11-07 ago plain value Keywords.keywords, which might be used outside theory for bootstrap purposes;

2014-11-01 ago tuned signature, in accordance to Scala version;
2014-10-31 ago obsolete;

2014-04-30 ago clarified signature: load_file is still required internally;
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;
2014-03-26 ago prefer Context_Position where a context is available;
2014-03-26 ago superseded by (provide_)parse_files;
