2015-04-15 wenzelm GUI controls for ML_statistics, for more digestible protocol dump;
2015-01-29 wenzelm explicit threads_stack_limit (for recent Poly/ML SVN versions), which leads to soft interrupt instead of exhaustion of virtual memory, which is particularly relevant for the bigger address space of x86_64;

2013-03-27 wenzelm discontinued obsolete parallel_proofs_reuse_timing;
2013-03-27 wenzelm separate option editor_skip_proofs, to avoid accidental change of preferences for skip_proofs, which would invalidate batch builds;

2013-03-13 wenzelm clarified parallel_subproofs_saturation (blind guess) vs. parallel_subproofs_threshold (precient timing estimate);
2013-02-20 wenzelm option parallel_proofs_reuse_timing controls reuse of log information -- since it is not always beneficial for performance;
