tuned comments;

standard Graph instances;

clarified signature -- avoid oddities of Iterable like Iterator.map; specific toString;

discontinued slightly odd Graph.del_nodes (inefficient due to full Table.map);

moved predicate relations and conversion rules between set and predicate relations from Predicate.thy to Relation.thy; moved Predicate.thy upwards in theory hierarchy

explicit is better than implicit

dropped dead code

prefer sorted Map/Set for canonical order of results -- pass ordering via fresh copy of empty; discontinued map_nodes, del_nodes conveniences -- avoid inefficient mapValues wrapper (this is not Table.map from ML); tuned signature;

tuned imports;

tuned signature;

discontinued obsolete Graph.all_paths (last seen in 1524d69783d3 and AFP/80bbbdbfec62);

merged

remove ill-formed lemmas word_0_wi_Pls and word_m1_wi_Min

avoid using Int.succ_def in proofs

avoid using Int.succ or Int.pred in proofs

avoid using BIT_simps in proofs; rephrase lemmas without Int.succ or Int.pred;

avoid using BIT_simps in proofs

updated stats according to src/HOL/IsaMakefile;

more precise clean target;

clarifed name space "type name", which covers logical and non-logical types, and often occurs inside outer syntax "type" markup;

avoid using Int.Pls_def in proofs

remove ill-formed lemmas word_pred_0_Min and word_m1_Min

remove ill-formed lemma of_bl_no; adapt proofs

adapt lemma mask_lem to respect int/bin distinction

rephrase some slow "metis" calls

added support for Alt-Ergo through Why3 (mostly for experimental purposes, e.g. polymorphism vs. monomorphization)

general solution to the arity bug that occasionally plagues Sledgehammer -- short story, lots of things go kaputt when a polymorphic symbol's arity in the translation is higher than the arity of the fully polymorphic HOL constant

renamed 'try_methods' to 'try0'
