sort E weights

added support for bleeding-edge E weighting function "SymOffsetsWeight"

transformed lie into truth

enable SMT weights and triggers, since they lead to slight improvements according to the Judgment Day suite

improving sum type and option type term constructions for correct presentation in Smallcheck

Explicitly build HOLCF and ZF images. They are not part of the release any more.

added termination lemmas

improving term construction of product types in Smallcheck which enables correct presentation of counterexamples

discontinued support for Poly/ML 5.2, which was the last version without proper multithreading and TimeLimit implementation;

tuned headers;

updated to polyml-5.3.0, which is presently known as the most robust version;

explicit Multithreading.interrupted to ensure that interrupts stay within the boundaries of managed evaluation blocks;

always test/clear Multithreading.interrupted, indepently of thread attributes; tuned;

added Multithreading.interrupted (cf. java.lang.Thread.interrupted);

more robust TimeLimit: make double sure that watchdog has terminated and interrupts received during uninterruptible state are propagated (NB: Thread.testInterrupt requires InterruptSynch in Poly/ML 5.4.0 or earlier);

more tracing information via Par_List.map_name;

clarified bootstrapping of structure TimeLimit;

more scalable collections of tasks, notably for totality of known group members; tuned;

tuned signature; tuned;

merged

prefer p2e before e2p; use measure_unique_Int_stable_vimage;

add auto support for AE_mp

add borel_fubini_integrable; remove unused bijectivity rules for measureable functions

parallelization of nested Isar proofs is subject to Goal.parallel_proofs_threshold;

Task_Queue.update_timing: more precise treatment of interruptibility; Task_Queue.waiting: potentially expensive wait dependencies are subject to trace flag;

Lazy.force_result: more standard treatment of interruptibility, potentially addressing races of exceptions vs. interrupts;

thm_proof: visible fulfill_body only, without joining nested thms -- retain proof irrelevance, which is important for parallel performance;

tuned comments;

clarified Proofterm.proofs_enabled;

explicit is better than implicit;

tuned odd conditional expression;

eliminated slightly odd abstract type Task_Queue.deps; tuned signature; tuned;

merged

Introduction of metis calls and other cosmetic modifications.

merged

avoid ML structure aliases (especially single-letter abbreviations)

making the bash script swipl_version closer to Isabelle's conventional bash scripts

the measure valuation is again part of the measure_space type, instead of an explicit parameter to the locale; changed syntax for simple_function, simple_integral, positive_integral, integral and RN_deriv. introduced binder variants for simple_integral, positive_integral and integral.

merged

scala serializer adds parentheses around function literals

made SML/NJ happy

term style 'isub': ad-hoc subscripting of variables that end with digits (x1, x23, ...)

refined Task_Queue.dequeue_deps (more incremental);

maintain Task_Queue.group within Task_Queue.task; Task_Queue.dummy_task: id = 0 in accordance to Document.no_id etc.; tuned signature;

tuned comment;

Future.join_results: discontinued post-hoc recording of dynamic dependencies; abstract Task_Queue.deps; tuned signature; tuned;

more informative task timing: some dependency tracking;

refined task timing: joining vs. waiting; tuned;

simplified trace;

more specific Goal.fork_name;

name "passive" tasks (practically lazy values);

tuned trivial cases;

tuned signature; tuned vacous forks;

support named tasks, for improved tracing;

more direct Future.bulk, which potentially reduces overhead for Par_List; tuned signature;
