HTML: render control symbols more like Isabelle/Scala/jEdit;

collapse map functions with identity subcoercions to identities;

reenabled accidentally-disabled automatic minimization

tuned markup;

tidied messy proofs

adding timeout to quickcheck narrowing

simplified proofs using metis calls

keyfree: The set of key-free messages (and associated theorems)

merged

new Datatype.info_of_constr with strict behaviour wrt. to overloaded constructors -- side effect: function package correctly identifies 0::int as a non-constructor; renamed old version to info_of_constr_permissive, reflecting its semantics

added reference for MESON

document "meson" and "metis" in HOL specific section of the Isar ref manual

clarify minimizer output

don't export any metastrange or other nonatomizable formulas, since these don't help proving normal things, they are somewhat broken in the ATP output, and they are atypical

tweaked comment

document "sound" option

minor Sledgehammer news

added "sound" option to force Sledgehammer to be pedantically sound

removed "full_types" option from documentation

document changes to Sledgehammer and "try"

removed "full_types" option from Sledgehammer, now that virtually sound encodings are used as the default anyway

clarify warning message to avoid confusing beginners

remove experimental trimming feature -- it slowed down things on Linux for some reason

filter out some tautologies using an ATP, especially for those theories that are known for producing such things

NEWS;

document antiquotations are managed as theory data, with proper name space and entity markup;

proper checking of @{ML_antiquotation};

hide rather short auxiliary names, which can easily occur in user theories;

updated generated file;

ML antiquotations are managed as theory data, with proper name space and entity markup; clarified Name_Space.check;

old gensym is now legacy -- global state is out of fashion, and its result is not guaranteed to be fresh;

parallel Syntax.parse, which is rather slow;

markup binding like class, which is the only special markup where Proof General (including version 4.1) allows "isar-long-id-stuff";

move conditional expectation to its own theory file

updated SMT certificates

generalized introduction of explicit application constant: consider more functions as possible witness/instance of quantifiers than before (a constant of type T1 -> T2 -> T3 should be considered to have a rank less or equal to 1 if variables of type T2 -> T3 occur bound in a problem); maintain extra-logical information when introducing explicit application; handle let-expressions properly

proper tokens only if session is ready;

entity markup for "type", "constant";

clarified Markup.CLASS vs. HTML.CLASS;

tuned color, to avoid confusion with type variables;

discontinued generic XML markup -- this is for XHTML with <span/> elements;

type classes: entity markup instead of old-style token markup;

clarified Binding.pretty/print: no quotes, only markup -- Binding.str_of is rendered obsolete;

clarified Binding.str_of/print: show full prefix + qualifier, which is relevant for print_locale, for example; discontinued unused Binding.qualified_name_of;

produce string constant directly;

merged

While reading equations of an interpretation, already allow syntax provided by the interpretation base.

removed very slow proof of unnamed/unused theorem from HOL/Quickcheck_Narrowing.thy (cf. 2dee03f192b7) -- can take seconds for main HOL and minutes for HOL-Proofs;

clarified java.ext.dirs: putting Isabelle extensions first makes it work miraculously even on Cygwin with Java in "C:\Program Files\..." (with spaces in file name);

CLASSPATH already converted in isabelle java wrapper;

removed unused/broken Isabelle.exe for now -- needs update of Admin/launch4j;

more robust join_results: join_work needs to be uninterruptible, otherwise the task being dequeued by join_next might be never executed/finished!

clarified EXCEPTIONS [] (cf. Exn.is_interrupt and Runtime.exn_message);

more robust concurrent builds;

merged

add countable_datatype method for proving countable class instances
