avoid deprecated Scala syntax;

enforce case of identifiers only to accomodate strict language requirements (or clear separation of constructors from variables in the case of SML)

more standard doc session specification;

discontinued adhoc check (see also ea8343187225);

more frugal access to theory text via Reader, reduced costs for I/O text decoding; prefer non-strict Symbol.decode, since Reader[Char] may present symbols in either way;

support URLs as well;

reclaimed Byte_Reader from 51560e392e1b;

new documentation: How to Prove it

disable bad Z3 proof

use SMT2 for Boogie examples

less verbose SAT tactic

use internal proof-producing SAT solver for more efficient SMT proof replay

added internal proof-producing SAT solver

tuned output;

separate ML module

centralized upper/lowercase name mangling

optional case enforcement

obsolete: no symbol identifiers remaining in Pure

prevent subscription in nested contexts explicitly -- at foundational and user level

cleanup

NEWS

use qualified name (was interpreted as a catch-all variable name)

add additional check to avoid selector formula right-hand side consisting of a nullary constructor getting interpreted as a discriminator formula

updated keywords;

clarified signature: load_file is still required internally;

merged

some support for session-qualified theories: allow to refer to resources via qualified name instead of odd file-system path;

support for long names in Scala;

tuned;

Discontinued old spark_open; spark_open_siv is now spark_open

suppress slightly odd completions of "real";

tuned proofs;

tuned proofs;

clarified exit sequence: prover is reset afterwards, no more output messages;

more synchronized treatment of prover process, which might emit more messages before shutdown and requires manager to accept them;

tuned;

some sanity checks for Isabelle sources;

prefer plain ASCII / latex over not-so-universal Unicode;

tuned whitespace;

proper Unix line termination;

require explicit 'document_files';

updated mkroot;

basic support for Mercurial command line tools;

clarified;

ignore malformed file names outright, e.g. .class files with dollar;

more systematic Isabelle output, like in classic Isabelle/ML (without markup);

systematic replacement of 'files' by 'document_files';

tuned signature -- accomodate operations of ROOT files;

tuned -- prefer Isabelle/Scala operations;

tuned proofs;

tuned;

tuned proofs;

improved syslog performance -- avoid denial-of-service e.g. with threads_trace = 5 and active Syslog dockable;

tuned -- fewer aliases of critical operations;

removed dead code; tuned comments;

tuned comments;

more systematic delay_first discipline for change_buffer and prune_history;

mane delayed events outside of Swing thread -- triggers no longer require Swing_Thread.later;

tuned;

added Scala version of module Event_Timer;
