more documentation about Type/Const antiquotations;

more documentation about document build options;

address problems with launch4j and jdk-17 (see also 41d009462d3c, copy of 41d009462d3c);

tuned --- fewer IDE warnings;

more robust physical timeout (despite 1bea05713dde), especially relevant for quickcheck where large unary numerals may cause excessive heap allocations and resulting GC is better included in the timing;

added definitions multp{DM,HO} and corresponding lemmas

added wfP_less to wellorder and wfP_less_multiset

restored lemmas less_multiset{DM,HO} inadvertently changed by c256bba593f3

Added tag Isabelle2021-1-RC4 for changeset 2336356d4180

updated to polyml-5.9;

NEWS on "isabelle mirabelle";

tuned;

clarified default for kodkod_scala; NEWS for proper release;

maintain option kodkod_scala within theory context, to allow local modification;

NEWS for proper release;

updated to flatlaf-1.6.4;

avoid broken links: auxiliary files are not yet supported;

option document_comment_latex supports e.g. Dagstuhl LIPIcs;

more explicit type Latex.Tags; generate isabelletags.sty from Isabelle/Scala, including comment.sty setup;

more uniform treatment of optional_argument for Latex elements; discontinued somewhat pointless element position in Isabelle/Scala: semantic add-ons are better provided in Isabelle/ML; clarified signature of class Latex: overridable unknown_elem allows to extend the markup language;

removed pointless 'text_cartouche' command: regular 'text' already supports cartouches;

example: alternative document headings, based on more general document output markup;

more general document output: enclosing markup is defined in user-space;

clarified modules (see c299abcf7081);

output for document commands like 'section', 'text' is defined in user-space, as part of the command transaction;

clarified modules;

tuned signature: more explicit types for presentation;

more robust support for Windows line-endings;

source positions for document markup commands, e.g. to retrieve PIDE markup in presentation;

more compact data during presentation: Entity_Context.Theory_Export instead of full Export_Theory.Theory;

clarified system option standard values: avoid oddities like "isabelle build -o document_output" producing directories named "true";

more symbolic latex_output via XML (using YXML within text);

proper enclose_name (amending e77c5bfca9aa);

Latex.Output.latex_heading depends on option document_heading_prefix, e.g. relevant for Dagstuhl LIPIcs which prefers unaliased \section etc.;

more symbolic latex_output via XML;

clarified hook for Mirabelle (again): cover all 'theories' sections within ROOT (see also 9ead8d9be3ab);

tuned;

tuned;

updated to verit-2021.06.2-rmx;

clarified HTML_Context.theory_exports: prefer value-oriented parallelism;

generate problems with correct logic for veriT

more parallelism, at the cost of potential duplicates of make_thy;

afford more parallelism for sessions (instead of theories in 5eac4b13d1f1): depend on disjoint data areas (notably base.session_theories in 2ad892ac749a);

more interrupts;

present only selected session theories (as in Isabelle2021), in contrast to 2bc24136bdeb, eb89b3a37826; eliminated implicit state: these theories are globally unique;

tuned;

clarified modules;

tuned (see also e0d1d9203275);

clarified signature;

tuned;

spelling;

added asymp_{less,greater} to preorder and moved mult1_lessE out

simplified mult_cancel_max and introduced orginal lemma as mult_cancel_max0

renamed Multiset.multp and Multiset.multeqp

added lemmas

merged

tuned;

removed redundant test (see also 86fac52c2795, a9fea3f11cc0);

just one Presentation.State for all sessions: avoid duplication of already presented theories (very slow) and cached theory export (not very slow);

proper version;

back to Z3 4.4.0pre for all platforms except arm64-linux: avoid failure e.g. in Padic_Ints (AFP/7a2522dce834);

less ambitious parallelism: more direct read/write saves overall heap space and GC time;

slightly faster XML output: avoid too much regrowing of StringBuilder;

updated NEWS: arm64-linux support is almost complete;

update z3-4.4.0pre-3 to z3-4.4.1, which happens to have an arm64_linux executable in Debian 9;

more material for HOL-Analysis.Infinite_Sum

more symbolic latex_output via XML;

clarified signature;

updated to polyml-5.9-610a153b941d -- close to final;

tuned signature (again): latex_output is likely to depend on context;

more symbolic latex output; discontinued Latex.output_text, which is in conflict with symbolic output;

tuned signature;

symbolic latex_output via XML, interpreted in Isabelle/Scala;

tuned signature;

clarified signature;

clarified signature;

A tiny bit of tidying connected with Zorn's Lemma

tuned;

tuned;

proper handling of Protocol.Export, using the payload from the message --- in contrast db_context.read_export materializes only later by a different thread (race condition);

revert temporary workaround 6d111935299c;

added lemma

merged

tuned attributes to avoid looping

added eq_iff_swap for creating symmetric variants of thms; applied it in List.

proper java_version for isabelle_setup;

explicit option metric_argo_timeout, with reasonable default for Raspberry Pi;

tuned;

repackage minisat-2.2.1 with cygwin1.dll: required to run the executable without existing Cygwin context (normally provided by bash_process);

clarified messages, depending on option "document_echo";

just one cache, via HTML_Context, via Sessions.Store or Session;

merged

more precise URL

tuned page breaks

cover all possible kinds, notably for references outside of this theory (amending 129fb11b357f);

proper foundational order;

back to non-strict Export_Theory.read_theory (without warning): theories could have been skipped due to "condition";

use all entity kinds from theory export, e.g. "method", "attribute";

clarified signature;

clarified physical_ref;

proper treatment of session build hierarchy;

proper used_theories for session build hierarchy, not known_theories from imported sessions;

present theories from imported sessions as required;

proper term_cache;

prefer "NAME|KIND" format, as already used in Isabelle/MMT and Isabelle/Dedukti;

observer proper session hierarchy (according to build_graph): thus exported artifacts are always valid;

tuned;

clarified order: prefer bottom-up construction of partial content;

more thorough update_global_index: overwrite old content;

tuned;

tuned;

clarified HTML_Context: just one context type;

unused (see also 217e6cf61453, 5e7916535860);

tuned whitespace;

updated to verit-2021.06.1-rmx, to address "Abnormal termination with exit code 14";

prefer official Export.explode_name; avoid string interpolation: Isabelle/Scala is closer to Isabelle/ML than Python/Perl;

tuned;

avoid conflict with future keyword;

tuned messages;

clarified signature: more direct XML.symbol_length;

more direct Symbol.length: Symbol.decode is redundant, symbol counts are invariant under it;

do not declare $let-bound variables in TPTP output

IDE build actually works (but somewhat pointless);
