added lemmas multp_cancel, multp_cancel_add_mset, and multp_cancel_max

added lemmas multp_implies_one_step, one_step_implies_multp, and subset_implies_multp

added lemma wfP_multp

added lemma mono_multp

added Multiset.multp as predicate equivalent of Multiset.mult

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

more robust build on midrange hardware;

clarified tests: omit somewhat pointless (unstable) results;

proper fields for gnuplot (amending b614e3e4146a);

tuned output;

merged

more robust build on midrange hardware (despite 67d6f1708ea4);

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

renamed multp_code_iff and multeqp_code_iff

simplified mult_cancel_max and introduced orginal lemma as mult_cancel_max0

renamed Multiset.multp and Multiset.multeqp
