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

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;

clarified signature: more privacy;

tuned output --- less redundancy;

tuned whitespace;

clarified signature: Latex.Output as parameter to Document_Build.Engine; tuned;

proper detection of ARM platform variants;

back to post-release mode;

updated for release;

Added tag Isabelle2021-1-RC3 for changeset 2b212c8138a5

updated to polyml-5.9-cc80e2b43c38, which also contains ARM64 on darwin (unused by default);

clarified HTML_Context: more explicit directory structure;

tuned comments;

tuned;

clarified signature;

clarified properties: avoid empty entry;

tuned signature;

merged

tuned (thanks to J. Villadsen)

added padding to Mirabelle's output

merged

tuned generation of TPTP with $ite/$let in higher-order logics

tuned generation of TPTP with $ite in function position

tuned TPTP generation of If helper facts

merged

clarified signature: prefer static operations;

clarified signature: avoid potential misunderstanding of Resources.empty as proper Resources;

more robust;

tuned signature;

clarified signature: more explicit class Entity_Context with private state + operations;

more hyperlinks, notably internal fact references;

Automated merge with bundle:/var/folders/9z/l1x9y3bd16x9_70pdp4703jr0000gp/T/SourceTreeTemp.14UUXO

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.

tuned text;

more robust timeout, following df4449c6eff1;

more accurate Files.isRegularFile, exclude directories (e.g. jar_path);

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);

discontinued redundant document_preprocessor: in the worst case, a plain-old document/build script will do;

clarified messages, depending on option "document_echo";

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