Changelog for coq-doc-8.19.2-1.2.noarch.rpm :

* Sun Jun 30 2024 Aaron Puchert - Update to version 8.19.2.
* Fixed a regression from Coq 8.18 in the presence of a defined field in a primitive `Record`.
* Fixed an issue where the printer was sometimes failing to use a prefix or infix custom notation whose right-hand side refers to a different custom entry.
* Fixed `abstract` failure in the presence of admitted goals in the surrounding proof.
* Fixed issues when using Ltac2 in VsCoq due to incorrect state handling of Ltac2 notations.
* Fixed `Include` on a module containing a record declared with `Primitive Projections`.
* Fixed an issue in `Fixpoint` with no arguments.
* Position error/warning tooltips correctly when multibyte UTF-8 characters are present.
* Thu Mar 07 2024 Aaron Puchert - Update to version 8.19.1.
* Fixed incorrect abstraction of sort variables for opaque constants leading to an inconsistency.
* Fixed memory corruption with `vm_compute` (rare but more likely with OCaml 5.1).
* \"Found no matching notation to enable or disable\" is now a warning instead of an error.
* Fixed undeclared universe with multiple uses of `abstract`.
* Fixed incorrect printing of constructor values with multiple arguments, and over-parenthesizing of constructor printing.
* Fixed incorrect declared type for Ltac2.FMap.fold.
* Sun Jan 28 2024 Aaron Puchert - Update to version 8.19.0. The most impactful changes:
* Sort polymorphism makes it possible to share common constructs over `Type`, `Prop` and `SProp`.
* The notation `term%_scope` to set a scope only temporarily (in addition to `term%scope` for opening a scope applying to all subterms).
* `lazy`, `simpl`, `cbn` and `cbv` and the associated `Eval` and `eval` reductions learned to do head reduction when given flag `head`.
* New Ltac2 APIs, improved Ltac2 `exact` and dynamic building of Ltac2 term patterns.
* New performance evaluation facilities: `Instructions` to count CPU instructions used by a command and Profiling system to produce trace files.
* New command `Attributes` to assign attributes such as `deprecated` to a library file.- Notable breaking changes:
* `replace` with `by tac` does not automatically attempt to solve the generated equality subgoal using the hypotheses. Use `by first [assumption | symmetry;assumption | tac]` if you need the previous behaviour.
* Removed old deprecated files from the standard library.- Use %fdupes in the documentation package.
* Sun Nov 12 2023 Aaron Puchert - Revert last change: this is now set in ocaml-rpm-macros.- Increase stack size limit in QEMU user space builds. Here ulimit has no effect, so we add a wrapper around ocamlopt.opt to PATH that adds \"-s ...\" to the qemu- command line.
* Mon Oct 30 2023 Aaron Puchert - Increase stack size limit to fix build on riscv64.
* Sat Sep 16 2023 Aaron Puchert - Update to version 8.18.0.
* The default locality of `Hint` and `Instance` commands was switched to `export`.
* The universe unification algorithm can now delay the commitment to a sort (the algorithm used to pick `Type`). Thanks to this feature many `Prop` and `SProp` annotations can be now omitted.
* Ltac2 supports array literals, maps and sets of primitive datatypes such as names (of constants, inductive types, etc) and fine-grained control over profiling.
* The warning system offers new categories, enabling finer (de)activation of specific warnings. This should be particularly useful to handle deprecations.
* Many new lemmas useful for teaching analysis with Coq are now part of the standard library about real numbers.
* The `#[deprecated]` attribute can now be applied to definitions.
* Wed Jun 28 2023 Aaron Puchert - Update to version 8.17.1.
* Fixed incorrect paths emitted by coqdep in some cases for META files which prevented dune builds for plugins from working correctly.
* Fixed shadowing of record fields in extraction to OCaml.
* Fixed an impossible-to-turn-off debug message \"backtracking and redoing byextend on ...\".
* Fixed a major memory regression affecting MathComp 2.- Classify desktop entry under Science instead of Education.- Add screenshot URL to AppStream metadata.
* Tue Mar 28 2023 Aaron Puchert - Update to version 8.17.0.
* Fixed a logical inconsistency due to `vm_compute` in presence of side-effects in the enviroment (e.g. using Back or Fail).
* It is now possible to dynamically enable or disable notations.
* Support multiple scopes in `Arguments` and `Bind Scope`.
* The tactics chapter of the manual has many improvements in presentation and wording. The documented grammar is semi- automatically checked for consistency with the implementation.
* Fixes to the `auto` and `eauto` tactics, to respect hint priorities and the documented use of simple apply. This is a potentially breaking change.
* New Ltac2 APIs, deep pattern-matching with `as` clauses and handling of literals, support for record types and preterms.
* Move from :> to :: syntax for declaring typeclass fields as instances, fixing a confusion with declaration of coercions.
* Standard library improvements.
* Thu Jan 26 2023 Aaron Puchert - Build with ocaml-rpm-macros to get proper Requires and Provides for coq-devel. This should prevent incompatibilities with other Ocaml libraries when building native objects against coq-devel.
* Sat Nov 26 2022 Aaron Puchert - Update to version 8.16.1.
* Fixed the conversion of `Prod` values in the native compiler.
* Added `SProp` check for opaque names in conversion.
* Pass the correct environment to compute η-expansion of cofixpoints in VM and native compilation.
* Fixed an inconsistency with conversion of primitive arrays, and associated incomplete strong normalization of primitive arrays with `lazy`.
* `Print Assumptions` treats opaque definitions with missing proofs (as found in .vos files, produced using -vos) as axioms instead of ignoring them.
* Thu Sep 08 2022 Aaron Puchert - Update to version 8.16.0.
* The guard checker (see `Guarded`) now ensures strong normalization under any reduction strategy.
* Irrelevant terms (in the `SProp` sort) are now squashed to a dummy value during conversion, fixing a subject reduction issue and making proof conversion faster.
* Introduction of reversible coercions, which allow coercions relying on meta-level resolution such as type-classes or canonical structures. Also allow coercions that do not fullfill the uniform inheritance condition.
* Generalized rewriting support for rewriting with `Type`-valued relations and in `Type` contexts, using the `Classes.CMorphisms` library.
* Added the boolean equality scheme command for decidable inductive types.
* Added a `Print Notation` command.
* Incompatibilities in name generation for Program obligations, `eauto` treatment of tactic failure levels, use of `ident` in notations, parsing of module expressions.
* Standard library reorganization and deprecations.
* Improve the treatment of standard library numbers by `Extraction`.- Coq requires ocamlfind at runtime now.
* Wed Jun 01 2022 Aaron Puchert - Update to version 8.15.2.
* Tactics `intuition` and `dintuition` use `Tauto.intuition_solver` (defined as `auto with
*`) instead of hardcoding `auto with
*`. This makes it possible to change the default solver with `Ltac Tauto.intuition_solver ::= ...`.
* Fixed an uncaught exception `UnableToUnify` with bidirectionality hints.
* Fixed multiple CoqIDE bugs.
* Fixed an incorrect implementation of `SFClassify`, allowing for a proof of `False` since 8.11.0, due to Axioms present in `Float.Axioms`.- Rename coq.desktop to fr.inria.coq.coqide.desktop as the documentation suggests, add an accompanying metainfo file.- Declare documentation as noarch.
* Thu Mar 24 2022 Aaron Puchert - Update to version 8.15.1.
* Fixes an inconsistency when using module subtyping with inductive types.
* Speeds up CoqIDE on large files.
* Fixes a bug where `coqc -vok` was not creating a .vok file.
* Fixes a regression in `cbn`.
* Improves usability of schemes with `elim foo using scheme with (P0 := ...)` (the `P0` name was not accessible in 8.15.0).
* Sat Jan 15 2022 Aaron Puchert - Update to version 8.15.0.
* The `apply with` tactic no longer renames arguments unless the compatibility flag `Apply With Renaming` is set.
* Improvements to the `auto` tactic family, fixing `Hint Unfold` behavior, and generalizing the use of discrimination nets.
* The `typeclasses eauto` tactic has a new `best_effort` option allowing it to return partial solutions to a proof search problem, depending on the mode declarations associated to each constraint. This mode is used by typeclass resolution during type inference to provide more precise error messages.
* Many commands and options were deprecated or removed after deprecation and more consistently support locality attributes.
* The `Import` command is extended with `import_categories` to select the components of a module to import or not, including features such as hints, coercions, and notations.
* A visual Ltac debugger is now available in CoqIDE.
* For more details, see refman/changes.html in coq-doc.
* Sun Dec 12 2021 Aaron Puchert - Update to version 8.14.1.
* Fixed the implementation of persistent arrays used by the VM and native compute so that it uses a uniform representation. Previously, storing primitive floats inside primitive arrays could cause memory corruption.
* Fixed missing registration of universe constraints in Module Type elaboration.
* Made `abstract` more robust with respect to Ltac `constr` bindings containing existential variables.
* Correct support of trailing `let` by tactic `specialize`.
* Fixed an anomaly with `Extraction Conservative Types` when extracting pattern-matching on singleton types.
* Regular error instead of an anomaly when calling `Separate Extraction` in a module.
* Wed Oct 20 2021 Aaron Puchert - Update to version 8.14.0.
* The internal representation of match has changed to a more space-efficient and cleaner structure, allowing the fix of a completeness issue with cumulative inductive types in the type- checker. The internal representation is now closer to the user- level view of match, where the argument context of branches and the inductive binders in and as do not carry type annotations.
* A new coqnative binary performs separate native compilation of libraries, starting from a .vo file. It is supported by coq_makefile.
* Improvements to typeclasses and canonical structure resolution, allowing more terms to be considered as classes or keys.
* More control over notations declarations and support for primitive types in string and number notations.
* Removal of deprecated tactics, notably omega, which has been replaced by a greatly improved lia, along with many bug fixes.
* New Ltac2 APIs for interaction with Ltac1, manipulation of inductive types and printing.
* Many changes and additions to the standard library in the numbers, vectors and lists libraries. A new signed primitive integers library Sint63 is available in addition to the unsigned Uint63 library.
* For more details, see refman/changes.html in coq-doc.
* Sat Sep 04 2021 Aaron Puchert - Add documentation package based on github.com/coq/doc until we can build the documentation directly in OBS.
* Mon Apr 12 2021 Aaron Puchert - Update to version 8.13.2.
* Fix crash when using vm_compute on an irreducible PArray.set.
* Fix crash when loading .vo files containing a vm_compute normalized primitive array.
* Fix Ltac2.Array.init computational complexity.
* Thu Feb 25 2021 Aaron Puchert - Update to version 8.13.1.
* Fix arities of VM opcodes for some floating-point operations that could cause memory corruption.
* Sun Feb 07 2021 Aaron Puchert - Update to version 8.13.0.
* Introduction of primitive persistent arrays in the core language, implemented using imperative persistent arrays.
* Introduction of definitional proof irrelevance for the equality type defined in the SProp sort.
* Cumulative record and inductive type declarations can now specify the variance of their universes.
* Various bugfixes and uniformization of behavior with respect to the use of implicit arguments and the handling of existential variables in declarations, unification and tactics.
* New warning for unused variables in catch-all match branches that match multiple distinct patterns.
* New warning for Hint commands outside sections without a locality attribute, whose goal is to eventually remove the fragile default behavior of importing hints only when using Require. The recommended fix is to declare hints as export, instead of the current default global, meaning that they are imported through Require Import only, not Require.
* General support for boolean attributes.
* Many improvements to the handling of notations, including number notations, recursive notations and notations with bindings. A new algorithm chooses the most precise notation available to print an expression, which might introduce changes in printing behavior.
* Tactic improvements in lia and its zify preprocessing step, now supporting reasoning on boolean operators such as Z.leb and supporting primitive integers Int63.
* Typing flags can now be specified per-constant / inductive.
* Improvements to the reference manual including updated syntax descriptions that match Coq\'s grammar in several chapters, and splitting parts of the tactics chapter to independent sections.- Add build flag to turn off building of the IDE.
