General information

See README for general information and installation of Coq Platform.

See Charter for the concept and goals of Coq Platform.

See CEP52 for the Coq and Coq Platform release cycle.

Major enhancements

The latest release version of Coq has been updated from 8.15.1 to 8.15.2 (see Coq 8.15.2 release notes). This is a bug fix release with a few important fixes:

  • Various issues introduced in CoqIDE by the implementation of the Ltac Debugger have been fixed, most notably a quadratic blow up in parsing time.
  • A wrong standard library axiom for the native float implementation allowed a proof of false.

Included Versions of Coq

Recommended Coq version

Compatibility Coq versions

The compatibility versions are intended to help porting packages from an older to the latest release. They can be installed in parallel with other versions of Coq (Coq Platform will create separate opam switches for each Coq version).

  • Coq 8.14.1 with an updated package collection from Apr 2022 - this package pick is made to be as compatible as possible with the 8.15.2 package collection
  • Coq 8.14.1 with the first package collection from Jan 2022
  • Coq 8.13.2 with an updated package collection from January 2022 - this package pick is made to be as compatible as possible with the first 8.14.1 package collection
  • Coq 8.13.2 with an updated package collection from September 2021
  • Coq 8.13.2 with the original package collection from February 2021
  • Coq 8.12.2 with the same package collection as the 8.12.2 Coq Platform release

Only the 8.14.1 and the 8.15.2 version are available as installers for macOS and Windows and only the 8.15.2 version as snap package. Other versions can be installed using the Coq Platform scripts.

Notes

  • Notes on the macOS installer: This installer is only compatible with macOS 11.0 or higher. Because the application is signed but not "notarized", it won't open by default, unless you right-click the application in Finder and chose Open. Cf. #51 to learn more.

  • Notes on Apple ARM silicon: Coq Platform has been tested by users on Apple silicon (M1), but we have no means to run CI tests on Apple silicon (yet), so this not officially supported. We appreciate bug reports for Apple silicon, but we will ask you for help fixing them.

  • Notes on CoqHammer: The proof generation component of CoqHammer is available on macOS and Linux only. The CoqHammer tactics, which reconstruct generated proofs, do work on Windows, though. Since the CoqHammer tactic running on macOS and Linux creates simple and fast Coq tactic call snippets which are intended to replace the slow generator tactics, it is possible to use the auto generated tactics on Windows as well. Also you can manually write CoqHammer tactic calls (that is use it as replacement for auto) on Windows.

  • Note on Flocq: there is a new version 4.0 for coq-flocq which is not compatible with the previous 3.X versions. Since some packages are not yet compatible with Flocq 4.0, notably coq-compcert, the 2022.04 picks contain both, coq-flocq.4.0.0 and coq-flocq.3.4.3. Since one cannot install two version of one package, a new package called coq-flocq3 has been added which uses Flocq3 rather than Flocq as logical path. This way Flocq 3.X can be selected by using Flocq3 in the Require commands and Flocq 4.X can be selected by using Flocq in the Require commands. The package coq-compcert has been patched to require Flocq3. For convenience the proof automation packages used for float proofs, coq-gappa and coq-interval are also available in a Flocq 3.X and Flocq 4.X variant. The Flocq 4.X variants have the usual logical path, the 3.X variants use the logical paths IntervalFlocq3 and GappaFlocq3. The Flocq 3.X packages will be removed as soon as CompCert and VST are compatible with Flocq 4.0, but the opam packages will remain available and can be installed if needed.

  • Note on gappa for flocq3: the flocq3 version of gappa requires a working sed in the path - which might be a problem on Windows since the installer does not install one.

  • Note on QuickChick: QuickChick requires an OCaml compiler to run. The binary installers for Coq Platform do not provide OCaml, so QuickChick does not work with the binary installers for macOS, Windows and Snap. It is recommended to use the "compile from sources" method if you want to use QuickChick. An alternative method is to install OCaml by other means and have it in the PATH, but this method is not supported by the Coq Platform team. We plan to add an OCaml compiler to the binary installers in the next release.

Installers

Binary installers are provided for the 2022.04 pick of Coq 8.14 and 8.15 for macOS, Windows and Linux (snap). The macOS and Windows installers can be downloaded below. The snap package is available via the snapcraft.
