Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
We are switching to a new system for preparing release notes. * Release notes will be compiled when creating a release candidate from all the commits that are part of that release. * PRs can include suggestions for release notes in PR messages. Please use language such as "release notes" and "breaking changes" to call attention to the suggestions. Release notes are user-centric rather than developer-centric. * For more complicated release notes, these can be put into the `releases_drafts` folder. This solves an issue where PRs that include release notes can, when merged, have those notes appear under the wrong Lean version, since they might have been created before a release but not merged until after. It also solves merge conflicts due to multiple PRs updating the release notes. |
