v4.0.0-rc2 Pre-release
Pre-release

This is the second release candidate for the first official release of Lean 4.

It replaces v4.0.0-rc1 as we decided that the experimental build/lake.lock behaviour was too disruptive to users, and temporarily removed it.

This is the second milestone release of Lean 4. With too many improvements and bug fixes in almost all parts of the system to list, we would like to single out major improvements to simp and other built-in tactics as well as support for a goal view that make the proving experience more comfortable.

v4.0.0-m1 Pre-release
Pre-release

The Lean development team is proud to announce the first milestone release of Lean 4. This release is aimed at experimentation with the new features of Lean 4, eventually leading to a full release of 4.0.0 ready for general use.

This release is the result of almost three years of work since the release of Lean 3.4.0, reworking, extending, and improving almost all aspects of Lean. More information about Lean 4 can be found in the official documentation as well as in the introductory talk "An overview of Lean 4" at Lean Together 2021.
