Where can I find real-time status on nightly build failures?

The #nightly-testing channel on the Leanprover Zulip chat provides up-to-date status on builds, failures, and ongoing adaptation work.

How do I find the latest stable nightly build for Mathlib?

You should check the 'nightly-with-mathlib' branch, which points to the most recent Lean nightly build that has successfully passed the Mathlib CI suite.

What is a lean-pr-testing-NNNN branch?

These branches are automatically created in the nightly-testing fork to test specific Lean PRs against Mathlib before they are merged into Lean master.

What is the purpose of the mathlib4-nightly-testing fork?

It is a separate fork used to keep experimental toolchain branches and nightly CI runs away from the main Mathlib repository, preventing pollution of the primary development history.
