Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
The recent change of the trace format exposed some unexpected issues with Lake's tracing handling. This aims to fix that. Lake will now perform a rebuild if the trace file is invalid/unreadable. However, it will still fall back to modification times if the trace file is missing. Also, Lake is now backwards compatible with the previous pure numeric traces (and tolerates the absence of a `log` field in the JSON trace). |
