Lake uses the first characters of the Lean commit hash in its version number. When this accidentally is an all-numeric string starting with a 0, some tools expecting SemVer break. We encountered that issue on v4.21.0-rc1. This empty commit rerolls the dice on the commit hash, so we hopefully do not start with a 0 or have some non-numeric characters.
This is the repository for Lean 4.
