Certbot 5.10.0 has just been released. The changelog for the release is:
Fixed
- Fixes a race condition in the webroot plugin where, if the webroot could be modified by a less privileged user while Certbot ran, the ownership and mode of an unintended file could be changed instead of those of the challenge directory Certbot had just created.
- Rejects invalid ARI suggested renewal windows whose end time is not after their start time.
