Certbot 0.38.0 was just released. The changelog entry for this version is:
Changed
- If Certbot fails to rollback your server configuration, the error message
links to the Let’s Encrypt forum. Change the link to the Help category now
that the Server category has been closed. - Replace platform.linux_distribution with distro.linux_distribution as a step
towards Python 3.8 support in Certbot.
Fixed
- Fixed OS detection in the Apache plugin on Scientific Linux.
