topmost (closest to the root) certificate in the chain, instead of checking
every certificate in the chain.
- Support for Python 2 has been removed.

installation. In this release, we are beginning to disable updates to the
certbot-auto script itself. This release includes Amazon Linux users, and all
other systems that are not based on Debian or RHEL. We plan to make this

an apache2ctl symlink and uses apachectl instead.
- Fixed a typo in
