The legacy logrotate config filepath was changed from `/etc/logrotate.d/airtime-php` to `/etc/logrotate.d/libretime-legacy`. The old configuration file must be removed:
- the`general.protocol`, `general.base_url`, `general.base_port`, `general.base_dir` and `general.force_ssl` entries were replaced with a single `general.public_url` entry, be sure to use a valid url with the new configuration entry.
