This change lets Miniflux use the same secure TLS configuration options when using Let's Encrypt / Autocert as when using a manually specified certificate. It raises the server’s SSL Labs score from a B to an A+ with LetsEncrypt.
The config parser logs a warning when the user uses a deprecated variable. It also ignores the value from a deprecated variable if it has already been set using the corresponding non-deprecated variable (and logs another warning).
- CLEANUP_FREQUENCY_HOURS instead of CLEANUP_FREQUENCY
- CLEANUP_ARCHIVE_READ_DAYS instead of ARCHIVE_READ_DAYS
