6.3.0 to 6.3.1

Log Handler Configuration

The shell log handler in app.config should be renamed from shell_log to default. Otherwise, there would be duplicate logs in the shell because of the lager removal.

CA Certificate Configuration

Providing a CA certificate file (cacertfile option) is now mandatory for s2s listeners if the use_starttls option is set to required or required_trusted. Similarly, this requirement applies when fast_tls is configured with the verify_mode option set to peer or selfsigned_peer.

Multiple owner option for MUC Light

A new configuration option allow_multiple_owners was added to MUC Light. It is disabled as default. Enabling this option allows to have multiple "admin" users, while not giving more rights to room members.
