ejabberd 17.08

Happy summer with ejabberd 17.08 ! This release includes great improvements and new features. It also includes fixes and closes the biggest milestone about refactor we’ve made last couple of months. If you have issues with 17.04 or troubles using PEP, upgrade to 17.08 will fix most known issues.

New features

Introduce ‘hosts’ option

The option can be used as a replacement of ‘host’ option when several (sub)domains are needed to be registered for the module.
Note that you cannot combine both ‘host’ and ‘hosts’ in the config because ‘host’ option is of a higher priority. Example:

mod_pubsub:
   ...
   hosts:
     - "pubsub1.@HOST@"
     - "pubsub2.@HOST@"

XEP-0357: Push Notifications

This module tries to keep pending stream management sessions of push clients alive (as long as the disconnected clients are reachable via push notifications).

Modular cluster

For configuring the cluster new global option ‘cluster_backend’ is introduced. The default and only available value at the moment is ‘mnesia’.

Use c2s ‘certfile’ option

Use the ‘certfile’ listener option rather than a ‘domain_certfile’ for ejabberd_c2s listeners that have “tls: true” configured. A ‘domain_certfile’ should only be preferred for STARTTLS connections.

New mod_muc hooks

There are four new events: create_room, destroy_room, join_room and leave_room.
Note: destroy_room was previously used already by mod_mam and was named remove_room. remove_room is not renamed back to destroy_room for consistency.
