[ANN] Prosody 0.11.3 released

[Matthew Wild]

Hi folks,

We are pleased to announce the release of Prosody 0.11.3.

This is a bugfix release for the stable 0.11 branch with quite a
number of fixes and improvements! It is recommended for all users of
0.11.x to upgrade.

An important note for those upgrading: Previous releases did not
automatically expire messages from group chat (MUC) archives, so if
mod_muc_mam was loaded and enabled for a MUC, archives would grow
indefinitely. This is not what most deployments want, therefore
automatic expiry is now implemented and enabled with a default 7 day
retention. You can configure this with the muc_log_expires_after
configuration option, which can be set to "never" to restore the old
behaviour and preserve any existing logs older than 7 days.

A summary of changes since the previous release:
