-- This version contains a modification to take into account new config options:
-- * "slow_mode_duration"
-- * "mute_anonymous"
-- These options are introduced in the Peertube livechat plugin.
--
-- The "slow_mode_duration" comes with mod_muc_slow_mode.
-- There will be a XEP proposal for this one. When done, these modifications will be submitted to the mod_muc_http_defaults maintainer.
