Update Information:
Prosody 0.11.9 ============== This release addresses a number of important
security issues that affect most deployments of Prosody. Full details are
available in a separate security advisory. Upstream recommends that all
deployments upgrade or apply the mitigations described in the advisory:
https://prosody.im/security/advisory_20210512/ Note: Upstream updated the
default config file. DNF or RPM will create a
`/etc/prosody/prosody.cfg.lua.rpmnew` file, so make sure you update your
existing `/etc/prosody/prosody.cfg.lua` to enable mod_limits after the upgrade.
