[Matthew Wild]

Hi folks,

We are pleased to announce the release of Prosody 13.0.5.

This is a security release for the Prosody 13.0.x stable series. It
fixes multiple security issues, some memory leaks and some smaller bugs
and changes which have been implemented since the previous release.

Full details about the security vulnerabilities can be found in our
security advisory at https://prosody.im/security/advisory_735dd9d3/

We encourage all Prosody operators on 13.0.4 or
earlier to upgrade to 13.0.5 as soon as possible, or to review the
advisory and implement appropriate mitigations.
