This is a bugfix release. The reason for the rapid release of the past two versions is down to a Debian developer reviewing the mosquitto package. This is a good opportunity to ensure that as bug free a version as possible is present in Debian. # Broker * Don't ask client for certificate when `require_certificate` is **false**. * Backout incomplete functionality that was incorrectly included in 1.3.2. Binaries will follow shortly.
