Changelog
=========

0.32.0 Beta 6
=============

This beta addresses two potential areas where zeroconf can be overwhelmed and
deny service to legitimate queriers.

* BREAKING CHANGE: Drop oversize packets before processing them (#826) @bdraco

Oversized packets can quickly overwhelm the system and deny
service to legitimate queriers. In practice this is usually
due to broken mDNS implementations rather than malicious
actors.

* BREAKING CHANGE: Guard against excessive ServiceBrowser queries from PTR records significantly lower than recommended (#824) @bdraco

We now enforce a minimum TTL for PTR records to avoid
ServiceBrowsers generating excessive queries refresh queries.
Apple uses a 15s minimum TTL, however we do not have the same
level of rate limit and safe guards so we use 1/4 of the recommended value.

0.32.0 Beta 5
