Release Highlights

• Adds support for accepting DNS connections over QUIC (doq).
• Adds CNAME target rewrites to the rewrite plugin.
• Plus many bug fixes, and some security improvements.

This release introduces the following backward incompatible changes:

• In the kubernetes plugin, we have dropped support for watching Endpoint and Endpointslice v1beta, since all supported K8s versions now use Endpointslice.
• The bufsize plugin changed its default size limit value to 1232
• Some changes to forward plugin metrics.
