All frontends are websocket aware now, and ``type:websocket`` parameter became optional. It's required if support for ``websocket-path-list`` or ``websocket-transparent`` is required.
Experimental QuicTLS
~~~~~~~~~~~~~~~~~~~~
`QuicTLS <https://github.com/quictls/openssl>`_ can be used instead of classic OpenSSL on given node by using parameter ``-frontend-i-experimental-haproxy-flavour`` and setting it to ``quic``. This allows to test out if there are any issues with QuicTLS are with normal usage.
Experimental QUIC
~~~~~~~~~~~~~~~~~
QUIC with HTTP3 is available as experimental feature. It has to be enabled on each node separately by using ``-frontend-i-experimental-haproxy-quic``. Then given node will reply with proper headers on HTTPS to advertise QUIC. Please note that ``-frontend-i-experimental-haproxy-flavour`` has to be set to ``quic`` on this node too.
Note that then all frontends will be served with QUIC advertised on such node, so it's important to run such experiments very carefully, for example on same zone/region with DNS.
