== Announcements ==

    * Sponsor 28 (RACE) next meeting will be on June 27th 1800 UTC at #tor-meeting

== Discussion ==

    * do we want to move to gitlab for snowflake? (try only with one component for now) --> we are going to wait until the issue of "guests filling tickets in gitlab" is resolved.
        * gaba created https://dip.torproject.org/anti-censorship/pluggable-transports/snowflake/boards

    * Let's test our obfs4 setup guide by asking people on tor-relays@ to set up new obfs4 bridges?
    * WebSocket in Snowflake: next steps. (ahf)

    * trac management: can we 'own' tickets only when we are working on them? if you are interested in a ticket then add yourself to cc.
    * is #23888 going to be able to happen on time? do we need to take it?
