Hi all,

As discussed in the last horizon weekly meeting[1] on 2021-06-23, I would like to announce
that the horizon team decided to make stable/queen branch as EOL. Consider this mail as
an official announcement for that. I would like to know if anyone still would like to keep this
branch to be open otherwise, I will purpose an EOL patch for this branch.

Thanks & Regards,
Vishal Manchanda
