Does IOHK still use Daedalus Flight for pre-releases?

I wanted to get a Daedalus version with a newer cardano-node etc. as early as possible, so I found Daedalus Flight.

But when looking at the last releases, they were always at the exact same day as the regular mainnet releases of the same version, no “pre-”release there. Does anyone know if IOHK plans to resume using that stream for earlier releases, again?

Is there another (semi-)supported way to get early versions of Daedalus?
Or get just the frontend and connect it to a self-installed cardano-node and cardano-wallet?
