I have noticed that Brave Dev is not linked on brave.com in any way. Is brave dev still actively maintained, or is its role taken over by the Nightly and Beta builds?
It’s “merged” to Beta. They shortened the cycle to Nightly -> Beta -> Release. Existing Dev users still get an update, but it’ll have the same version as Beta. https://github.com/brave/brave-browser/wiki/Brave-Release-Schedule
