The most recent official comments I’ ve seen were from early Jan of 2020, where Juan mentioned targeting a release of 4.0 by mid-2020. For reference, that’s mentioned at least here:
Obviously though, we’re past that particular mark now. While I haven’t seen any more official estimates (maybe they exist?), I’d say the real answer is likely to be:
It’ll be released when it’s ready
Yes I guess . Probably they want to release the version has a fully functional software rather than rushing up and releasing something full of bugs and errors
