No edition 2024 in the combobox.

How do I play with gen blocks, which seem to require setting edition to unstable so far 2024? Even manually editing edition=2021 URL parameter does not make it force the new edition.

Maybe 2024 should be added in GUI for Nightly and custom editions (e.g. 2027) be specifiable in the URI?

I'm not a fan of unconstrained inputs. We create an edition every three years; I think that having a few days where the playground doesn't have it are an acceptable tradeoff.
