Apologies for leaving this unanswered for so long.

We have been working on a larger update for the live version for 26.2, and once that is in a stable state that we're happy with, we will be working in our multiloader and multiversion infrastructure. Might be another month but 1.21.1 will get the attention it needs, just not yet.

And thank you for the report.

does this mean the new features like coloured lighting released on 26.2 will eventually get backported to 1.21.1 and such?
was curious so i figured id ask here since it was mentioned (ik its unrelated, sorry)

yes, likely by the end of the month. Targets are Latest, 26.1, and 1.21.1 (Latest and previous 2 major modding versions)
