At the moment we are mainly waiting for CALCITE-4446 [1], CALCITE-4488 [2],
for preparing the first RC for 1.27.0.

I know that some people started testing the current master (thanks!) and it
would be great if others start doing so as soon as possible in order to
have a smooth release.
If testing with master is not feasible, testing with 1.26.0 and providing
feedback (positive or negative) can also help a lot.

Best,
Stamatis
