Thanks to everyone who has tested the release candidate and given their comments and votes.
The tally is as follows. 3 binding +1s: Julian Josh Jesús 1 non-binding +1s: Michael No 0s or -1s. Therefore I am delighted to announce that the proposal to release Apache Calcite 1.9.0 has passed. Thanks everyone. We'll now roll the release out to the mirrors. There was some feedback during voting. I shall open a separate thread to discuss. Jesús
