Thanks to everyone who has tested both release candidates and given their comments and votes.
The tally is as follows: 3 binding +1s (Aman, Julian, Michael), 1 non-binding +1 (Enrico), no 0s or -1s. Therefore I am delighted to announce that the proposal to release Apache Calcite 1.15.0 has passed. I have logged https://issues.apache.org/jira/browse/CALCITE-2085 for the PsTableFunction problem noted by Enrico. Thanks everyone. I’ll now roll the release out to the mirrors, for an official announcement on Monday. Julian
