The Apache Calcite PMC is pleased to announce Apache Calcite release 1.34.0.

This release comes 1 month after 1.33.0, contains contributions from 18 contributors, and resolves 34 issues.

It’s worth highlighting the introduction of QUALIFY clause ([CALCITE-5268]), which facilitates filtering the results of window functions. Among other improvements and fixes, it adds roughly 15 new functions in BigQuery library for handling dates, times, and timestamps, and provides a fix ([CALCITE-5522]) for a small breaking change in DATE_TRUNC function ([CALCITE-5447]), which was introduced accidentally in 1.33.0.
