This release adds major new features since the 2.6.1 release. We deem it moderate priority for upgrading. This release includes these noteworthy features: * Optimize continuous aggregate query performance and storage * The following query clauses and functions can now be used in a continuous aggregate: FILTER, DISTINCT, ORDER BY as well as [Ordered-Set Aggregate](https://www.postgresql.org/docs/current/functions-aggregate.html#FUNCTIONS-ORDEREDSET-TABLE) and [Hypothetical-Set Aggregate](https://www.postgresql.org/docs/current/functions-aggregate.html#FUNCTIONS-HYPOTHETICAL-TABLE) * Optimize now() query planning time * Improve COPY insert performance * Improve performance of UPDATE/DELETE on PG14 by excluding chunks This release also includes several bug fixes. If you are upgrading from a previous version and were using compression with a non-default collation on a segmentby-column you should recompress those hypertables. **Features** * #4045 Custom origin's support in CAGGs * #4120 Add logging for retention policy * #4158 Allow ANALYZE command on a data node directly * #4169 Add support for chunk exclusion on DELETE to PG14 * #4209 Add support for chunk exclusion on UPDATE to PG14 * #4269 Continuous Aggregates finals form * #4301 Add support for bulk inserts in COPY operator * #4311 Support non-superuser move chunk operations * #4330 Add GUC "bgw_launcher_poll_time" * #4340 Enable now() usage in plan-time chunk exclusion **Bugfixes** * #3899 Fix segfault in Continuous Aggregates * #4225 Fix TRUNCATE error as non-owner on hypertable * #4236 Fix potential wrong order of results for compressed hypertable with a non-default collation * #4249 Fix option "timescaledb.create_group_indexes" * #4251 Fix INSERT into compressed chunks with dropped columns * #4255 Fix option "timescaledb.create_group_indexes" * #4259 Fix logic bug in extension update script * #4269 Fix bad Continuous Aggregate view definition reported in #4233 * #4289 Support moving compressed chunks between data nodes * #4300 Fix refresh window cap for cagg refresh policy * #4315 Fix memory leak in scheduler * #4323 Remove printouts from signal handlers * #4342 Fix move chunk cleanup logic * #4349 Fix crashes in functions using AlterTableInternal * #4358 Fix crash and other issues in telemetry reporter **Thanks** * @abrownsword for reporting a bug in the telemetry reporter and testing the fix * @jsoref for fixing various misspellings in code, comments and documentation * @yalon for reporting an error with ALTER TABLE RENAME on distributed hypertables * @zhuizhuhaomeng for reporting and fixing a memory leak in our scheduler
