Release Notes Published

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 and Hypothetical-Set Aggregate
  • 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.
