This release contains new features and bug fixes since the 2.9.3 release.
We deem it moderate priority for upgrading.

This release includes these noteworthy features:

  • Joins in continuous aggregates
  • Re-architecture of how compression works: ~2x improvement on INSERT rate into compressed chunks.
  • Full PostgreSQL 15 support for all existing features. Support for the newly introduced MERGE command on hypertables will be introduced on a follow-up release.

PostgreSQL 12 deprecation announcement
We will continue supporting PostgreSQL 12 until July 2023. Sooner to that time, we will announce the specific version of TimescaleDB in which PostgreSQL 12 support will not be included going forward.

Old format of Continuous Aggregates deprecation announcement
TimescaleDB 2.7 introduced a new format for continuous aggregates that improves performance.
All instances with Continuous Aggregates using the old format should migrate to the new format by July 2023, when support for the old format will be removed.
Sooner to that time, we will announce the specific version of TimescaleDB in which support for this feature will not be included going forward.
