This release contains the bug fixes introduced since TimescaleDB v2.15.1. Best practice is to upgrade at the next available opportunity.

After you run ALTER EXTENSION, you must run this SQL script. For more details, see the following pull request #6797.

If you are migrating from TimescaleDB v2.15.0 or v2.15.1, no changes are required.

  • #6975: Fix sort pushdown for partially compressed chunks.

This release contains the performance improvements and bug fixes introduced since TimescaleDB v2.14.2. Best practice is to upgrade at the next available opportunity.

  • Continuous Aggregate now supports time_bucket with origin and/or offset.
  • The following improvements have been introduced for hypertable compression:
    • Recommend optimized defaults for segment by and order by when configuring compression through analysis of table configuration and statistics.
    • Added planner support to check more kinds of WHERE conditions before decompression. This reduces the number of rows that have to be decompressed.
    • You can now use minmax sparse indexes when you compress columns with btree indexes.
    • Vectorize filters in the WHERE clause that contain text equality operators and LIKE expressions.

After you run ALTER EXTENSION, you must run this SQL script. For more details, see the following pull requests #6797.

  • Ability to change compression settings on existing compressed hypertables at any time. New compression settings take effect on any new chunks that are compressed after the change.
  • Reduced locking requirements during chunk recompression
  • Limiting tuple decompression during DML operations to avoid decompressing a lot of tuples and causing storage issues (100k limit, configurable)
  • Helper functions for determining compression settings
  • Plan-time chunk exclusion for real-time Continuous Aggregate by constifying the cagg_watermark function call, leading to faster queries using real-time continuous aggregates

Following the deprecation announcement for Multi-node in TimescaleDB 2.13, Multi-node is no longer supported starting with TimescaleDB 2.14.

TimescaleDB 2.13 is the last version that includes multi-node support. Learn more about it here.

If you want to migrate from multi-node TimescaleDB to single-node TimescaleDB, read the migration documentation.

TimescaleDB 2.14 is the last version that will include the recompress_chunk procedure. Its functionality will be replaced by the compress_chunk function, which, starting on TimescaleDB 2.14, works on both uncompressed and partially compressed chunks. The compress_chunk function should be used going forward to fully compress all types of chunks or even recompress old fully compressed chunks using new compression settings (through the newly introduced recompress optional parameter).

Note

This release contains performance improvements for compressed hypertables and continuous aggregates and bug fixes since the 2.11.2 release. It is recommended that you upgrade at the next available opportunity.

This release moves all internal functions from the _timescaledb_internal schema into the _timescaledb_functions schema. This separates code from internal data objects and improves security by allowing more restrictive permissions for the code schema. If you are calling any of those internal functions you should adjust your code as soon as possible. This version also includes a compatibility layer that allows calling them in the old location but that layer will be removed in 2.14.0.

Following the deprecation announcement for PostgreSQL 12 in TimescaleDB 2.10, PostgreSQL 12 is not supported starting with TimescaleDB 2.12. Currently supported PostgreSQL major versions are 13, 14 and 15. PostgreSQL 16 support will be added with a following TimescaleDB release.

Important

This release contains new features and bug fixes since the last release. It is considered moderate priority for upgrading. Upgrade your TimescaleDB installation as soon as possible.

  • PostgreSQL 12 is now deprecated in TimescaleDB, and remains supported until July 2023. For more information about upgrading PostgreSQL, see the Upgrading PostgreSQL section.
  • The older format of continuous aggregates is now deprecated, and remains supported until July 2023. For more information about the new continuous aggregate format, see the continuous aggregates section.
