Release 2.22.1

[timescale-automation]

2.22.1 (2025-09-30)

This release contains performance improvements and bug fixes since the 2.22.0 release. We recommend that you upgrade at the next available opportunity.

This release blocks the ability to leverage concurrent refresh policies in hierarchical continous aggregates, as potential deadlocks can occur. If you have concurrent refresh policies in hierarchical continous aggregates, please disable the jobs, as following:

SELECT alter_job("<job_id_of_concurrent_policy>", scheduled => false);

• #8550 Error in gapfill with expressions over aggregates and groupby columns and out-of-order columns
• #8593 Error on change of invalidation method for continuous aggregate
• #8599 Fix attnum mismatch bug in chunk constraint checks
• #8607 Fix interrupted continous aggregate refresh materialization phase leaving behind pending materialization ranges
