# Release Notes: Time Series Analytics

## Version 2026.1

**June, 2026**
This release introduces new deployment flexibility features, a UDF management API, security
fixes, and a modernized base image for Time Series Analytics.

**New**

- Added optional CPU core-pinning support via the `CORE_PINNING` environment variable, allowing the service to prefer specific core types (E-cores, P-cores, or low-power cores).
- Added a `/udfs/package` API endpoint to upload and extract UDF deployment packages as tar archives via HTTP, enabling UDF updates without manual file placement.

**Improved**

- Changed the base Docker image from the Kapacitor image to a Debian-based Python slim image with Kapacitor installed via `.deb`, reducing image size and improving flexibility.
- Updated Intel GPU drivers to support WCL (compute-runtime/IGC version `26.14.37833`).
- Updated Kapacitor version and Python library dependency versions.
