v0.17.1

Release date: September 17, 2025

If you are using v0.17.0, we recommend upgrading to v0.17.1.

v0.17.1 improves overall reliability and includes important bug fixes, addressing critical issues such as SST metadata truncation that could lead to process panics, deadlocks during OpenTelemetry ingestion, and correcting SubqueryAlias pushdown to resolve subquery alias performance issues.
