TiDB Cloud Releases

TiDB Cloud is a fully managed Database-as-a-Service (DBaaS) that brings TiDB, an open-source Hybrid Transactional and Analytical Processing (HTAP) database, to your cloud.

TiDB Cloud offers two types of releases: cloud platform releases and database kernel releases. They follow independent release cycles and are documented separately.

Cloud platform release notes

Cloud platform releases cover the TiDB Cloud console, APIs, and control plane, including new plan features, UI changes, integrations, and operational improvements across all TiDB Cloud plans.

Database kernel release notes

The database kernel is the core engine that processes your SQL queries and manages your data. Depending on your TiDB Cloud plan, your resources run on different kernels, each with its own release cadence.
