SingleStore Software End of Life (EOL) Policy

The SingleStore Helios service is continually updated to ensure that customers receive the latest features and functionality. Customers may select the time at which updates run to ensure that they do not conflict with active workloads. Refer to SingleStore Helios Scheduled Updates for more information.

From time to time, features and integrations may be deprecated, at which time notifications will be sent to discontinue use, or to move to an updated component. Customers have up to twelve (12) months to migrate off of the deprecated component before it ceases to function or the component is automatically updated.

Refer to Support Terms and Conditions for more information.
