Development images may be released for bleeding edge feature additions or hotfix testing purposes. These images are usually versioned as a 0.0.0-dev-XXXXXXXXXXXXXX prereleases.

Cloud Edition

In the PowerSync dashboard, developers can configure the service version channel for each instance under the General tab in the Edit Instance dialog.

Stable

The Stable channel provides the most reliable release of the PowerSync service. It includes features that may be in the V1, Beta, or Open Alpha stages. Open Alpha features in this channel are typically mature but may still have bugs or known issues.

Beta

The Beta channel builds on the Stable channel and includes new features, fixes, or modifications to existing stable functionality that may require additional testing or validation.
