v0.4.0

2023-12-23

DefraDB v0.4 is a major pre-production release. Until the stable version 1.0 is reached, the SemVer minor patch number will denote notable releases, which will give the project freedom to experiment and explore potentially breaking changes.

There are various new features in this release - some of which are breaking - and we invite you to review the official changelog below. Some highlights are persistence of replicators, DateTime scalars, TLS support, and GQL subscriptions.

This release does include a Breaking Change to existing v0.3.x databases. If you need help migrating an existing deployment, reach out at [email protected] or join our Discord at https://discord.source.network/.
