v0.6.0

2023-07-31

DefraDB v0.6 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 several new and powerful features, important bug fixes, and notable refactors in this release. Some highlight features include: The initial release of our LensVM based schema migration engine powered by WebAssembly (#1650), newly embedded DefraDB Playround which includes a bundled GraphQL client and schema manager, and last but not least a relation field (type_id) alias to improve the developer experience (#1609).

To get a full outline of the changes, we invite you to review the official changelog below. This release does include a Breaking Change to existing v0.5.x databases.
