SDK Version Compatibility
Use this SDK version compatibility table to choose the KalamDB server, pg_kalam extension, and client SDK versions that belong together for a deployment.
Compatibility Matrix
| KalamDB server | pg_kalam extension | TypeScript SDK | Dart / Flutter SDK | Rust SDK | Notes |
|---|---|---|---|---|---|
| Latest | Latest | Latest | Latest | Beta | Recommended for new applications tracking the current docs. |
| 0.4.2-rc.3 | 0.4.2-rc.3 | 0.4.2-rc.1 | 0.4.1-beta.2 | Beta source package | Recommended release-candidate pairing for 0.4.2 testing. |
| 0.4.1-beta | Not separately archived | 0.4.1-beta | 0.4.1-beta.2 | Beta source package | Use for older beta applications that are not ready to move to 0.4.2 release candidates. |
Selection Guidance
- For new apps, start with the latest server docs and latest SDK docs unless you are pinned to a specific release candidate.
- Keep the server, pg_kalam extension, and SDKs on the same row when you need repeatable staging or production builds.
- When upgrading one component across rows, run a SQL request, an authenticated request, and a realtime subscription smoke test before rolling forward.
