# W&B MCP Server Releases

Release notes track public source, W&B-hosted, customer-container, and
installation availability independently. Use immutable artifacts from the
version note and verify installation compatibility before upgrading. An image
publication does not by itself establish a signed source release or a qualified
installation.

| Version | Status | Release notes |
|---|---|---|
| 0.4.3 | Candidate; W&B-hosted deployed under the candidate-production exception, other channels pending | [v0.4.3](v0.4.3.md) |
| 0.4.2 | Candidate; every release channel remains pending | [v0.4.2](v0.4.2.md) |
| 0.4.1 | Public source merged; `0.4.1.1` customer image published as an image-only revision; no signed source release | [v0.4.1](v0.4.1.md) |
| 0.4.0 | Historical source note; current deployment-channel evidence is not recorded here | [v0.4.0](v0.4.0.md) |

Maintainers start new notes from [TEMPLATE.md](TEMPLATE.md) and follow the
repository [source release guide](../../RELEASING.md).
