What is Fission?

Fission's release feed carries only RC tags, and none of them say what shipped

Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.

What is Payload CMS?

Payload 4.0 beta 5 is a fix release with one adapter-facing breaking change.

Payload v4.0.0-beta.5 is a short fix list: password validation on reset, hidden fields excluded from GraphQL mutation inputs, plugins able to override other plugins' options, and signed upload receipts. Its one breaking change moves extra upload fields into clientData for adapters running without receipts, which no first-party adapter does. Beta releases now ship per-package SBOMs.

Fission's release feed carries only RC tags, and none of them say what shipped

◆ Current state

Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.

◆ Where it's heading

What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.

◆ Prediction

This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.

6.3

Payload 4.0 beta 5 is a fix release with one adapter-facing breaking change.

◆ Current state

Payload v4.0.0-beta.5 is a short fix list: password validation on reset, hidden fields excluded from GraphQL mutation inputs, plugins able to override other plugins' options, and signed upload receipts. Its one breaking change moves extra upload fields into clientData for adapters running without receipts, which no first-party adapter does. Beta releases now ship per-package SBOMs.

◆ Where it's heading

The 4.0 beta lands every three to five days, and each one is smaller than the last. beta.0 shipped the admin redesign, TanStack support and the new MCP. Later betas covered adapters, Next.js cache components and accessibility, and beta.5 is mostly correctness and supply-chain hygiene, which suggests a release candidate is close.

◆ Prediction

Expect one or two more fix-only betas, then a 4.0 release candidate. The SBOM addition suggests supply-chain artifacts will carry over to stable releases.
