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.

What is Scalar?

Scalar's mock server learns event-driven APIs while the reference UI picks up localization

Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.

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.

Scalar's mock server learns event-driven APIs while the reference UI picks up localization

◆ Current state

Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.

◆ Where it's heading

AsyncAPI is the clear investment across all three packages — rendered in the reference, filterable in navigation, and now mockable as live event streams. The client and reference lines otherwise trend toward extension points and polish rather than new surface.

◆ Prediction

Expect AsyncAPI support to complete the loop by reaching the API client, so event-driven APIs can be exercised interactively the way REST endpoints already are.
