OpenUI core and React reach 1.0; other renderers retain 0.4 dependencies

npm confirms October 12 publication of lang-core and react-lang 1.0.0. Vue, Svelte and Angular 0.4.2 retain lang-core ^0.4.1.

Why it matters

Match model output formats to renderer dependencies rather than relying on the project's 1.0 headline.

A closer look

October 15 manifests for all three non-React renderers retain ^0.4.1; React 1.0.0 requires ^1.0.0. Registry manifests clarify conflicting release-page summaries.

Who this is for

Generative UI and multi-framework integration teams

Revisions & corrections (2)

— Resolved review using authoritative npm publication timestamps and version manifests: all three 0.4.2 renderers pin lang-core ^0.4.1; GitHub generated dependency summary is not the manifest. Preserve original event date and record history.

— Version-specific 1.0 release could not be read; verify package manifests and actual published dependencies before claiming cross-framework compatibility.
