Vue's JSX vapor channel just shipped a breaking beta that kills CommonJS support and adds a new vue-jsx package.

The vue-jsx-vapor v3.3.0-beta.1 release [1] is the headline here, with a breaking change that drops CJS entirely. The release notes say it "Drop CJS," a move that will force any ESM-only workflows to update their build config. On the same repo, the new vue-jsx package and exposed vue-jsx/vapor entry point [1] signal a clearer path for JSX in the vapor runtime. Meanwhile, the test-utils repo saw a routine dependency bump [2], updating @vitest/coverage-v8 from 4.1.10 to 4.1.11 with no breaking changes. If you're on the vapor branch, this beta is the one to watch, but for most projects, this is a low-stakes maintenance week.
