This automated release-watch entry was generated from the project's official GitHub release feed and is kept separate from human-reviewed editorial analysis. Release notes: what changed bumps catalog zod version which bumps zod in the extension, ts sdk, cli, and eve integration Summary by cubic Bumps zod to 4.6.6 across the monorepo via the pnpm catalog, upgrading the TS SDK, extension, CLI, integrations, and eve. This also makes the generated V4 protocol schema compatible with the new zod version. Unpins zod in the CLI and middleware packages in favor of the catalog: reference. Adjusts protocol schema generation so metadata ids are no longer extracted into $defs ; the standalone default extract schema now uses a fresh registry. Regenerated stagehand.v4.json emits two union types as type arrays instead of anyOf blocks. Updates the scoped release test to expect the middleware package in the release scope. Written for commit 6e1420c . Summary will update on new commits.
