Version Packages (beta) #696

vercel-release-bot · 2025-12-28T13:08:57Z

This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

⚠️⚠️⚠️⚠️⚠️⚠️

main is currently in pre mode so this branch has prereleases rather than normal releases. If you want to exit prereleases, run changeset pre exit on main.
