/cc @harlan-zw can you help check this, and see where could we fix it? Thanks!

Hey @Saganic

Can you provide some details on the issue? Ideally a Stackblitz reproduction.

I've pulled down the Vitesse and ran pnpm build and it looks like the title is generated correctly.

<title>Vitesse</title>

Also, the way you're describing the issue isn't accurate, title schema remains the same within v1.1. No breaking changes were introduced afiak.

Hey @harlan-zw.

Yep, I eagerly created an issue. I think it was an issue with pnpm lock on this commit. Since @antfu update the deps on latest commit, everything appears to work. If you checkout that previous commit, it does indeed still render an empty title tag.
