Projects using the Unhead Bundler with Vite 6 or 7, webpack, Rspack, Rollup, or another build without Rolldown no longer receive oxc-parser from @unhead/bundler. Builds that use Unhead transforms must install it directly.

Migration

pnpm add -D oxc-parser

Runtime-only Unhead projects and builds with Rolldown installed need no change.
