Good morning, it's Thursday, November 5th, 2026, and this is Next.js Daily.
The lead story today is simplification in Turbopack. Hand-written virtual modules are being replaced by normal synthetic modules that go through standard resolution and chunking.
First, dynamic module features now use the regular module pipeline. Pull request 100526 converts require context into a synthetic common module next to the caller, and pull request 100535 does the same for import meta glob as a synthetic E S module. In practice that means lazy matches use normal dynamic import…
That cleanup also improves errors. Pull request 100534 reports unknown module types at the import that pulled the file in, which matters for generated requests like globs and contexts where users never wrote the import by hand. And pull request 101161 fixes issue headers to show the source-mapped file with correct…
Second, the image optimizer public API is being narrowed before version 16 point 5. Pull requests 101133, 101126 and 101167 remove unused cache reuse and dev output handling from the transform API, putting that responsibility back on the caller. Separately, pull request 98271 fixes local image fetching to follow…
