Good morning, this is Next.js Daily for May 5th, 2026.
The team merged 14 pull requests yesterday with significant infrastructure and performance improvements.
gnoff merged a backport that includes deployment ID in cache handler keys, addressing a critical issue where development builds always used the same cache key. This fix affects 22 files across the build system and app rendering pipeline.
eps1lon led several CI modernization efforts, moving Turbopack, Rspack, and font data workflows off the deprecated RELEASE_BOT_GITHUB_TOKEN to a new GitHub app system. A separate merge migrated the React sync workflow using the same approach, enabling multiple signed commits for easier review.
unstubbable fixed a URL encoding bug in client parameter parsing that was causing double-encoding of pathname parts. The fix ensures client and server produce matching cache keys, preventing unnecessary cache invalidation and redundant prefetch requests.
Another fix from unstubbable resolved dev mode reload errors during back navigation between Next.js pages by implementing per-document debug channel storage instead of a shared key system.
