Next.js: Image Pipeline Stability and Turbopack Deadlock Fixes
The image optimization pipeline saw a cluster of reliability fixes around AVIF support, error handling, and native library tracing, while Turbopack got two separate deadlock fixes for worker and re-export cycles. Together they point to a maintenance push on edge cases that only surface in production builds.

Good day, it's August 27th, and here's your Next.js briefing.
The dominant thread today is image optimization reliability. AVIF support was disabled and then re-enabled twice over, once for the main branch and once as a backport for the 16.3 line, after a sharp library version bump. PR 97931 walks through a genuinely thorny dependency problem: package manager age gates can…
Second theme: Turbopack deadlocks. Sokra landed two separate fixes. PR 97933 stops a hang when resolving re-exports through an import cycle, by decoupling side-effect classification from full module analysis. PR 97956 fixes a related but distinct case, production builds parking at zero percent CPU when a web worker…
A few other changes worth flagging: PR 97941 fixes a memory leak in the default cache handler where cached streams held onto request context, and PR 97689 begins the deprecation path for React 18 under the Pages Router, with warnings landing now ahead of removal in Next.js 17.
What's next: if you're pinning sharp versions or using custom install age gates, check your workspace config against PR 97931's guidance. And if you run web workers that reference themselves, the Turbopack fix in 97956 is worth…
