Good morning. This is Next.js Daily for April 29th, 2026.
No merged pull requests today, but developers pushed 17 commits with several important improvements.
Janka Uryga fixed a critical issue with error boundaries that failed to handle falsey values like `undefined` or `null` when thrown. The previous logic would incorrectly render children instead of error fallbacks, potentially causing infinite loops. The fix wraps thrown values in a discriminated union structure.
Tobias Koppers introduced OS-level memory pressure monitoring to TurboMalloc. The new system reports normalized memory pressure values from 0 to 100 across Linux, macOS, and Windows platforms. This data now appears in trace samples and will eventually help with task eviction decisions in turbo-tasks.
Zhang Hao added experimental support for `turbopackWorkerAssetPrefix`, addressing cross-origin Worker issues when using CDN asset prefixes. When `assetPrefix` points to a cross-origin CDN, browsers reject Worker creation with SecurityError. The new option allows developers to keep Workers same-origin while serving…
