- Fixed a security vulnerability (CVE-2025-13465) in vendored lodash
- Stabilized several experimental features including instant navigation, app shells, and cache components
- Enabled Turbopack build filesystem cache and TypeScript CLI by default
- Improved performance and fixed numerous bugs across rendering, caching, and HMR systems
Several experimental features have been stabilized and enabled by default (instant navigation, app shells, cache components, Turbopack filesystem cache, TypeScript CLI), which may change behavior for applications relying on previous defaults or experimental flags. The edge runtime has been deprecated. Some configuration options like experimental.useCache are now deprecated.
Review and test applications using experimental features that are now stabilized. Check if any code relies on the edge runtime (now deprecated) or experimental.useCache (now deprecated). Verify that default behavior changes for instant navigation, app shells, and cache components work as expected in your application.
