Next.js (notes)

Is Next,js 14.2.25 LTS stable?

Next.js version 14.2.25 is generally considered stable, especially after the initial release and subsequent patch fixes. While some users reported issues with upgrades from previous versions, the core framework is stable. A security vulnerability was identified and fixed in 14.2.25, along with other versions, so updating is crucial for security reasons. Here's a more detailed breakdown:

• Stability in general: Next.js 14.2.25 is generally stable, especially after the first patch release following the initial 14.2.0 release, according to a Reddit thread.

• Security Vulnerability: A critical security vulnerability (CVE-2025-29927) was discovered in Next.js versions supporting App Router, including 14.2.x, and has been patched in 14.2.25. This vulnerability allowed for authentication bypass in middleware, and it's crucial to update to the patched version.

• Upgrading: While starting a new project with 14.2.25 is generally smooth, upgrading from previous versions (especially 13.x) can sometimes introduce issues.

• Turbopack: Turbopack, the new Rust-based bundler, is considered stable for development use (next dev --turbo) and is significantly improving local development performance.

• Production Use:Next.js 14.2.25 is suitable for production use, especially after applying the security patches.

• Future considerations: Next.js 14 is in maintenance LTS, Next.js 15 is actively being developed with new features and performance improvements.
