Migration Guides when you update to each Major. The Vite team works closely with the main projects in the ecosystem to ensure the quality of new versions. We test new Vite versions before releasing them through the Migration Guide for each major will list these removals and document an upgrade path for them.

Experimental Features ​

Some features are marked as experimental when released in a stable version of Vite. Experimental features allow us to gather real-world experience to influence their final design. The goal is to let users provide feedback by testing them in production. Experimental features themselves are considered unstable, and should only be used in a controlled manner. These features may change between Minors, so users must pin their Vite version when they rely on them. We will create a GitHub discussion for each experimental feature.
