 # Getting Started
 
 ::: warning
-VuePress v2 is currently in `beta` stage. It's ready to be used for building your site, but the config and API are not stable enough, which is likely to have breaking changes between minor releases. So make sure to read the [changelog](https://github.com/vuepress/vuepress-next/blob/main/CHANGELOG.md) carefully each time you upgrade a beta version.
