### Official Astro integrations

All of [Astro's official server adapters](/en/guides/on-demand-rendering/#server-adapters) have also updated to a new major version to accompany the upgrade to Vite v7.0 with Vite's Environment API as the development server and production bundler.

In particular, Astro's Cloudflare adapter has undergone significant changes, and breaking changes to your existing Cloudflare setup are expected.

#### What should I do?

If you are using an Astro adapter for on-demand rendering or other platform-specific features, please check your specific adapter's changelog for upgrade guidance:

- [`@astrojs/cloudflare` CHANGELOG](https://github.com/withastro/astro/blob/next/packages/integrations/cloudflare/CHANGELOG.md)
- [`@astrojs/netlify` CHANGELOG](https://github.com/withastro/astro/blob/next/packages/integrations/netlify/CHANGELOG.md)
- [`@astrojs/node` CHANGELOG](https://github.com/withastro/astro/blob/next/packages/integrations/node/CHANGELOG.md)
- [`@astrojs/vercel` CHANGELOG](https://github.com/withastro/astro/blob/next/packages/integrations/vercel/CHANGELOG.md)

## Legacy

The following features are now considered legacy features. They should function normally but are no longer recommended and are in maintenance mode. They will see no future improvements and documentation will not be updated. These features will eventually be deprecated, and then removed entirely.
