The Netlify team has released version 4.0 of the Astro adapter for Astro framework, which improves Server-Side Rendering (SSR), HTML streaming, access to request context, fine-grained cache control, and image CDN integration, making it easier to create highly-performant and dynamic sites. The new adapter simplifies its implementation, reduces bugs, and provides a better user experience with features like HTML streaming, automatic image resizing, and caching improvements. The team is working closely with the Astro maintainers to ensure a smooth migration process and looks forward to continuing their collaboration in the future.
