[Astro 2.0: The Next-Gen 'Islands'-Oriented Web Framework](https://astro.build/blog/astro-2/) — 2.0 includes hybrid rendering (mixing of SSR and SSG outputs), type safety for Markdown & MDX, and an upgrade to [Vite 4.0](https://vitejs.dev/blog/announcing-vite4.html). Astro is worth exploring when performance is key as it works with popular frameworks but lets you deliver the least JS possible to get pages rendered.
