Why pnpm?

Beyond its speed, pnpm saves disk space by reusing packages, thereby making it an efficient alternative to npm or yarn.

New Image Optimization Techniques

Astro 3.0 takes image optimization to the next level. You can now import images directly and let Astro do the heavy lifting. For instance:

import { Image } from "astro:assets";
import myImage from "../assets/penguin.png";

<Image src={myImage} alt="A dapper penguin!" />

Astro 3.0 has migrated to Sharp, an image optimization library, and it also supports remote image optimization, making life easier for content teams.
