Astro 6.4 is out this week with some big news for build times.
There's also a zero-config Astro CMS, a dev toolbar plugin for batching UI notes straight into your coding agent, and dynamic OG images without the Satori boilerplate.
A new pluggable Markdown processor API lets you swap out the unified pipeline entirely, with a new Rust-based processor already shaving over a minute off site builds. The Cloudflare adapter gains a new helper for experimental advanced routing too.
A dev toolbar plugin that bridges your Astro UI and your coding agent. Click elements to attach notes with source locations, build up annotations across multiple routes, and copy the whole lot as Markdown straight into your agent.
Zero connects to your GitHub repo and reads your existing Zod schemas and Astro components directly, with no SDK, config file, or code changes required, giving editors a visual workspace with live preview, quality checks, and clean Git commits on publish.
