#Framework

The May 22 Nitro v3 beta ships build-time route handler tracing, a VFS-backed dynamic code cache for faster dev-server restarts, and Vercel queue support accessible in local development — alongside the security patches from the prior beta.

Astro 6.1.8 fixes a regression where build output filenames containing special characters caused deploy failures on Netlify and Vercel, and patches a content-type confusion vulnerability in the built-in image endpoint that could serve non-SVG content as SVG.

The April 2026 Nitro v3 beta update brings experimental tracing channels, full-trace dependency detection with native package awareness, Vercel queue support, and Tencent EdgeOne Pages deployment — alongside H3 v2 security and cookie improvements.

Svelte's March update brings createContext for programmatic component instantiation, HTML comments inside tags, SSR error boundaries, and navigation callbacks with scroll position data.

Astro 6.0 and 6.1 land within weeks of each other, bringing an experimental Rust compiler, request-time content collections, a built-in Fonts API, CSP tooling, and deeper Cloudflare integration — all while the framework doubles its adoption for the third year running.
