Starlight 0.39 reworked how documentation sidebars build themselves, two point releases landed on the 6.x line, and the wider ecosystem kept moving. Here is what stood out.
What changed in Starlight 0.39?
Starlight 0.39 ships more flexible autogenerated sidebar links and stronger multilingual support. For a documentation site that lets Starlight derive its navigation from the file tree, this is the release to read.
The autogenerated sidebar is the fast path: point Starlight at a content directory and it builds the link tree. The 0.39 work loosens that, so the generated structure bends to how the docs are organized instead of mirroring the folders one-to-one.
The multilingual side gets a lift too. Docs shipped in several languages tend to fight their tooling over fallbacks and per-locale navigation, and this release smooths that for writers and readers.
The point releases
Two releases landed on the 6.x line this month. Astro 6.3 covered advanced routing; Astro 6.4 followed with build and content work, including helpers for the @astrojs/cloudflare adapter used by teams that deploy to Cloudflare Workers.
The wider ecosystem
The month also brought a spread of new integrations across image delivery, email, currency data, chat widgets, and content management, including options aimed at Astro on Cloudflare. The 6.x line reads as a stepping stone toward Astro 7. For where these releases sit together, the Astro 6 overview is a good next stop, and the Astro topic hub collects the rest. The June roundup follows next month.
