Astro [email protected] — Release Notes & Engineering Impact
Source available — automated, not human-reviewed
Component: astro · Channel: stable. Automated analysis, not a compatibility certification. How this works.
Analysis updated: 2026-11-01.
⚡ Executive Summary (TL;DR)
Astro [email protected]. Source highlight: Fixes markdown images with empty alt text (``) in content collections dropping the `alt` attribute entirely. The `alt=""` attribute is now correctly preserved in the rendered HTML output, which is important for accessibility (indicating decorative images).

🔧 Bug Fixes & Patches (6)
- Fixes markdown images with empty alt text (``) in content collections dropping the `alt` attribute entirely. The `alt=""` attribute is now correctly preserved in the rendered HTML output, which is important for accessibility (indicating decorative images).
- Fixes HMR serving stale content when components are passed as props via `getStaticPaths()`
- Improved the printing of the build time if it goes over the 60 seconds.
- Fixes remote SVG sources erroring with `dangerouslyProcessSVG` after the v6.3 SVG-processing gate. The default Sharp service now resolves the output format from the source up-front when it can (URL extension, `data:` MIME, ESM metadata), and from the actual buffer at request time when it can't, so SVG sources pass through untouched without needing to set `image.dangerouslyProcessSVG: true` or an explicit `format="svg"`.
- Fixes HMR serving stale content for dynamically imported components through barrel files
- Fixes an issue where the `file()` content loader did not generate a valid JSON Schema for collections whose JSON or YAML data is a top-level array instead of an object.

The default Sharp service now resolves the output format from the source up-front when it can (URL extension, `data:` MIME, ESM metadata), and from the actual buffer at request time when it can't, so SVG sources pass through untouched without needing to set `image.dangerouslyProcessSVG: true` or an explicit `format="svg"`.
The error message has also been updated to point at `format="svg"` as the simpler workaround when an SVG source is encountered without `dangerouslyProcessSVG` enabled.
