Patch Changes

• #​16774 8f77583 Thanks @​astrobot-houston! - Fixes markdown images with empty alt text (![](image.jpg)) 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).

• #​16776 3d10b5e Thanks @​matthewp! - Fixes HMR serving stale content when components are passed as props via getStaticPaths()

• #​16784 7453860 Thanks @​ematipico! - Improved the printing of the build time if it goes over the 60 seconds.

• #​16665 3dbbcee Thanks @​Princesseuh! - 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".

  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.

• #​16777 1754b91 Thanks @​matthewp! - Fixes HMR serving stale content for dynamically imported components through barrel files

• #​16730 068d924 Thanks @​harshagarwalnyu! - 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.

Patch Changes

• #​16771 07c8805 Thanks @​ematipico! - Fixes position prop on <Image> and <Picture> components breaking Content Security Policy (CSP).

• #​16593 50924ce Thanks @​yanthomasdev! - Improves error messages with more consistent and correct writing.

• #​16757 5d661cd Thanks @​astrobot-houston! - Fixes dev server serving stale content when SSR-only modules change (e.g. .astro files outside the project root in a monorepo, or dynamically imported components).

  Previously, the astro:hmr-reload plugin returned an empty array after detecting SSR-only module changes, which prevented Vite's updateModules from propagating the invalidation to the SSR module runner. The runner's evaluated module cache stayed stale, so subsequent requests continued returning old content.

  Now the plugin returns the SSR-only modules so Vite can process them through updateModules, which properly invalidates the module runner's cache and ensures fresh content on the next request.

Patch Changes

• #​16723 0f10bfe Thanks @​matthewp! - Adds fetchFile option to experimental.advancedRouting to customize or disable the entrypoint file

  export default defineConfig({
    experimental: {
      advancedRouting: {
        fetchFile: 'fetch.ts',
      },
    },
  });

• #​16723 0f10bfe Thanks @​matthewp! - Fixes Hono cache() middleware to follow the standard wrapper pattern

• #​16723 0f10bfe Thanks @​matthewp! - Adds App.Providers interface for typing custom context providers on Astro and ctx

  declare namespace App {
    interface Providers {
      oauth: import('./lib/oauth').OAuthSession;
    }
  }

• #​16723 0f10bfe Thanks @​matthewp! - Adds FetchState.response property, set automatically after pages() or middleware() completes

  const response = await middleware(state, (s) => pages(s));
  console.log(state.response === response); // true

• #​16723 0f10bfe Thanks @​matthewp! - Adds Fetchable type export for typing the advanced routing entrypoint

  import type { Fetchable } from 'astro';
  
  export default {
    async fetch(request) {
      return new Response('ok');
    },
  } satisfies Fetchable;

• #​16572 4a5a077 Thanks @​DORI2001! - Suppresses [WARN] Vite warning: unused imports from "@​astrojs/internal-helpers/remote" during prerender builds. The package is now bundled alongside astro in the prerender environment, matching how it is handled in the SSR environment.

• #​16756 b6ee23d Thanks @​astrobot-houston! - Fixes styles from Markdoc/MDX custom components not being extracted to <head> in the dev server when using the Cloudflare adapter with prerenderEnvironment: 'node' and rendering content through a wrapper component.

• #​16747 904d19a Thanks @​astrobot-houston! - Fixes Astro action requests failing in astro dev when using the Cloudflare adapter with prerenderEnvironment: 'node' alongside a prerendered catch-all route such as [...page].astro.

  Actions and other SSR POST endpoints now continue to work in dev instead of returning an HTTP 500 error.

• #​16701 3495ce4 Thanks @​demaisj! - Fix Map and Set instances saved in a content collection being broken when retrieving entries.

• #​16614 fca1c32 Thanks @​Eptagone! - Fixes entry.data type inference when a live collection is configured without a schema.

• #​16661 03b8f7f Thanks @​ocavue! - Updates typescript to v6. No changes are needed from users.

• #​16681 c22770a Thanks @​dotnetCarpenter! - Fixes an issue where SVG images with width="0" or height="0" incorrectly threw a NoImageMetadata error instead of being treated as valid dimensions.
