Bumps astro from 5.18.2 to 6.4.3.

Release notes

Sourced from astro's releases.

astro@6.4.3

Patch Changes

• #16900 17a0fbd Thanks @​ocavue! - Bumps devalue dependency to v5.8.1

• #16016 0d85e1b Thanks @​felmonon! - Fix a false positive in the dev toolbar accessibility audit for anchors with text inside closed <details> elements.

• #16911 79c6c46 Thanks @​astrobot-houston! - Fixes a bug where experimental.advancedRouting with astro/hono handlers threw TypeError: Cannot read properties of undefined (reading 'route') for unmatched routes instead of rendering the custom 404 page.

• #16899 239c469 Thanks @​matthewp! - Fixes a false "does not call the middleware() handler" warning when using astro() in a custom src/app.ts and the first request is a redirect route.

• #16887 493acdb Thanks @​astrobot-houston! - Fixes redirectToDefaultLocale not working after the Advanced Routing refactoring.

• #16908 ef53ab9 Thanks @​florian-lefebvre! - Improves optimized fallbacks generation when using the Fonts API by using better metrics for bold variants

astro@6.4.2

Patch Changes

• #16889 b94bcfd Thanks @​Princesseuh! - Fixes a plugins is not iterable crash when using a pre-6.0 @astrojs/mdx alongside integrations (e.g. Starlight) that set markdown.remarkPlugins, markdown.rehypePlugins, or markdown.remarkRehype.

• #16878 b9f6bb9 Thanks @​fkatsuhiro! - Fixes an issue where on-demand (SSR) dynamic routes would return 404 when a prerendered dynamic route with the same URL pattern was sorted first alphabetically. In production builds with @astrojs/node adapter, if [a_prebuild].astro (prerender=true) came before [b_ssr].astro alphabetically, requests to URLs not in the prerendered route's static paths would 404 instead of falling through to the SSR route. The fix adds fallthrough logic so that when a prerendered dynamic route matches but can't serve the request, Astro tries subsequent matching routes.

astro@6.4.0

Minor Changes

• #16468 4cff3a1 Thanks @​matthewp! - Adds a new preserveBuildServerDir adapter feature

  Adapters can now set preserveBuildServerDir: true in their adapter features to keep the dist/server/ directory structure for static builds, mirroring the existing preserveBuildClientDir option. This is useful for adapters that require a consistent dist/client/ and dist/server/ layout regardless of build output type.

  setAdapter({
    name: 'my-adapter',
    adapterFeatures: {
      buildOutput,
      preserveBuildClientDir: true,
      preserveBuildServerDir: true,
    },
  });

• #16848 f732f3c Thanks @​Princesseuh! - Adds a new markdown.processor configuration option, allowing you to choose an alternative Markdown processor.

  Websites with many Markdown/MDX files tend to be slow to build because the unified ecosystem (e.g., remark, rehype) is slow to process. This feature introduces the ability to replace this part of the build pipeline with another processor.

  The default processor is unified(). This means that existing configurations remain unchanged and your remark/rehype plugins continue to work.

  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import { unified } from '@astrojs/markdown-remark';

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
