Updatify / Astro | Release notes

Patch Changes

• #17399 4b03702 Thanks @matthewp! - Fixes encoded request paths being routed incorrectly when using domain-based i18n

Minor Changes

• #17302 5f4dc03 Thanks @astrobot-houston! - Adds a new deferRender option to the glob() content loader

  When set to true, renderable entries (such as Markdown) are not rendered during content sync. Instead, rendering is deferred until the entry is actually rendered in a page, using the same on-demand path that .mdx files already use.

  This reduces memory usage during astro build for large collections whose rendered output is much larger than the source — for example, Markdown that uses heavy rehype plugins like rehype-katex. Such builds could previously run out of memory while storing the eagerly-rendered HTML for every entry.

  // src/content.config.ts
  import { defineCollection } from 'astro:content';
  import { glob } from 'astro/loaders';
  
  const docs = defineCollection({
    loader: glob({ pattern: '**/*.md', base: 'src/content/docs', deferRender: true }),
  });

  By default deferRender is false, preserving the existing behavior of rendering entries eagerly during sync so their rendered HTML can be cached across builds.

Patch Changes

• #17370 3a43cf0 Thanks @matthewp! - Improves internal ISR route handling

Patch Changes

• #17286 a249317 Thanks @astrobot-houston! - Fixes the first browser visit after astro dev starts triggering an immediate full page reload

• #17369 a94d4a5 Thanks @adamchal! - Fixes an issue where a client island could permanently fail to hydrate if the first attempt to load its component failed. Islands now reliably recover from transient import failures, which previously did not work for React components during astro dev.

Patch Changes

• #17368 ee74c28 Thanks @matthewp! - Fixes the generated Netlify Image CDN remote_images patterns so that regex metacharacters (such as .) in image.remotePatterns (hostname, pathname) and image.domains are matched literally instead of behaving like wildcards. This makes the generated patterns consistent with how Astro matches these values elsewhere.

Patch Changes

• #17363 3f4efc5 Thanks @astrobot-houston! - Fixes astro preview --open not opening a browser when using an adapter with a custom preview entrypoint, such as @astrojs/cloudflare

• #17313 e2e319d Thanks @ronits2407! - Exposes the AstroRuntimeLogger interface to allow users to properly type the logger functions at runtime.

• #17328 025cc74 Thanks @matthewp! - Fixes astro dev --force not replacing an already-running dev server

• #17353 2bba277 Thanks @ematipico! - Updates the Astro compiler to the latest version, which fixes many regressions. Refer to the changelog for more details.

Patch Changes

• #17345 5196fb4 Thanks @kkhys! - Fixes an opaque Cannot read properties of undefined (reading 'fileExists') crash when astro check runs against the TypeScript 7 native compiler. The native compiler does not ship the programmatic API the checker relies on yet, so astro check now fails early with a clear message pointing to the tracking issue instead.

Patch Changes

• #17318 23a4120 Thanks @astrobot-houston! - Fixes CSS module scoped-name hash mismatch in astro dev when using vite.css.transformer: 'lightningcss' with content collections. Previously, a component importing a CSS module and rendered via content collection render() would get different class name hashes in the element and the injected <style> tag, causing styles not to apply.

• #17323 4298883 Thanks @ematipico! - Fixes a dev server memory leak which caused Node.js to emit warnings in the console.

• #17323 4298883 Thanks @ematipico! - Fixes a dev server crash when a .html or /index.html suffixed request (such as those netlify dev probes as pretty-URL fallbacks) matched a dynamic endpoint route, causing a TypeError: Missing parameter error

Patch Changes

• #17323 4298883 Thanks @ematipico! - Fixes build-time image optimization ignoring a custom image service registered by an integration

  Previously, when using imageService: 'compile' or imageService: 'custom', a custom image service was only respected if it was set directly in the image.service option of astro.config. If an integration registered the service instead, images were silently optimized with the default Sharp service at build time. A custom image service now transforms your images at build time no matter how it was configured.

• #17323 4298883 Thanks @ematipico! - Prebundles astro/components and the <ClientRouter /> transition runtime modules in the dev server environment so pages using them no longer trigger a mid-session dep optimizer reload, which caused React “Invalid hook call” errors in islands on the first request after a cold cache

Patch Changes

• #17323 4298883 Thanks @ematipico! - Refactors internal WSL detection by removing the is-wsl dependency.

• #17323 4298883 Thanks @ematipico! - Replaced which-pm-runs dependency with package-manager-detector

Patch Changes

• #17059 60cb289 Thanks @dupontcyborg! - Update volar-service-* dependencies from 0.0.70 to 0.0.71 to pull in yaml-language-server 1.23.0 and yaml 2.8.3, resolving CVE-2026-33532 (GHSA-48c2-rrv3-qjmp), a denial-of-service vulnerability in yaml <2.8.3.

Patch Changes

• #17270 0142964 Thanks @FrancoKaddour! - Fix @astrojs/solid-js incorrectly claiming Svelte 5 components compiled with the newer $$renderer prop (instead of the legacy $$payload). Projects mixing Solid and Svelte could see Svelte components silently rendered as empty strings by the Solid renderer.

Patch Changes

• #17252 eb6f97e Thanks @matthewp! - Fixes trailing-slash handling for request paths that begin with a backslash

  With trailingSlash: 'always', the standalone Node server could append a trailing slash to a request path that begins with a backslash (for example /\example.com/foo) and echo that path back in the Location header of a 301 response. Because browsers resolve a leading \ the same way as /, the resulting Location could point off-site.

  Such paths are now recognized as internal paths, matching the existing handling for paths that begin with //, so they are no longer rewritten with a trailing slash.

Patch Changes

• #17259 ed6bea5 Thanks @astrobot-houston! - Fixes proxy support by respecting HTTP_PROXY and HTTPS_PROXY environment variables when downloading templates. On Node.js v22.21.0+ and v24.5.0+, create-astro now automatically enables the --use-env-proxy flag so that native fetch() routes requests through the configured proxy.

Patch Changes

• #17269 c72d4f2 Thanks @matthewp! - Fixes “Go To References” from .ts files missing usages inside .astro files that are reached through Astro.locals. The plugin now injects Astro’s ambient types so type chains like Astro.locals.utils.toUpper() resolve, matching the language server.

Patch Changes

• #17261 79aa99c Thanks @astrobot-houston! - Fixes a false deprecation warning for markdown.gfm and markdown.smartypants when using the Container API

• #17247 f94280d Thanks @chatman-media! - Fixes route generation throwing “Missing parameter” (or silently dropping the segment) when a dynamic param’s value is 0. The generator used truthy checks instead of checking for undefined, so paginate(posts, { params: { categoryId: 0 } }) would crash even though 0 is a perfectly valid param value.

• #17278 6f11739 Thanks @astrobot-houston! - Fixes missing CSS for virtual style modules (e.g., responsive image layout styles) in dev mode when JavaScript is disabled

Patch Changes

• #17242 9c05ba4 Thanks @matthewp! - Fixes an error that could occur after the dev server restarts when using an adapter such as @astrojs/cloudflare, where a request would fail with a 500 referencing a missing pre-bundled dependency:

  The file does not exist at "node_modules/.vite/deps_ssr/astro_compiler-runtime.js?v=6419660d" which is in the optimize deps directory. The dependency might be incompatible with the dep optimizer. Try adding it to `optimizeDeps.exclude`.

• #17202 c6d254d Thanks @matthewp! - Refactors path alias resolution to use Vite’s native tsconfigPaths option

  This is an internal change with no expected impact on user projects. Astro now defers tsconfig and jsconfig paths alias resolution to Vite, keeping a small fallback for a few CSS cases Vite does not yet handle.

Minor Changes

• #17099 fdab7ce Thanks @adamchal! - Adds configured image service support with the compile and custom options.

  The Cloudflare adapter supports various options that affect how images are processed for both pre-rendered and on-demand routes:

  • Setting imageService: 'compile' now ensures it is used for pre-rendered routes. When no custom image service is defined, the behavior remains unchanged.
  • With imageService: 'custom', assets are now processed at build time for pre-rendered routes. If you have configured an image service, it will be bundled to handle images at runtime; otherwise, the behavior remains unchanged.
  • The other imageService options remain unchanged.

  Learn more about the image service options available in the Cloudflare adapter guide.

Patch Changes

• #17236 c411200 Thanks @matthewp! - Prevents warnings in the Cloudflare adapter about optimizing the @astrojs/cloudflare/entrypoints/server module in dev.

Patch Changes

• #17249 02b73b0 Thanks @ematipico! - Fixes an issue where the peerDependencies field used incorrect dependencies.

Minor Changes

• #17245 f56d9e7 Thanks @astrobot-houston! - Adds edgeFunctions to the devFeatures adapter option, allowing users to disable Netlify Edge Function emulation during astro dev

  Some npm packages that access the filesystem at initialization (e.g. node-html-parser) fail inside the edge function sandbox with “Reading or writing files with Edge Functions is not supported yet.” You can now disable edge function emulation to avoid this error:

  import netlify from '@astrojs/netlify';
  import { defineConfig } from 'astro/config';
  
  export default defineConfig({
    adapter: netlify({
      devFeatures: {
        edgeFunctions: false,
      },
    }),
  });

  Edge functions will still work in production builds and via netlify dev.

• Updated dependencies []:

  • @astrojs/underscore-redirects@1.0.3

Patch Changes

• #17049 ffceaa2 Thanks @astrobot-houston! - Fixes prerender errors being silently swallowed when pages throw during rendering in workerd, causing astro build to exit 0 and emit truncated HTML. The response body is now fully buffered inside workerd before being sent back to the build process, so streaming errors are caught and surfaced as build failures with clear error messages.

• Updated dependencies []:

  • @astrojs/underscore-redirects@1.0.3

Patch Changes

• #17205 e37dfe2 Thanks @astrobot-houston! - Fixes dependency installation when creating Astro projects with pnpm 11+

Patch Changes

• #17209 fbcfa03 Thanks @matthewp! - Hardens RSS feed generation by escaping the source and enclosure item fields. These fields are now serialized as structured XML values, ensuring that special characters in values like source.title and enclosure.type are always treated as text rather than markup, consistent with how other feed fields are handled.

Patch Changes

• #17212 7ba0bb1 Thanks @matthewp! - Ensures transition directive values are HTML-escaped when rendered on hydrated islands

• #17224 dc5e52f Thanks @astrobot-houston! - Fixes trailing slash handling for dynamic file endpoints in dev mode. Dynamic file endpoints (e.g., src/pages/api/[name].json.ts) with trailingSlash: "always" incorrectly required a trailing slash in dev mode, returning 404 for /api/bar.json and 200 for /api/bar.json/.

• #17067 23f9446 Thanks @fkatsuhiro! - Fixed a bug where the development toolbar did not output a warning even though the implicit ARIA role and the manually specified role were duplicated.

Patch Changes

• #17188 675d11d Thanks @astrobot-houston! - Fixes @astrojs/upgrade showing a generic error when pnpm’s minimumReleaseAge policy blocks installation. The error message now explains that pnpm’s policy blocked the update and suggests running the install command manually.

Patch Changes

• #17142 973ea49 Thanks @astrobot-houston! - Fixes a crash when rendering shiki-highlighted code blocks inside list items

Patch Changes

• #17189 24d2c9e Thanks @astrobot-houston! - Fixes a bug where an error thrown inside one route’s getStaticPaths() would prevent other valid routes from being matched in dev mode

• #16932 8f4a3db Thanks @fkatsuhiro! - Fixes HMR for action files during development. Editing files in src/actions/ now takes effect on the next request without requiring a dev server restart.

• #17087 fb0ab02 Thanks @jp-knj! - Fixes localized custom error pages in i18n projects so routes like /pt/404 are used for missing localized pages and return the correct status code

Minor Changes

• #17185 d64b09b Thanks @delucis! - Adds a --no-ai flag to allow users to opt out of creating AGENTS.md and CLAUDE.md files when running create astro
