Changelog

7.3.7
Oct 7, 2026
🐞 Patch Changes
- #18266 cba76cc Thanks @astro-factory! - Fixes a build error when a Markdown content collection entry loaded with glob({ deferRender: true }) has a layout frontmatter property. layout is now ignored for content collection entries, as documented.
- #18287 38f6793 Thanks @astro-factory! - Fixes astro add cloudflare failing to install dependencies with pnpm v11+ by approving the workerd build script, and shows the package manager’s error output when astro add fails to install dependencies
- #18222 fcf6ed6 Thanks @mingjunlu! - Fixes an issue where AVIF images were served as image/heif instead of image/avif in the dev server.
- #18240 de4df06 Thanks @astro-factory! - Fixes the cache() handler from astro/hono and astro/fetch throwing a TypeError when a cache provider is configured. It now registers the cache provider before rendering, so Astro.cache is available to downstream handlers like pages().
- #18268 547b572 Thanks @astro-factory! - Fixes security.checkOrigin rejecting cross-origin requests with non-form content types such as application/json. As documented, the check only applies to unsafe requests that have no content-type header or one of application/x-www-form-urlencoded, multipart/form-data, or text/plain.
7.3.6
Oct 6, 2026
🐞 Patch Changes
- #18166 5134d0f Thanks @astro-factory! - Fixes an intermittent dev server crash when using astro:actions inside a server island with adapters that use a pre-bundled SSR environment (e.g. @astrojs/cloudflare)
- #18076 8a2df66 Thanks @astro-factory! - Fixes stale scoped styles during HMR when both markup and <style> are changed in a single save
- #18252 2d29e7e Thanks @astro-factory! - Fixes CSS from other pages leaking into a page’s <head> in dev when the page imports a module such as astro:config/server.
- #18000 6724575 Thanks @barclayd! - Fixes a bug where server islands containing framework components rendered empty in the dev server when using a custom src/fetch.ts
- #18241 7c5fd6f Thanks @astro-factory! - Fixes the composable i18n() handler from astro/fetch and astro/hono returning an empty 404 for paths without a locale prefix. It now renders the custom 404 page, matching astro().
- #18164 1a6997f Thanks @astro-factory! - Fixes CSS Module HMR in dev when a component is rendered both with and without hydration on the same page. Astro now uses path-based class name hashing in dev mode so that editing CSS declarations no longer changes the generated selectors, allowing Vite’s CSS HMR to update styles without a full page reload.
- #18243 dd29d62 Thanks @astro-factory! - Fixes context.props being null in middleware and endpoints when the composable astro/hono or astro/fetch actions() handler runs before middleware(), or when pages() runs without middleware()
- #18193 95d5d16 Thanks @astro-factory! - Fixes astro build failing on Windows with Node.js 25+ with ERR_INVALID_ARG_VALUE when clearing the output directory hits a transient EPERM error
- #18220 d6c13a4 Thanks @astro-factory! - Fixes type errors reported in Astro’s built-in <Picture /> and <Font /> components when type-checking a project with tsc and @astrojs/ts-content-mapper
- #18133 faac481 Thanks @astro-factory! - Fixes lost request state when Vite discovers server dependencies during a request in Cloudflare dev mode
- #18146 2af4516 Thanks @astro-factory! - Fixes CSS imported from an injectScript('page') script being dropped during build
- #18159 e5f8fe0 Thanks @astro-factory! - Fixes a hang when a server:defer component is inside a slot of another component in an MDX content collection entry
- #18246 c3b42ad Thanks @astro-factory! - Fixes the glob() loader skipping content files whose paths contain # or ?
- #18248 b97184e Thanks @astro-factory! - Fixes a bug where page routes added with injectRoute() returned a 404 when i18n.routing.prefixDefaultLocale was true and the route path had no locale prefix
- #18251 3415263 Thanks @astro-factory! - Fixes content collection changes being ignored in astro dev after the dev server restarts because of a config change
- #18226 ad54af0 Thanks @imharjot! - Fixes Astro.cookies.get() returning undefined for request cookies with empty values
- #18155 37ab0e4 Thanks @astro-factory! - Fixes nondeterministic ordering of the server manifest’s assets array, ensuring builds with identical inputs produce byte-identical output
- #18099 6987261 Thanks @renovate! - Adds YAML parsing with timestamp and merge key support, and formats YAML errors consistently across Astro, Markdown, MDX, and Markdoc.
- #15595 64e4039 Thanks @qzio! - Improves CSRF protection by taking modern browsers headers into account
- #18215 941bd5e Thanks @ump45nose! - Fixes a runtime ReferenceError for inlined scripts that import a URL with /* @vite-ignore */.
  
  Astro now inlines scripts after Vite replaces its preload markers, so ignored dynamic imports can remain inline without shipping an unresolved __VITE_PRELOAD__ reference.
- #18179 6caa659 Thanks @matthewp! - Fixes custom View Transition direction names that are not valid CSS identifiers, such as names starting with a digit or containing spaces. These directions now match their animations correctly.
- #18250 7eae39b Thanks @astro-factory! - Fixes a 404 for a CSS file that a dynamic import preloads when the imported module uses a component that is also a hydrated island on the same page
- #18176 7c9d00d Thanks @astro-factory! - Fixes duplicate CSS in production builds when a component is both server-rendered and used with client:only on the same page
- #18245 492e95f Thanks @astro-factory! - Fixes the composable astro/fetch and astro/hono handlers (trailingSlash(), redirects(), actions(), middleware(), and pages()) so they reject over-encoded request paths with a 400 Bad Request, matching astro(). For these requests, redirects() and actions() return the 400 response instead of undefined, so no redirect is issued and no action runs.
- #18078 0a2ab10 Thanks @manuelgruber! - Fixes Astro.rewrite() and context.rewrite() selecting the wrong route in astro dev when two dynamic routes match the same path
- #18210 62b13ba Thanks @edmundhung! - Allows Astro CLI commands to install tagged package versions
- #18069 d39eb97 Thanks @astro-factory! - Fixes a dev server dependency scan failure when an .astro file contains a literal <script in frontmatter or a template expression
- #18114 c17d920 Thanks @matthewp! - Fixes Astro on StackBlitz and other WebContainer environments
- #18088 cb767f9 Thanks @astro-factory! - Fixes a MODULE_LEVEL_DIRECTIVE warning during build caused by a stale "use astro:head-inject" directive in content collection propagated asset modules
- #18247 2b3f73d Thanks @astro-factory! - Fixes actions returning 500 for malformed JSON request bodies and undecodable action names. A SyntaxError from invalid JSON now returns 400 (BAD_REQUEST), and a URIError from a malformed percent-encoded action name now returns 404 (NOT_FOUND).
- 1d9e910 Thanks @matthewp! - Validates the Host header against security.allowedDomains when using the Node adapter
- #18249 c7799a4 Thanks @astro-factory! - Fixes the fontsource font provider to resolve variable fonts when using the “Variable” suffix in the font name (e.g. "Inter Variable")
- #18163 e48da9d Thanks @astro-factory! - Fixes <video muted> losing its muted state after a ClientRouter navigation in Chrome
- #18244 f67e7f7 Thanks @astro-factory! - Fixes localized error pages such as src/pages/pt/404.astro returning a 200 status when rendered through the pages() handler from astro/fetch or astro/hono
- #18242 c5275e3 Thanks @astro-factory! - Fixes experimental_AstroContainer output including dev toolbar data-astro-source-file and data-astro-source-loc attributes when rendering components under Vitest

7.4.0-beta.0
Oct 1, 2026
🍿 Minor Changes
- #18112 c68d737 Thanks @jamesopstad! - Allows integrations to control where Astro writes client, server, and prerender build output.
  
  Custom prerenderers can access the final output locations through the new outputDirectories context:
  setPrerenderer((defaultPrerenderer, { outputDirectories }) => { const { client, server, prerender } = outputDirectories return createPrerenderer({ defaultPrerenderer, client, server, prerender, }) })
🐞 Patch Changes
- #18112 c68d737 Thanks @jamesopstad! - Fixes deployment integrations being unable to use Vite manifests when preparing build output

7.3.5

Sep 24, 2026

🐞 Patch Changes

#17736 2b8b2e8 Thanks @ematipico! - Adds a new container function called renderComponent(), which renders Astro components with inlined styles and scripts.

Users must import the component with the new ?container query string:

import { experimental_AstroContainer } from "astro/container";
import TodoList from "../components/TodoList.astro?container";

const container = await experimental_AstroContainer.create();

const _string = container.renderComponent(TodoList);

7.3.4
Sep 22, 2026
🐞 Patch Changes
- #18063 40896ac Thanks @adamchal! - Fixes incremental builds repeatedly rendering unchanged pages when modules or compiled CSS reference bundled assets.
- #18053 cf5d72f Thanks @Princesseuh! - Improves the astro check error shown for TypeScript 7. The command now explains that TypeScript 7 is not currently supported and provides instructions for experimentally type-checking Astro files with TypeScript 7.1 and @astrojs/ts-content-mapper.
- #18086 795a7e4 Thanks @ump45nose! - Fix double-escaped ampersands in Markdown image alt and title attributes. The __ASTRO_IMAGE_ round-trip now decodes the numeric (&) and named (&) character references the Markdown processors emit, so an & in an alt or title is escaped exactly once in the final HTML instead of twice.
- #18074 0429805 Thanks @SurefireStudios! - Fix three error names that did not match their documented reference. MissingLocale, MissingIndexForInternationalization and NoManifestAvailable reported names ending in Error in the dev overlay, while their error reference pages are published under the unsuffixed names, so the name shown to users could not be found in the docs.
- #18007 2245837 Thanks @L4XB! - Fixes the dev server re-evaluating the whole server module graph on every request. The astro:head-metadata plugin invalidated its component metadata virtual module from its own transform hook, so each evaluation of that module scheduled the next one. Adapters that run requests outside Vite’s module runner, such as @astrojs/cloudflare, paid for a full re-evaluation of the server graph on every request for the lifetime of the process.
- #18096 43657c4 Thanks @matthewp! - Fixes domain-based i18n routing to respect security.allowedDomains when selecting a locale from request host headers
- #18043 8a53a8b Thanks @astro-factory! - Fixes image.responsiveStyles emitting invalid object-position CSS values for same-axis keyword pairs (top bottom, left right, etc.)
- #18029 c08252d Thanks @matthewp! - Runs astro dev and astro preview in the foreground when an AI agent is detected on Windows, allowing the agent to manage the process lifetime. Pass --background explicitly to request an Astro-managed background process. Agent-inferred backgrounding remains enabled on other platforms.

7.3.3
Sep 16, 2026
🐞 Patch Changes
- #17651 504333c Thanks @sxzz! - Refactors internal version handling to use a smaller, ESM-native dependency
- #17942 0bc5715 Thanks @matthewp! - Returns appropriate 400 and 404 responses from the image endpoint for invalid and missing local image paths
- #17700 b2222fc Thanks @winklemad! - Fixes Astro.preferredLocaleList returning an empty list when a locale is configured with the object form ({ path, codes }) and the browser sends the code with different casing or an underscore, such as en-US matching a configured en-us
- #17941 394ff79 Thanks @matthewp! - Fixes astro preview --ignore-lock (and astro dev --ignore-lock) being refused when run from an AI agent environment. The flag now starts the server in the foreground instead of erroring, since agent detection only inferred background mode and was never explicitly requested. An explicit --background combined with --ignore-lock still errors.
- #17928 3277927 Thanks @ArmandPhilippot! - Fixes TypeScript autocompletion for getImage() to suggest all available predefined options.
- #17928 3277927 Thanks @ArmandPhilippot! - Fixes a type error in getImage() options that allowed passing both widths and densities at the same time.
- #17857 2637ed1 Thanks @Princesseuh! - Improves rendering performance
- #17943 2fc7ce9 Thanks @matthewp! - Fixes a WebAssembly error when importing astro:actions in tests that run under @cloudflare/vitest-pool-workers
- #18018 1b5a234 Thanks @astro-factory! - Fixes trailing-slash redirect response body pointing to the incoming URL instead of the redirect target. The location header was correct, but the HTML body (<meta http-equiv="refresh">, <title>, and <a> tag) contained the original request path without the trailing-slash correction or query string.
- #17905 eaf70fa Thanks @SudoDevStudio! - Fixes custom dev toolbar apps losing their UI after client-side navigation with <ClientRouter />.
- #18011 558b301 Thanks @astro-factory! - Fixes prerendered Cloudflare pages rendering as [object Object] when nodejs_compat is enabled in wrangler.toml
- #17944 ba08e35 Thanks @matthewp! - Fixes a regression in astro dev where writes outside the module graph (for example, @astrojs/cloudflare’s .wrangler/state files) invalidated the middleware on every request, causing repeated SSR reloads. Such writes no longer invalidate the middleware.
- #17531 ae837db Thanks @danilloestrela! - Updates svgo to 4.0.2 to resolve a security advisory
- #17953 dbbf10e Thanks @astro-factory! - Fixes a one-time page reload shortly after the first load on cold dev-server starts when a project has framework components imported from MDX content entries. MDX files are now included in the dev dependency pre-bundling scan, so their framework dependencies are bundled up front instead of being discovered (and reloaded for) at runtime.
- #17955 4e8ad9a Thanks @matthewp! - Improves dev server startup time. The content config and dev server app module graphs now begin compiling during server creation without blocking the server from listening. Request handling waits for the shared setup result when needed, cutting astro dev ready time by roughly a third on projects with a content config.
- #17960 9838049 Thanks @Chy-Zaber-Bin-Zahid! - Improves the diagnostics of some Astro errors.
- #17998 0e5478d Thanks @astro-factory! - Fixes SVG <style> elements nested inside <defs> or other container elements not being hashed for CSP
- #17994 80f9f1d Thanks @astro-factory! - Fixes experimental.incrementalBuild restoring pages with stale CSS after a preprocessor partial changes or missing original images referenced by restored pages
- #17889 8ae6b46 Thanks @ajfAfg! - Fixes a bug where the dev server stripped the configured base from URLs that only share a prefix with it. With base: '/s', requests to /src/... were rewritten to /rc/... and failed, breaking those pages during development.
- #17980 cfccafa Thanks @gameroman! - Improves JSDoc for fonts api
- #17953 dbbf10e Thanks @astro-factory! - Fixes CSS HMR for framework components rendered through content entries after ClientRouter navigation
- #17970 0b4dc3a Thanks @matthewp! - Improves serialization of transition animation values in generated CSS
- #17999 30ef3cb Thanks @astro-factory! - Fixes content collection HMR not updating prerendered pages when an adapter enables a separate prerender environment (e.g. @astrojs/cloudflare with prerenderEnvironment: 'node')
- #18002 312ab49 Thanks @shoutoutuoadi325! - Fixes redirect targets being corrupted when a dynamic route parameter value contains $ replacement patterns like $&
- #17937 e294953 Thanks @matthewp! - Fixes a bug where the glob() content loader kept stale entries in the data store after the last file in a collection was deleted. Empty collections are now pruned correctly, and the file watcher is registered in dev so the first file added to an empty collection is picked up without a restart.
- #17945 750b4db Thanks @matthewp! - Pre-bundles renderer server entrypoints and the default console logger during dev so they are included in the initial optimization pass, preventing a mid-request re-optimization that could crash the dev server on Cloudflare (workerd).
7.3.2
Sep 8, 2026
🐞 Patch Changes
- #17896 a548223 Thanks @matthewp! - Fixes <script>/<style> rendering in MDX so that only literal content (including content injected by remark/rehype plugins) is treated as trusted markup. A dynamic value passed as a <script>/<style> child (e.g. <script>{value}</script>) is now escaped like any other element’s content instead of being rendered raw. Use set:html to explicitly opt a dynamic value back into raw rendering.
- #17931 c1a6a89 Thanks @astro-factory! - Fixes the dev toolbar returning a 504 “Outdated Optimize Dep” error when a workspace-linked package imports a dependency that Vite’s initial scan did not discover
- #17908 42e9188 Thanks @astro-factory! - Fixes i18n fallback routing replacing the first substring match instead of the actual locale segment, which mangled paths like /energy/en/about into /esergy/en/about
- #17936 4b92ddc Thanks @astro-factory! - Fixes sessions breaking in dev mode with the Cloudflare adapter when middleware is present
- Updated dependencies [a548223]:
  - @astrojs/markdown-satteri@0.4.1
7.3.1
Sep 3, 2026
🐞 Patch Changes
- #17899 0389640 Thanks @ematipico! - Fixes an error that prevented projects using astro:assets from starting or building
7.3.0
Sep 3, 2026
🍿 Minor Changes
- #17767 ce7c91f Thanks @astro-factory! - Adds --ignore-lock flag to astro preview, allowing multiple preview servers to run simultaneously on different ports. This is useful for E2E testing workflows (e.g., Playwright) that need to run several preview servers at once.
- #17818 c0b6581 Thanks @florian-lefebvre! - Adds a logger parameter to image services hooks
  
  Custom image services now receive Astro’s runtime logger as an extra argument. Messages logged with it are routed through the destination configured in logger and respect your log level, instead of being written straight to the console:
  import type { LocalImageService } from 'astro'; const service: LocalImageService = { // ... async transform(inputBuffer, transform, imageConfig, logger) { logger.warn(`Could not optimize "${transform.src}". Passing it through unchanged.`); return { data: inputBuffer, format: 'png' }; }, };
  Astro’s built-in Sharp service now uses this logger for the warnings it emits when it encounters an unexpected or unsupported source format.
- #17818 c0b6581 Thanks @florian-lefebvre! - Adds logger to the context object passed to cache providers
  
  Custom cache providers now receive Astro’s runtime logger on the context passed to onRequest(). Messages logged with it are routed through the destination configured in logger and respect your log level, instead of being written straight to the console:
  import type { CacheProvider } from 'astro'; const provider: CacheProvider = { name: 'my-cache', async onRequest({ request, url, logger }, next) { logger.warn(`Skipping cache for ${url.pathname} because the response sets a cookie.`); return next(); }, // ... };
  Astro’s built-in memoryCache() provider now uses this logger for the warnings it emits when it skips caching a response that sets cookies, and when a background revalidation fails.
🐞 Patch Changes
- #17818 c0b6581 Thanks @florian-lefebvre! - Updates Astro’s remaining internal warnings and errors to be written through the configured logger instead of directly to the console, when possible
- #17886 e747cba Thanks @matthewp! - Fixes the memory cache provider to skip responses with Vary: Cookie or Vary: *
- #17885 916b738 Thanks @Princesseuh! - Improves build performance for sites with a large number of pages coming from a large amount of different modules.
- #17795 15e2deb Thanks @matthewp! - Adds concurrent rendering support for experimental.incrementalBuild, including when using @astrojs/cloudflare
  
  Incremental builds no longer disable caching when build.concurrency is greater than 1. Projects that set build.concurrency: 1 to keep the cache enabled can remove that workaround. Cloudflare builds also reduce serialization overhead for large prerendered pages.
- #17879 21c34a6 Thanks @matthewp! - Fixes missing styles, links, and scripts from content collection entries rendered inside server islands
- #17861 3193988 Thanks @ethanstoner! - Fixes i18n fallback routes being generated with a corrupted path when the locale code also appears at the start of a later path segment. A page such as src/pages/en/enterprise.astro with fallback: { es: 'en' } produced the route /es/esterprise instead of /es/enterprise, so the fallback never matched the intended URL. Only the leading locale segment is rewritten now.
7.2.10
Aug 31, 2026
🐞 Patch Changes
- #17262 f8e9458 Thanks @Princesseuh! - Fixes @astrojs/markdown-remark being pinned to an exact version.
- #17874 10c7e63 Thanks @astro-factory! - Fixes SSR manifest placeholder not being replaced when the server build is minified, which caused a runtime Invalid URL crash at server boot
- #17869 2548abf Thanks @ematipico! - Fixes a case where the logger was improperly initialized at runtime in dev.
- #17878 76eff3d Thanks @ematipico! - Fixes browser heuristic caching for cached responses that include Last-Modified or ETag validators
- #17833 413a6e7 Thanks @astro-factory! - Fixes prerender conflict warnings to correctly identify the route that first rendered a duplicate pathname, instead of misattributing the conflict to an unrelated route that merely matches the URL pattern
- #17872 f7191cc Thanks @jx-grxf! - Fixes Markdown images in content collections rendering an empty srcset attribute when no responsive candidates are generated.
- #17755 157c500 Thanks @matthewp! - Fixes a bug where editing a content collection entry during astro dev on Windows kept serving stale content until the dev server was restarted. The data store now notifies the dev server directly after each write instead of relying only on the file watcher, which can miss the atomic rename that commits the write on some platforms.
- Updated dependencies [f8e9458, f8e9458]:
  - @astrojs/internal-helpers@0.11.0
  - @astrojs/markdown-satteri@0.4.0

🐞 Patch Changes
- #17846 b441180 Thanks @Princesseuh! - Fixes importing .html files not being typed outside of .astro files
- #17831 32e8b44 Thanks @astro-factory! - Fixes a crash when requesting /index.html against a dynamic page route like [slug].astro
- #17841 c35448e Thanks @astro-factory! - Fixes SSR manifest containing stale entryModules references to prerender-only chunks that no longer exist in the final build output
- #17847 eb87a23 Thanks @matthewp! - Fixes set:text escaping in MDX script and style elements
7.2.8
Aug 26, 2026
🐞 Patch Changes
- #17837 ecb4082 Thanks @matthewp! - Updates the minimum supported version of Sharp to 0.35.4
- #17786 db7c53b Thanks @gameroman! - Replaces the internal find-process dependency with a smaller, lighter alternative
7.2.7
Aug 25, 2026
🐞 Patch Changes
- #17415 55d38c8 Thanks @iseraph-dev! - Deserializes each route once when loading the SSR manifest
- #17772 023b48b Thanks @matthewp! - Fixes route selection for normalized request paths in adapter and development request handling
- #17819 633855b Thanks @matthewp! - Updates generated and default Cloudflare compatibility_date values to match the installed runtime and requires Wrangler ^4.125.0
- #17813 ae26d18 Thanks @matthewp! - Fixes rewrite() and next(payload) for GET and HEAD requests with host-provided bodies
- #17816 a0d2fe3 Thanks @astro-factory! - Fixes the experimental svgOptimizer not generating unique per-file ID prefixes when using SVGO’s prefixIds plugin
7.2.6
Aug 24, 2026
🐞 Patch Changes
- #17812 29af6da Thanks @matthewp! - Fixes a bug where new FetchState(request) could fail in development when server dependencies were optimized
7.2.5
Aug 24, 2026
🐞 Patch Changes
- #17758 5f419e2 Thanks @astro-factory! - Fixes a bug where experimental_getFontFileURL() rejected valid font URLs when using the Cloudflare adapter
- #17416 493796b Thanks @iseraph-dev! - Skips no-op pathname writes when normalizing SSR request URLs
- #17712 bd374b7 Thanks @fkatsuhiro! - Updates deprecation messages target from Astro 7 to 8
- #17719 dac1768 Thanks @astrobot-houston! - Fixes session ID validation to reject non-UUID cookie values before using them as storage keys
- #17770 84eb7e7 Thanks @astro-factory! - Fixes --mode, --site, --base, --out-dir, --verbose, --silent, and --open flags being silently dropped when using astro dev --background or astro preview --background
- #17713 d035290 Thanks @wakqasahmed! - Fixes content-modules.mjs not removing entries for deleted or renamed content files, which could cause Vite to attempt to resolve non-existent modules
  
  As part of this fix, #moduleImports is now fully rebuilt from deferredRender entries before every write, so a module import added only through the public addModuleImport() API without a corresponding deferredRender entry in the store will no longer be preserved across writes.
- #17743 adc750f Thanks @contactjawad! - Fixes Astro.preferredLocale and Astro.preferredLocaleList ignoring Accept-Language quality values when they are absent or 0. An entry without an explicit q= now correctly counts as quality 1.0 (per RFC 7231) and an entry with q=0 is treated as not acceptable, so the highest-quality locale is selected regardless of header order.
- #17757 660991c Thanks @astro-factory! - Fixes build errors showing wrong file location, missing line:col, and misleading hints when a plugin error (e.g. from MDX) is wrapped by Vite’s build error
- #17783 60b14ff Thanks @matthewp! - Fixes a type error when passing an image from a content collection image() schema to a component or <Image />. The schema returned by image() was missing the apng format, so it no longer matched the type of an imported image.
- #17664 d483125 Thanks @astrobot-houston! - Fixes an issue where Astro CSP support didn’t correctly handle cases "unsafe-inline" resource. Now when "unsafe-inline", Astro won’t emit hashes for the directive specified.
- #17810 0fc5f65 Thanks @florian-lefebvre! - Fixes a regression in the content collections that could cause images to not be resolved
- #17781 aa33b44 Thanks @matthewp! - Fixes memoryCache() storing responses that set cookies through Astro.cookies or Astro.session
- #17787 6661fbe Thanks @astro-factory! - Fixes server:defer crashing the dev server with “undefined is not a function” when a deferred component imports from astro:i18n
- #17750 dd0e3ac Thanks @dobrodob! - Fixes a regression where transition:persist stopped working for <audio> and <video> elements.
- #17774 fe1d16d Thanks @astro-factory! - Adds support for importing .apng files as image metadata for use with standard <img> elements. Astro’s image components reject APNG files to avoid removing their animation
- #17799 8797754 Thanks @astro-factory! - Fixes i18n fallbackType: "rewrite" returning 500 instead of 404 when the fallback locale also has no matching static path for a prerendered dynamic route
- #17741 99d3d3d Thanks @ericswpark! - Bumps the Astro compiler to the latest version. Changelog.
- #17782 3578d45 Thanks @Princesseuh! - Improves the performance of the Astro CLI in local by enabling Node’s module compilation cache.
- #17705 2043e4f Thanks @astrobot-houston! - Fixes incremental builds serving cached HTML that references stale CSS filenames after a stylesheet-only edit
- #17754 3d50dfd Thanks @astro-factory! - Fixes the dev server refusing to start in Docker containers after a restart due to PID reuse in the lock file check
- #17769 bbda94d Thanks @astro-factory! - Fixes a build failure when defining vite.environments.ssr in the Astro config. User-provided environment config for ssr, prerender, or client is now properly deep-merged with Astro’s internal environment settings instead of silently breaking the server entry naming.
- #17776 0874da8 Thanks @astro-factory! - Fixes the glob() content loader failing to load files with colons in their names (e.g., Guide: Architecture.md)

Aug 19, 2026
🐞 Patch Changes
- #17747 a90ff66 Thanks @Princesseuh! - Fixes builds hanging when an image file is malformed
- #17701 05763a0 Thanks @matthewp! - Fixes base path stripping to respect path-segment boundaries. With a configured base such as /docs, a request like /docs-archive/page is no longer treated as being under the base, so routing and context.url.pathname now agree on the same pathname.
- #17742 70b449d Thanks @Kjubikstronk! - Fixes astro build throwing TypeError: Missing parameter for dynamic routes when build.format: 'preserve' and trailingSlash: 'always' are used together. Stripping the framework-injected .html suffix dropped the trailing slash that the compiled route pattern requires, so the route no longer matched itself and its params resolved as empty.
- #17703 771b0a9 Thanks @astrobot-houston! - Fixes Astro.site always being undefined when rendering components via the Container API, even when site is set in astroConfig
- Updated dependencies [05763a0, bc171af]:
  - @astrojs/internal-helpers@0.10.4
  - @astrojs/markdown-satteri@0.3.7
  - @astrojs/markdown-remark@7.2.4
7.2.3
Aug 18, 2026
🐞 Patch Changes
- #17724 97140b2 Thanks @ematipico! - Fixes an issue where Astro could run out of memory when experimental.collectionStorage is set to chunked and there are multiple concurrent updates to the same collection.
- #17636 51723b1 Thanks @matthewp! - Fixes the dev server sometimes matching against stale routes after pages were added, removed, or renamed, requiring a dev server restart to pick up the change
- #17636 51723b1 Thanks @matthewp! - Fixes the composable request helpers (astro/fetch) throwing an error when used on a request that had been rewritten with Astro.rewrite() or next()
- #17636 51723b1 Thanks @matthewp! - Refactors Astro’s internal server-side request handling. This is an internal change: all documented public APIs, including App and NodeApp, keep their existing signatures and behavior.
  
  The undocumented internal app.pipeline property and the AppPipeline export from astro/app have been removed. Adapters that used app.pipeline.getLogger() to wait for the configured log destination can call the new app.getLogger() instead.
  
  As a result of this refactor, new FetchState(request) from astro/fetch now works anywhere inside a built Astro server — including custom src/fetch.ts entrypoints — without the request needing to first pass through app.render(). Previously this threw an error, breaking patterns like the Cloudflare adapter’s advanced custom-worker setup.
- #17723 c3b9aed Thanks @florian-lefebvre! - Fixes a link in font providers JSDoc annotations
- #17699 e28d227 Thanks @ArmandPhilippot! - Fixes several documentation issues related to the JSDoc for configuration options.
  - When hovering over the server and fonts options, the JSDoc for the nested options was displayed instead of the JSDoc for the top-level property.
  - Two i18n configuration options were being used incorrectly in the examples.
  - The indentation of some code blocks was broken on hover.
- #17572 2066f39 Thanks @matthewp! - Fixes a crash when a request arrives with a malformed port in the Host header (for example example.com:65536 or example.com:8080:8080). Such a host made the constructed request URL invalid, and the fallback that was meant to recover reused the same invalid host and threw again. The request URL now degrades to a host the server controls when the incoming host cannot be parsed, so the request is handled instead of erroring.
- #17685 9f15609 Thanks @astrobot-houston! - Fixes a dev server error where an SSR full reload triggered by a third-party Vite plugin (such as @tailwindcss/vite) could fail with Failed to load url astro:server-app.js
- #17636 51723b1 Thanks @matthewp! - Improves error handling for custom log destinations. When the configured logger fails to load, Astro now reports the error and continues with the default console logger instead of failing the first request.
- #17631 cf29bec Thanks @matthewp! - Fixes getCollection() and getEntry() throwing DataCloneError when a collection schema transform returns a Temporal.PlainDate or other class instance.
- Updated dependencies [8c193f6]:
  - @astrojs/internal-helpers@0.10.3
  - @astrojs/markdown-remark@7.2.3
  - @astrojs/markdown-satteri@0.3.6
7.2.2
Aug 13, 2026
🐞 Patch Changes
- #17611 9bc3207 Thanks @thelazylamaGit! - Fixes component styles rendered from content entries remaining stale until a second save when an adapter uses Astro’s fallback development environment
- #17634 2267eee Thanks @astrobot-houston! - Fixes incremental builds dropping optimized images for cached pages when using a collectStaticImages prerenderer (e.g. @astrojs/cloudflare with compile-time image optimization)
- #17650 4cdf128 Thanks @astrobot-houston! - Fixes intermittent ImageNotFound errors during build on projects with many images. The build now limits concurrent image file reads to avoid exhausting OS file descriptors (EMFILE) and retries transient I/O errors with backoff. Non-transient errors are no longer silently swallowed.
- #17683 2378221 Thanks @astrobot-houston! - Fixes prerenderConflictBehavior not applying to content collection duplicate ID warnings in the glob() and file() loaders. Setting it to 'error' now throws during content sync, and 'ignore' suppresses the warning.
- #17659 90c6ea4 Thanks @astrobot-houston! - Fixes the Fonts API breaking experimental.incrementalBuild caching by embedding a build-local, randomly-assigned server port in generated code used for the dependency hash
- #17630 fd1d9ee Thanks @ericclemmons! - Fixes incremental builds becoming prohibitively slow for sites with many pages or content entries that share a large dependency graph.
- #17690 93beecc Thanks @NgoQuocViet2001! - Prevents files in directories whose names start with pages from being treated as page routes
- #17671 09f0dc7 Thanks @tarikermis! - Fixes astro dev refusing to start after a Docker container restart when an unrelated process reuses the PID from a persisted lock file. Astro now checks the process command across platforms, so stale lock files are cleaned up and --force does not signal the unrelated process.
7.2.1
Aug 11, 2026
🐞 Patch Changes
- #17612 7133730 Thanks @thelazylamaGit! - Fixes CSS hot module replacement after navigating between pages with ClientRouter
- #17628 4ada248 Thanks @astrobot-houston! - Fixes a CSP violation when using both security.csp and experimental.clientPrerender with data-astro-prefetch links. The dynamically injected <script type="speculationrules"> now uses a static "source": "document" approach with a CSS selector, producing a deterministic payload that is hashed and included in the CSP script-src directive at build time.
- #17605 89e4647 Thanks @ashleigh-yeoman! - Fixes middleware HMR not responding to changes in imported modules. Previously, only direct edits to the middleware file would trigger a reload.
- #17582 bd2c1a5 Thanks @astrobot-houston! - Fixes a regression where content collection reference() fields silently accepted entry IDs that don’t exist, such as an ID that doesn’t match a loader’s slugified version of it. Astro now logs an error for references that point to a missing entry after all loaders finish syncing.
- #17661 97b0cc7 Thanks @ArmandPhilippot! - Improves Markdown options documentation with links to the Markdown guide and official processors.
- #17349 4328c73 Thanks @astrobot-houston! - Fixes an issue where requests handled by the dev prerender environment (e.g. /_image with @astrojs/cloudflare’s prerenderEnvironment: 'node') returned a 500 when a prerendered catch-all route existed, because non-prerendered route modules were imported in an environment where their runtime-specific APIs are unavailable
- #17603 722eed6 Thanks @astrobot-houston! - Fixes <video> and <audio> elements being non-functional after navigating via view transitions (<ClientRouter />)
- #17616 3a890d2 Thanks @lazerg! - Fixes experimental.incrementalBuild re-rendering unchanged routes that import more than one asset. The route’s dependency hash depended on the order the assets finished building, so two builds of identical sources could produce different hashes. The hash is now based on the file name each asset resolves to.
- #17547 fba468c Thanks @dmgawel! - Improves getCollection() and getEntry() performance for entries without local image references
- #17602 16e0d9d Thanks @astrobot-houston! - Fixes a build error caused by hash collisions in generated content collection image import identifiers
