Bump astro from 5.18.2 to 6.4.6

[dependabot]

Bumps astro from 5.18.2 to 6.4.6.

Release notes

Sourced from astro's releases.

astro@6.4.6

Patch Changes

• #16765b10e86e Thanks @​fkatsuhiro! - Fixes an issue where renaming an image file while the dev server is running triggers a build error. Now Astro correctly hot-reloads the image without crashing.

• #17026add3df1 Thanks @​matthewp! - Hardens addAttribute to drop attribute names containing characters that are invalid per the HTML spec (", ', >, /, =, whitespace)

• #17033ffda27b Thanks @​matthewp! - Validates the request origin against allowedDomains before fetching prerendered error pages. When allowedDomains is configured and the Host header matches, the original origin is used. Otherwise, the fetch falls back to localhost.

astro@6.4.5

Patch Changes

• #169854ecff32 Thanks @​maximslo! - Fixes the experimental.logger destination not being used for the "Server listening on..." startup message. The logger is now resolved before the server starts listening, and adapterLogger re-creates itself when the underlying logger changes so the startup message uses the correct destination.

• #16947e0703a6 Thanks @​ematipico! - Fixes Astro.request.url not reflecting validated X-Forwarded-Proto/X-Forwarded-Host headers when security.allowedDomains is configured. Previously, only Astro.url was updated with the forwarded origin while Astro.request.url retained the socket-derived URL, causing the two to diverge behind TLS-terminating proxies.

• #16997dc45246 Thanks @​matthewp! - Reverts a change to isNode runtime detection that caused a significant build time regression for Cloudflare adapter users with large prerendered sites

6.4.4

Patch Changes

• #169261b39ae8 Thanks @​narendraio! - Prevents App.match() from throwing on request paths that contain an invalid percent-sequence.

• #169242c0bc94 Thanks @​astrobot-houston! - Fixes an issue where editing a client-side component (e.g. with client:idle, client:load, etc.) caused an unnecessary full program reload of the backend during development.

• #169582c1d50f Thanks @​fkatsuhiro! - Fixes a bug where static file endpoints using getStaticPaths with .html in dynamic param values (e.g. { path: 'file.html' }) would fail with a NoMatchingStaticPathFound error during build. The .html suffix is no longer incorrectly stripped from endpoint route pathnames.

• #16855c610cda Thanks @​astrobot-houston! - Fixes dynamic routes returning 500 "TypeError: Missing parameter" when using domain-based i18n routing in SSR.

• #16946606c37b Thanks @​ematipico! - Fixes Astro.routePattern to preserve original casing of dynamic parameter names from filenames. Previously, a file at src/pages/blog/[postId].astro would return /blog/[postid] for Astro.routePattern due to an internal .toLowerCase() call. It now correctly returns /blog/[postId].

• #1672016d49b6 Thanks @​thomas-callahan-collibra! - Fix an issue where dynamic routes would return the string [object Object] instead of the expected content, in certain runtimes.

• #1670317390a6 Thanks @​henrybrewer00-dotcom! - Fixes styles being stripped when the project root is started with a path whose case differs from the actual filesystem case (e.g. running astro dev from d:\dev\app while the folder on disk is D:\dev\app).

• #16855c610cda Thanks @​astrobot-houston! - Fixes Astro.currentLocale returning the default locale instead of the domain's locale on dynamic routes served from a mapped domain.

6.4.3

Patch Changes

• #1690017a0fbd Thanks @​ocavue! - Bumps devalue dependency to v5.8.1

• #160160d85e1b Thanks @​felmonon! - Fix a false positive in the dev toolbar accessibility audit for anchors with text inside closed <details> elements.

• #1691179c6c46 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.
