Astro: astro@7.3.4 Release

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.
