…k refuses 7 Lock file maintenance moved astro from 7.3.3 to 7.3.5, and typecheck failed in calendar-visualizer, davidjfelix.com, and djf.io: since 7.3.4 (withastro/astro#18053) `astro check` resolves typescript from the app directory before it looks for @astrojs/check and refuses to run when that is 7, so the workspace-root @astrojs/check + typescript 6 seam from 2026-08 no longer helps. The three Astro apps now pin typescript 6.0.3 and declare @astrojs/check themselves, the same hold the Svelte and Nuxt apps carry; the workspace root drops its devDependencies, and renovate's sub-7 hold covers the Astro apps again. The lockfile diff is that move alone. Also bump every Biome config's $schema from 2.5.10 to the pinned 2.5.14 CLI, which silences the schema-version notice each lint task printed.

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](withastro/astro#18086) [`795a7e4`](withastro/astro@795a7e4) Thanks [@ump45nose](https://github.com/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](withastro/astro#18074) [`0429805`](withastro/astro@0429805) Thanks [@SurefireStudios](https://github.com/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](withastro/astro#18007) [`2245837`](withastro/astro@2245837) Thanks [@L4XB](https://github.com/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](withastro/astro#18096) [`43657c4`](withastro/astro@43657c4) Thanks [@matthewp](https://github.com/matthewp)! - Fixes domain-based i18n routing to respect `security.allowedDomains` when selecting a locale from request host headers - [#18043](withastro/astro#18043) [`8a53a8b`](withastro/astro@8a53a8b) Thanks [@astro-factory](https://github.com/apps/astro-factory)! - Fixes `image.responsiveStyles` emitting invalid `object-position` CSS values for same-axis keyword pairs (`top bottom`, `left right`, etc.) - [#18029](withastro/astro#18029) [`c08252d`](withastro/astro@c08252d) Thanks [@matthewp](https://github.com/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. - Updated dependencies \[[`3fd16ee`](withastro/astro@3fd16ee), [`8358d59`](withastro/astro@8358d59)]: - [@astrojs/markdown-satteri](https://github.com/astrojs/markdown-satteri)@0.4.2 </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
