Astro 7.3.2

Astro 7.3.2 shipped on September 8, 2026, a focused patch release on top of the 7.3 branch. It is available now on npm for existing Astro projects.

What Changed

The headline fix in 7.3.2 targets the dev toolbar. The toolbar could return a 504 "Outdated Optimize Dep" error when a workspace-linked package imported a dependency that Vite's initial scan did not discover. Because the dependency was never part of the first optimization pass, the toolbar request failed until a full reload re-ran the scan. This release resolves that edge case so linked, monorepo-style packages render their toolbar reliably on the first load.

Context from the 7.3 Series

7.3.2 lands shortly after 7.3.0 and 7.3.1. The 7.3.0 minor added an --ignore-lock flag to astro preview, which lets multiple preview servers run side by side on different ports, a convenience for E2E testing workflows such as Playwright. It also corrected a locale fallback routing bug in which a page such as src/pages/en/enterprise.astro with fallback: { es: 'en' } produced /es/esterprise instead of /es/enterprise. Only the leading locale segment is now rewritten, so the fallback matches the intended URL.

Deprecations and Fixes

• Dev toolbar 504 — Outdated optimize-dep errors for workspace-linked imports are now avoided.
• Preview flags — The new --ignore-lock option supports concurrent preview servers.
• i18n fallbacks — Fallback routes only rewrite the leading locale segment.

There are no breaking changes in 7.3.2, so upgrading is a routine package bump: npm install astro@latest.
