### Patch Changes

- [#18475](https://github.com/withastro/astro/pull/18475) [`cf27e70`](https://github.com/withastro/astro/commit/cf27e70a9057ce29ade2a8a843bd9275a696e9ab) Thanks [@ematipico](https://github.com/ematipico)! - Bumps the minimum supported Node.js version to 22.23.4, which includes the fixes from the [October 2026 Node.js security releases](https://nodejs.org/en/blog/vulnerability/october-2026-security-releases)
  
  This is a patch release because the [Node.js support and upgrade policy](https://docs.astro.build/en/upgrade-astro/#nodejs-support-and-upgrade-policies) allows the Core team to raise the minimum Maintenance LTS version in a patch release when a disclosed and fixed Node.js security flaw affects Astro.
