Minor Changes

• #15589 b7dd447 Thanks @qzio! - Adds a new security.actionBodySizeLimit option to configure the maximum size of Astro Actions request bodies.

  This lets you increase the default 1 MB limit when your actions need to accept larger payloads. For example, actions that handle file uploads or large JSON payloads can now opt in to a higher limit.

  If you do not set this option, Astro continues to enforce the 1 MB default to help prevent abuse.

  // astro.config.mjs export default defineConfig({ security: { actionBodySizeLimit: 10 * 1024 * 1024, // set to 10 MB }, });

Patch Changes

• #15594 efae11c Thanks @qzio! - Fix X-Forwarded-Proto validation when allowedDomains includes both protocol and hostname fields. The protocol check no longer fails due to hostname mismatch against the hardcoded test URL.
