 * **Core** Aligned the runtime PHP and WordPress guards with the published minimum requirements.
+* **ESI** Prevented Guest Mode pages from creating ESI subrequests when an integration registered its ESI hooks before Guest Mode detection.

 * **Image Optimize** Fixed a fatal error when the WordPress HTTP fallback could not download an image.
 * **Image Optimize** The image optimization callback is now verified by a QUIC.cloud signature instead of the source IP address, and every notified download location is validated before use.
