+      <p>
+        The PHP security team would like to give advance notice of an upcoming
+        security release, scheduled for Wednesday, 21 October 2026 at 14:00
+        UTC. It addresses two critical vulnerabilities, both rated CVSS v4.0
+        9.2.
+      </p>
+      <p>
+        All PHP users are encouraged to prepare now so they can upgrade as
+        soon as the release is available.
+      </p>
+      <p>
+        We reserve the right to release earlier should details of either
+        vulnerability become public, or should evidence of active exploitation
+        appear in the wild.
+      </p>
+      <p>
+        Full details, affected versions, and the fixed versions will be
+        published with the release.
+      </p>
+      <p>
+        Thank you for helping us keep PHP secure.
