     <h1>Agent-JS Changelog</h1>
 
     <section>
+      <h2>Version 0.12.0</h2>
+      <ul>
+        <li>
+          Changes the certificate verification interface and fixed its logic. The constructor now
+          takes a root key, and verification takes a canister ID. Additionally, verification now
+          checks that the delegation is authoritative for the given canister ID.
+        </li>
+      </ul>
       <h2>Version 0.11.2</h2>
