+	  <p>The matrix team releases Synapse 1.2.1 as a critical security update. It contains patches relating to redactions and event federation:</p>
+	  <ul>
+	    <li>Prevent an attack where a federated server could send redactions for arbitrary events in v1 and v2 rooms.</li>
+	    <li>Prevent a denial-of-service attack where cycles of redaction events would make Synapse spin infinitely.</li>
+	    <li>Prevent an attack where users could be joined or parted from public rooms without their consent.</li>
+	    <li>Fix a vulnerability where a federated server could spoof read-receipts from users on other servers. </li>
+	    <li>It was possible for a room moderator to send a redaction for an m.room.create event, which would downgrade the room to version 1.</li>
