+      <para>
+        Implemented globally unique IDs for MySQL servers. A UUID is now
+        obtained automatically when the MySQL server starts. The server
+        first checks for a UUID written in the
+        <filename>auto.cnf</filename> file (in the server&apos;s data
+        directory), and uses this UUID if found. Otherwise, the server
+        generates a new UUID and saves it to this file (and creates the
+        file if it does not already exist). This UUID is available as
+        the <literal role="sysvar">server_uuid</literal> system
+        varibable.
+      </para>
+
+      <para>
+        MySQL replication masters and slaves know each other&apos;s
+        UUIDs. The value of a slave&apos;s UUID can be read on the
+        master as the system variable
+        <literal role="sysvar">slave_uuid</literal>, as well as in the
+        output of <literal role="stmt">SHOW SLAVE HOSTS</literal>. After
+        a slave is started (with <literal role="stmt">START
+        SLAVE</literal>), the value of the master&apos;s UUID is
+        available on the slave as the
+        <literal role="sysvar">master_uuid</literal> system variable, as
+        well as in the output of <literal role="stmt">SHOW SLAVE
+        STATUS</literal>.
