Most visible change of these versions is,

--- horde52.0408/imp/docs/CHANGES
+++ horde52.0410/imp/docs/CHANGES
@@ -2,6 +2,8 @@
 v6.2.0-git
 ----------
 
+[mms] Ensure that viewing large mailboxes does not overload the session
+      storage size.
 [mms] Implement web notifications for new mail alerts.
 [mms] Add bare address information to title attribute in viewport on dynamic
       mailbox page

and introduce Horde_Core_Cache_Session class.

The code of Horde/Core/Cache/Session.php from line 53 is,
        parent::__construct(array_merge(
            array(
                'app' => 'horde',
                'maxsize' => 5000,
                'storage_key' => 'sess_cache'
            ),
            $params
        ));
set maxsize to 5000.

I changed this value to 100000, 
then critical number of messages is increased to 4600 from 200.
