Custom fields totally changed??

Hi,

I just updated to 0.16.2 from 0.15.x. Apparently the whole custom fields 
mechanism has changed. I got a whole website running with them, seems I 
have to change a lot now, I suppose the whole array that gets returned 
with the getUsers methods will be different too.

Is there any documentation what changed and how it works now. Just the 
config array layout doesn't give me any clue. What do the alias, fields 
and tables subarrays do and where go the original 'optional_fields' and 
custom_fields sub arrays from version 0.15??

All these nested arrays are chinese to me
'authContainers' => array(
             'DB' => array(
                 'type'          => 'MDB2',
                 'loginTimeout'  => 0,
                 'expireTime'    => 3600,
                 'idleTime'      => 1800,
                 'allowDuplicateHandles' => 0,
                 'storage' => array(
                     'dsn' => $dsn,
                     'alias' => array(
                         'lastlogin' => 'lastlogin',
                         'is_active' => 'is_active',
                     ),
                     'fields' => array(
                         'lastlogin' => 'timestamp',
                         'is_active' => 'boolean',
                     ),
                     'tables' => array(
                         'users' => array(
                             'fields' => array(
                                 'lastlogin' => false,
                                 'is_active' => false,
                             ),
                         ),
                     ),
                 )
             )
         ),


TIA a lot!!
