I've always had a 'use_xcache' line in my conf_global.php file to instruct use of xcache. Now this has settings via ACP, can this line be removed from conf_global.php?

Yes, the conf_global.php setting will have no effect.

OK thanks. While we're at it, is there anything else here surplus to requirements?. . .

?>

_jsDebug has no effect any more.  After upgrade, neither does banned_group.

The IN_DEV definition should be moved to constants.php from conf_global.php.

 use_friendly_urls should be removed.
