after upgrade from 1.0.x to 1.1.x i see filesystem_attachments is default loaded, even in my config.inc.php is not defined as wanted to be loaded, is plugins now not optional ?

jqueryui and one of *_attachments plugins is required. So, if you do not specify them in the config it will load jqueryui and filesystem_attachments.
