what do you mean? does aceSEF require legacy mode?
ETA:
well since I just received the message about the new release I uninstalled version 1-0-6.
only after an uninstall error that didn't get into any details whatsoever (folders in components and admin have been deleted as well as the 3 tables)
I am now unable to installe either version.
I get sql errors with both of them. and that did happen during installation is the creation of the 3 tables however they are empty and none of the folders is present.
