Version 1.0 has a significant change from previous versions. AccessController is dropped in favor of a module actually called SiteControl. This makes the whole system work better in the Perl sense, and make version checking and installation smoother with CPAN. To upgrade: 1) Edit all of your modules that depend on Apache2::SiteControl::AccessController, and change them to use Apache2::SiteControl. 2) Make the same change in all of your pages. i.e.: $user = Apache2::SiteControl::AccessController->getPermissionManager($r) becomes: $user = Apache2::SiteControl->getPermissionManager($r) i.e. perl -pi'.bak' 's/SiteControl::AccessController/SiteControl/' *.html
