Please note two very important changes with this release:
1. In OGUR Settings, the "Default Group Member" and "Default Founder" role assignments have been modified. They are now assigned by "Group Type". So, if you have your OGUR configured to assign a default group member and/or default founder roles, you must re-edit these settings when after you install the OGUR 6.x-1.5 release.
2. Some permissions have been modified. In particular, several new permissions have been added:
"auto assign group roles"
"configure restricted member roles"
"ogur perm 01 - 10"
Please see http://drupal.org/node/397954 for details. In general, group roles which are allowed to create default basic group or registration code role assignments now require the "auto assign group roles" permission.
