- Patch #228594 by catch et al: removed access rule functionality from core.
The access rules capability of user module has been stripped down to a simple method for blocking IP addresses. E-mail and username restrictions are now available in a contributed module. IP address range blocking is no longer supported and should be done at the server level. This patch is partly motiviated by the fact that at the usability testing, it frequently came up that users went to "access rules" when trying to configure their site settings.
