version 4.6 stable is now available. It provides several bug fixes, you can find the complete list in the change log.
The security alert is about the documentation:
"The documentation section about multiple instances of DaDaBIK has been (at least for the moment) removed. That section was not up-to-date and referred to a version of DaDaBIK which still didn't have the authentication feature: the result is that if users followed those instructions having authentication ON, a user authenticated on the first (not admin) instance could also access the /admin instance without authentication. This is not a proper bug but could lead to a false sense of security."
DaDaBIK 5 will be available in about two weeks; having about twenty new features, it will bring users to a new level in terms of Web Database Application Rapid Development
