This morning DotNetNuke 4.9.4 Community Edition version was released. We haven't tried it yet but general comments say that the upgrade is doing well with no problems.

While DNN corp original intention was to release the 4.9.4 Professional Edition a few weeks after the Community Edition they have since realized that this doesn't work from a practical perspective. All users, whether Professional Edition customers, or Community Edition users, have a desire to download the current version as soon as possible. When security issues are involved, this is even more critical as having delayed releases poses a security risk.

As a result, DNN's plan is to eventually release both versions simultaneously.
