Reviews for this release

Great upgrade, seamless.

A very stable release. In my opinion DNN is getting very mature now and a real option to use in a production environment. I hope in future releases it will be possible to have more control over the html that is generated and the css. I'm working on a skin for the moment and it is still hard to overrule all DNN CSS.

I had no problems upgrading from DNN 4.5.5

Do not use. As a seasoned DNN developer and admin, I can say that the upgrade version will not work on even the simplest sites. The install wizard hasn't changed over two years and is still plagued with the same bumps. I cannot stress the importance of a backup of your site and database - trust me, you'll need them. In my opinion, another garbage installation served fresh for the community.

Localization.GetString method can not work well if the module folder name contains symbol "."

Upgrade from 4.9.2 ran flawlessly. At first, some of my users were getting PAGE_LOAD_EXCEPTIONS that appeared to have to do with Javascript or "Exception has been thrown by the target of an invocation" --- They couldn't login. They couldn't see the menu. After they cleared their cache and restarted computer, the page started working again. Lesson: EXCELLENT release, tell users to clear cache!
