Forum version 4.5.3 is now available for download. This release is huge, so please make sure you really check this out (ie. test) before diving into production updates as the interface has changed somewhat and there are many more options available than in previous versions. Overall, this release is a great step forward and fixes many (if not all) the previously verified issues. This release will work with DNN core versions 4.8.1 or greater.
Beyond the bug fixes, areas that were found to hinder performance in larger installations have been refactored in order to enhance performance. Another primary area of focus was the end user experience, including moderators. In order to accomodate users a move to Ajax has been implemented across the entire module. For those sites that still do not use Ajax, the module will run as expected and the user interface will look almost identical as those sites using Ajax. To accomodate feature requests, several new features have been added such as: Role Avatar support, User Banning, Post Reporting Details, Direct Post Links w/ Anchors, Admin/Moderator/User Control Panels, Per Forum RSS Enable/Disable, Support for Multiple Attachments, Support for Inline Post Image Attachments, Per Forum FROM Notification Email Addresses,
More Control Over Email Queue, Subforum Support, Thread Bookmarking, Simpler Notification Management (from a single spot), Support for Limiting Post Edit Period, My Posts Support, Search Keyword Highlighting, New Private Messaging Outbox, Jump to Last Unread Post Support, Ability to view latest threads by time frame and more.
If you use the Extensions for the module (Latest Posts, any previous themes, etc.), you may want to hold off until Monday as I won't have this available until late Sunday for you and as per usual will then be available on www.dnnforums.com, which is also where you can preview the module using a custom theme.
I am going to keep a list of 'known' issues in a pinned thread over in the forums. I will update this when I have verified issues. You can see this here: http://www.dotnetnuke.com/Community/Forums/tabid/795/forumid/7/postid/320518/scope/posts/Default.aspx
