The latest release of Document Exchange is 05.02.03. The change list is as follows:

Fix: DMXPanel was not correctly reacting to the ViewPermission parameter
Fix: Manual activation screen was not working on some versions of DNN
Enhancement: hardened delete code. It should now be near impossible to lose any document during any kind of delete.
Fix: Document migration code could time out
Fix: S3 was throwing errors on upload of files with space in name
Fix: digest authentication would not succeed if username had special characters in it
Fix: AND advanced search did not accurately produce results
Fix: secondary admins could not see icons on template view - complete replace of DNN userinfo with dmx userinfo
Fix: disabled client side caching of downloads which could have led to version confusion
Fix: extension rename scripts were pointing to the wrong type definition. Should now run fine.
Enhancement: Fallback for alternative storage providers. If not available the file will be stored on disk.
Fix: renamed DMX's RadUpload module to keep it separate from DNN's new RadUpload

Note that on DNN 5.2+ installations the web.config has an entry for a RadUploadModule for the DNN core. The name of this module conflicted with the DMX version of the same component. So that is renamed during the upgrade to make sure DMX's RadUpload stays out of the hair of the DNN RadUpload.
