you can find the RadEditor for MOSS Release History.
For convenience I pasted the Release History bellow:
Changes in version 4.52 (03/26/2008)
- FEATURE: updated content provider. When the paths in the editor config file start with a slash, the provider will look in the root of the site collection. When the paths do not start with a slash (e.g. only a library name), the provider will look in the current web.
- BUGFIX: exception when opening the built-in image manager dialog.
- BUGFIX: exception when activating the editor features.
- BUGFIX: the list editor will now automatically remove the extra <div> elements, which SharePoint adds around the content.
- BUGFIX: the editor will no longer display the previous content on list fields with "append only" set to true and enabled versioning.
I hope this helps.
