Microsoft is going to end the mainstream support for SharePoint 2007 (MOSS) on October 9th, 2012 (see on the official support lifecycle page), we also stopped the development of RadEditor for MOSS, just like we followed suit with the support for .NET 2.0.
The last official release of RadEditor for MOSS is version 5.8.16 (Q2 2012), which is based on Telerik's ASP.NET Editor (version 2012.2.607). The RadEditor for MOSS build is using a .NET 2.0 version of Telerik.Web.UI. Since we are no longer maintaining a .NET 2.0 build, we cannot have new versions of the MOSS editor. Please keep in mind that support for integrating newer versions of the
Telerik.Web.UI in MOSS is not provided by Telerik. This includes new API
and functionality added in the RadEditor for ASP.NET AJAX after Q2 2012.
Nevertheless, existing users can upgrade to a newer version of RadEditor by using the latest MOSS build (5.8.16) and adding the updated Telerik.Web.UI.dll manually. To do this follow the steps below:
"Telerik.Web.UI, Version=20xx.x.xxx.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4"
