With the release of IE7 Beta 3 the RSS Platform has been API complete, meaning we don't anticipate making breaking changes to the API going forward. We have been holding true to that goal in IE7 RC1, there have been no breaking changes to the RSS Platform API in RC1.

Using the API from script and/or managed code is quite trivial b/c the type information is readily available for those languages.

However, when using C++ to access the RSS Platform it's preferable to have the header file and/or the type library (.tlb). The msfeeds.h and msfeeds.tlb are included in the Windows SDK. I can understand that not everyone is willing to install the entire Windows SDK (RC1 download) just to get the msfeeds.h header file, so I put together

RSS Platform - Mini SDK

which includes the necessary headers to get you started. Just add the header files to your project and include msfeeds.h in your source file.

Don't be concerned that the name of the zip file contains the words "Beta 3". Since the API hasn't changed in RC1 since Beta 3, the Beta 3 header is still valid. Give it a try and let me know what you are using the RSS Platform for.
