As you probably already know, versions 7 and below of the MSN Messenger protocol will be disabled as of October 15th. We expect that clients supporting version 8 and above will continue to function, and documentation about the changes in MSNP8 are available. We intend to integrate this information into the rest of the site eventually.

The new version of this website (you are currently looking at it) was officially published today. However, the old version is still kept online for nostalgic purposes.
