Known changes

(from MSNP5):

USR OK now has a verified bit (parameter 4), if it is 0, the Official Client shows a warning to verify the account. NOTE: Your display name will be forced to be example@hotmail.com (E-Mail Address Not Verified), and can not be changed.
Client-server challenges were introduced. The format for the response (QRY commands) are MD5(challenge + privateKey) as a lowercase hexadecimal string.
An example Private Key is Q1P7W2E4J9R8U3S5, which is tied to the Public Key of msmsgs@msnmsgr.com.
First protocol version added in a patch release (Client Versions 3.6.0025 and 3.6.0026 do not support MSNP6).
Official Client: Added new URL services PROFILE, N2PACCOUNT and N2PFUND.
Official Client: Error 924 dialog changed to the unverified but still can use service one. Not sure why.
