# Known changes

(from MSNP12):

• This is the second protocol split since MSNP8.
  No clients supporting this protocol are expected to support MSNP12 or below.
• XFR NS format has been changed.
  The unused parameter from MSNP3 and the current server parameter from MSNP7 have been replaced with two new parameters, one containing U, and one containing a D.
  The use of these parameters is unknown.
• The Passport Request Security Token service authentication request will now include a request for few more security tokens, notably contacts.msn.com for the Address Book Service.
• Replaced SYN with both the Address Book Service's ABFindAll and the Contact Sharing Service's FindMembership actions.
• Instead of ADC adding new users to the Forward List (FL), Allow List (AL), Block List (BL), or the Reverse List (RL), the Address Book Service's ABContactAdd action is used for the Forward List (FL), and the Contact Sharing Service's AddMember action for the other lists.
• Instead of REM removing existing users from the Forward List (FL), Allow List (AL), Block List (BL), or the Pending List (PL), the Address Book Service's ABContactDelete action is used for the Forward List (FL), and the Contact Sharing Service's DeleteMember action for the other lists.
• Instead of GTC, use the Address Book Service's ABContactUpdate action on your own user to set the MSN.IM.GTC annotation's value to 0 or 1:
  • 0: Automatically add to AL
  • 1: Ask before adding to AL/BL
• Instead of ADG, use the Address Book Service's ABGroupAdd action.
• Instead of RMG, use the Address Book Service's ABGroupDelete action.
• Instead of REG, use the Address Book Service's ABGroupUpdate action.
• Instead of SBP, use the Address Book Service's ABContactUpdate action.
• NOT: <NotificationData> notifications are used for updates to your contact list as well as ADL.
• GCF: All policies are now always sent after your first USR command, including the contents of Shields.xml in the policy with the type of SHIELDS.
• UUX, UBX: Added <MachineGuid> element to <Data>.
• The contact management commands (ADL and RML) now only manage the state of the Forward List (FL), Allow List (AL) and Block List (BL) for the current session.
  For managing contacts persistently, you have to use both the Address Book Service and the Contact Sharing Services SOAP services.
• RNG and XFR SB commands now have two extra parameters.
  The use of these parameters is currently unknown.
• Offline instant messages can now be sent via the Offline Instant Messaging SOAP service.

The Client now uses both the ABFindAll and the FindMembership actions to get the current state of all lists and the last stored name and privacy mode.

NOTE: The following ADL and UUX payloads have been exploded for visibility and formatting reasons.
No whitespace is allowed in ADL's payload and the payload size reflects this, and is set to the correct value.
