Introduction

MSNP8 is the seventh released version of the Mobile Status Notification Protocol.
It was introduced officially in Client Version 5.0.0537.

Command information

No commands for any service were known to be introduced in this version

The following commands were removed in this version:

  • INF (automatic disconnection)
  • FND (502 by July 2003, see Known changes for client details.)

Known changes

(from MSNP7):

  • CVQ: Client codebase identification parameter is no longer empty.
  • Being the first protocol split, all released clients that support MSNP8 do not support any previous versions.
  • Login process is now VER-CVR-USR instead of VER-INF-USR.
  • USR OK has a new parameter, Account restriction status, if set to 1, the Official Client will forcefully log out and demand that you log in using MSN Explorer instead.
    Unrestricted accounts (those that do not need to log in using MSN Explorer) will have the value set to 0 instead.
  • Introduced TWN authentication method, which uses Passport 1.4 over HTTPS.
  • Reworked SYN and related response commands (notably LSG and LST) drastically:
    • Iterators are gone, now total size of both groups and total contacts included in SYN response.
    • All transaction IDs and list versions have been removed from response commands (now treated as asynchronous commands).
    • Unset properties (PRP commands) are now omitted. Hurray.
  • CVR request now has a new 8th parameter, which is the current user. This also applies to CVQ in CVR0.
  • New initial profile fields: ClientIP and ClientPort.
    ClientPort needs to be endian swapped for it's correct value. Formula: y = (((x & 0xff) * 256) + ((x & 0xff00)/256)).
  • NOTE: FND might still exist in client, but theres no way of triggering it. Practically removed. All previous protocol versions also received the 502 error code.
  • BPR removes related user, for some reason, default fields share same optimization as PRP does.
  • LST (for SYN): Lists are now all combined into a single number, where: 1 = Forward List (FL), 2 = Allow List (AL), 4 = Block List (BL), 8 = Reverse List (RL), For example, a contact on the Forward List (FL), Allow List (AL) and Reverse List (RL) would have their combined list number be 11.
  • CHG, ILN, NLN: Client Capabilities are introduced. You can now tell other clients what features you support.
  • Official Client: Connectivity field added to application requests to notify the other user about what the network conditions are.
  • Official Client: Introduced support for the Address Book Service. The URL is gathered from svcs.microsoft.com. abch_config.asp provides an XML document with a <abchconfig> element.
    It has a <url> element containing the service URL, a <refresh> element, and finally a <percent> element. Example values are http://contacts.msn.com/abservice/abservice.asmx, 0 and 0.0 respectively.
  • Official Client: Added new URL services ADDRBOOK, ADVSEARCH and INTSEARCH
