information for MSNP4 found: adds the client codebase parameter to SND and CVR (and an empty to CVQ, but that lasted all the way to MSNP7 lol, does that for MSNP3 fallback too which is kind of funny)
18 commands left.
USR is very big and would consider a break here
... Why does the spec imply that Switchboard has INF? Is that why every client implements it after MSNP8?
the relevant strings exist in 3.6.003x, but are they actually used? in MSNP7+ clients they are, but i'm wondering about MSNP6 exclusively here.
Information also needed: What shows the "Account needs to be verified before using the service" dialog? it's not 924, it's not implemented.
