This command is used to send information about the client and it's operating system to the server. For the official client, the server then responds with the recommended version of the client to use, the minimum safe version as well as 2 URLs, one a link to the download page for the updated version and one to a page with information about the updated version. If the client is unrecognised by the server, the recommended version is 1.0.0000 and the minimum version is the version number sent by the client in the initial CVR.

Both CVQ and CVR seem synonymous with each other in MSNP and are used interchangeably in this article.

CVR trid rec_ver rec_ver2 min_ver dl_url info_url
=== Parameters ===
*trid: [[Protocols/MSNP/General/Commands#Transaction_IDs|Transaction ID]]
*rec_ver: Recommended client version, "1.0.0000" for unrecognised clients
*rec_ver2: Always identical to rec_ver

== Other notes ==
Like with any other command, the server will reply to a CVR command with a CVR reply. For some reason, though, the official client would be just as happy if you replaced CVR with CVQ in the reply.
