Installed ZCM 11.2 on SLES 11.1...Brand new install (ie not a upgrade)

After going thru the install and configuring update info and telling the server to check for updates I got 2 available updates:
1) March 2012 PRU update (I understand this one)
2) Agent Update 1 for Zenworks 11.1

Why would a update for a agent for ZCM 11.1 come down with a brand new 11.2 server ??
Should it be downloaded ??

Thanks in advance
