If you have received an email for the SONAR 2017.02 release and cannot locate it, that's because the SONAR 2017.02 Update is current only available as an Early Access build. This is in order to address some minor last-minute concerns that were discovered by our user community.
We apologize for any confusion in advance that this may have caused.
