At the bottom of the page it says:
SolarWinds Orion Core 2011.1.0 SP1, APM 4.0.2 SP4, NMP 10.1.2 SP1, IVIM 1.1.1
Is APM 4.2 the same as 4.0.2 ?
4.0.2 is different to 4.2 - APM 4.2.0 is the latest version, and has a lot of new features over 4.0.2 - http://www.solarwinds.com/documentation/apm/docs/ReleaseNotes/releaseNotes.htm
NPM is currently on 10.1.3 so you're a minor revision behind there as well - http://www.solarwinds.com/documentation/orion/docs/ReleaseNotes/releaseNotes.htm(note: NPM 10.2 is at Release Candidate stage, so you could also use that or wait for the general release)
