Mars.2 was successfully released on Friday, February 26st. “Mars.2” is the second “service release” for Mars (former SR2). We updated the EclipseSource Oomph Profile accordingly, so, if you use our profile, you just need to restart your Eclipse IDE, and all updates will be applied for you.
If you are running multiple instances, please close all except the one you restart. The update will take a while and run in the background, you can observe the status in the progress view on the bottom of your IDE. Once the update is finished, you need to restart again, the update should be completed and you should see the new splash screen. Please see here to learn how to use the EclipseSource Oomph profile.
