Hello guys, I've been away from neos for quite a while. I'm trying to upgrade my installation from 1.0.2 to 1.1.2 but this upgrade via composer fails: [Composer\DependencyResolver\SolverProblemsException] Problem 1 - The requested package typo3/buildessentials 2.2.* could not be found. Can somebody help me out here? Thanks, Dominic
