the next major update will be V-Play v2.0 which brings Qt 5 support. As we cannot give a precise date when we will be able to release it, we now allow you to access daily builds until this update is released! You can start the V-Play SDK Maintenance Tool and use daily builds now.
Regarding the build issue: this will be fixed tomorrow when we release daily build v1.5.5. Until then, please comment the property binding of showAchievementsHeaderIcon and it will run.
