yes you are right, we released an update about 20 hours ago and updated to V-Play 2.6.0. The blog release will follow on Tuesday, you can already now see the changelog here.
In the latest release, we updated to the newest Box2D version and added a lot of new functionality. Also, we improved the API from previous versions 2.5.2 and below. If you have existing Box2D code in your project, please follow the Box2D Upgrade Guide.
Please make sure to follow the upgrade guide and if you were using one of the features that got changed, change them to the latest API. We also updated all our tutorials, Box2D examples and demo games to match the new API, so you can also have a look there. Sorry for the temp inconvenience, but in the long run the new API is better and simpler to use which led to the update.
