Yes, we are making steady progress in the development of OLab4.
High on our list is a greatly improved authoring interface, but this will take time to get right. However, some teams are keen to make use of the new features of OLab4 right away.
To facilitate this, we are working on a converter for OpenLabyrinth v3 cases. We estimate that for many current cases, very little additional work will be needed after conversion.
But there are a number of functions and features in OLab3 that are so rarely used that we have decided not to support them in OLab4. For a list of what is going to be deprecated, please refer to the Technical Forum and look for this topic (or use the link below to jump straight there)…
If you are concerned that this might create problems with your existing OLab3 cases and want to use them in OLab4, contact us through the Forum.
