Folks, we've only so many hours in a working day and many projects in active development at the moment. In addition, while on the surface it appears to be simply a matter of "pointing" the installer to yet another sim version, there are some significant internal changes to the core that some of our .dll modules will need to be updated and re-compiled to work with P3D v3. This of course will require extensive re-coding, compiling and testing.
More significant is deciding whether to simply accept the status-quo or adapt our strategy to use the new add-on system that L-M is asking us to use.
