I have elected to discontinue development of CWAC-Cam2.
There are other libraries for working with the camera, such as Fotoapparat and CameraKit-Android. Trying to maintain camera code is a huge pain in various body parts. If others want to scratch the camera code itch, I am happy for it. In the future, I will spend some time working on testing their code against the devices here in my Secret Mountain Lair™.
The CWAC-Cam2 artifacts will remain available indefinitely. However, I plan no further releases, and I will eventually start turning off parts of the GitHub repository.
If you have any questions about this, reply to this topic.
