WARNING: I accidentally broke c++ ABI compatibility between 2.1.0 and 2.2.0. This is fixed here. There will likely be a 2.2.1 patch release. If you are packaging this software for distribution, you might want to skip packaging this version or make sure the above patch is applied in your build. For all the wrapper code, this has no impact whatsoever. Please join the discussion if you have comments regarding the situation.
Major Changes
This release is mostly about the Python, Android and iOS wrappers. The latter 2 have changed considerably to have an API that is more in line with each other and with the core c++ library. The changes will most likely break existing app code but set a proper foundation for the future.
