• Fixes an issue where Optimal Cycling won’t compile on GPUs by being more strict with the OpenCL syntax.
• Optimal Cycling can now cache more than one compiled version of the OpenCL code to reduce waiting time if you like to switch back and forth between CPU and GPU.
• Added an option to use exponential smoothing with the generalized mean power metric instead of with regular rolling average smoothing.
• The data file format has been updated to version 2.1. Older file formats will automatically be converted to the new one.
