As always happens with new versions of operational systems, some important functionalies of macOS Sierra are buggy: binary data is stored incorrectly in the defaults.
This affects the storing of non-integer parameters in FastRawViewer.
To work around this issue, we are releasing FastRawViewer 1.3.5.
This release also addressed some minor problems, so the Windows version has also been updated.
As usual this update is free for those who has already had previous versions of FastRawViewer.
