Privacy Browser 3.6.1 was released with fix for a bug that caused View Source to crash on release builds. Because most of my devices are running debug builds it took a while before I was able to reproduce the bug. The root cause was that ProGuard, which removed unneeded methods in release builds to make them smaller, was incorrectly removing the ViewModelFactory used by View Source which was introduced with the switch to the Day/Night theme.

This is the first time I have had a bug that only manifested in release builds. Looks like there is one more thing I am going to have to test before each release.
