4.1.0 - Property Obfuscation

Instance, class and global properties will now be obfuscated, with the exception of properties under types that inherit from Codable and classes exposed to Objective-C. For more information, check the limitations document.

Although we have lots of tests checking if property obfuscation is working correctly, we're still not certain that we covered all edge cases. If you don't feel like gambling on this, it might be better to use version 4.0.3.
