Unity 2020.2 beta is here and given the released number of releases that Unity are going to do annually, that makes this a more significant release than in the past. This beta release includes several system level and quality of life improvements including:
Support for C# 8
Dark Mode IDE support (this was actually added to previous versions as well)
C# compiler and IL2CPP compiler improvements
EIP, or Editor Iteration Profiler, to help identify bottlenecks during domain reloads
Unity Safe Mode for troubleshooting script errors on startup
Be sure to check out the complete release notes for more details on the changes in Unity 2020.2. You can also learn more about the release in the video below, including a small rant about one of the biggest problems facing Unity these days… fragmentation and stability.
