Hi,
I just wanted to thank you for your hard work, but also tell you that I agree with the general feeling that making a regular “stable” version from time to time would be a really great thing.
For example, look at how Canonical makes regular Ubuntu updates, but has a LTS (Long-Term Support) every 2 years.
Basically, UE4 on OS X is super unstable. I can expect a crash roughly every 30 minutes.
