Expected Behavior:
No crashes.
@weibel recommend using our 4.0.0.beta branch which replaces the file-based archiving system with SQLite. It also removes all of the Messages & Experiments functionality, which will be deprecated on Dec 31. Other than that, it is in parity with the current release. After the M&E deprecation it will be promoted from beta to the main release version.
@jaredmixpanel Thanks for getting back to me so quickly. I want to avoid rolling out a beta version of the SDK just before the holiday season. After all it is called a beta for a reason. However I'll be happy to look into it once the new version has been out of beta for a little while.
