4.2.1

[4.2.1] - 2021-06-01

Fixed:

• iOS: Fixed an issue where an exception was thrown when calling LDClient.configure with an optional timeout (#80).
• iOS: Improved consistency with Android for LDClient.isInitialized. Both implementations will now reject the promise if the client has not been configured.
• iOS: Avoid exceptions on iOS when certain methods are called after LDClient.close. (Thanks, andvalsol)! (#75)
• Android: Fixed an issue where the promise for LDClient.configure could be resolved before the client had finished initializing when not providing the optional timeout parameter.
• Android: Fixed an issue where LDClient.allFlags would reject the promise when the client was configured but not yet initialized, rather than resolving with any cached flags.
