Out of beta in 3, 2, 1! 🎉

Added:

• Enforcing Core Location Services permissions — in order to report enter/exit events, your apps need either WhenInUse (to work when the app is active) or Always (to work in background as well) permission.
• Proximity SDK now supports telemetry reporting to Estimote Cloud.

Changed:

• Errors related to the SDK initialization, zone observation, and Location Services are more descriptive.
• EPXProximityZoneContext is not a protocol anymore, but a class (so you can use it nicely within your Swift apps).
• Swift classes have no EPX prefixes.
• Parameters and naming in ProximityZone's init and event callbacks now follows a clearer convention, and is consistent with the Android version.

Removed:

• EPXDeviceAttachment class.
• DeskObservers sample apps - from now on please use app templates as a reference instead.
