4.0.0

• Added: Support for Pebble 2.
• Added: New superclass PBSemanticVersion. PBFirmwareVersion is now a subtype of PBSemanticVersion.
• Added: New values SendTextSupported, NotificationsFilteringSupported, UnreadCoredumpSupport, and WeatherApp2 in PBRemoteProtocolCapabilitiesFlags.
• Added: PBPebbleKitLogging type to customize the logging callback used by PebbleKit and the log level.
• Changed: Remove outdated documentation for PBWatch. Improved documentation about -[PBWatch friendlyDescription].
• Changed: Clean up the PBDataLoggingService header. Use modern type names and improve nullability annotations.
• Changed: Added nullability annotations to NSDictionary+Pebble.h. Deprecated old methods without pb_ prefix and added alternative methods with pb_ prefixes instead.
• Changed: Added nullability annotations to NSNumber+stdint.h. Deprecated old methods without pb_ prefix and added alternative methods with pb_.
• Changed: Deprecated method for setting the default log level in PBPebbleCentral in favor of the new methods in PBPebbleKitLogging.
• Changed: Communication with the watches (both through Classic and through LE) will not longer happen in the main thread. The callbacks will still be invoked in the main thread, and many methods are still documented as needed to be called from the main thread. We might lift those restrictions in the future, but they are still in place.
• Changed: Clean up the Sports API and document and improve PBSportUpdate helper object.
• Fixed: PebbleKit-Static uses the right header paths for Cocoapods.
• Fixed: PebbleKit-Static is stripped of its debugs symbols, which should avoid printing some warnings.
• Fixed: Golf and Sports do not need to add their UUID manually before using their APIs.
• Fixed: Added correct nullability annotations for PBWatch (Golf) and PBWatch (Sports).
• Fixed: Signature of appMessagesPushUpdate:withUUID:onSent: no longer declares a non-nullable NSError * named __nullableerror.
• Fixed: Race condition that was making the communication with watch impossible.
• Fixed: -[PBFirmwareVersion compare:] was reporting the wrong results for firmwares released far in the future.
• Fixed: Connecting through Bluetooth LE should be more reliable.
• Fixed: Don’t try connecting with devices that are not Pebble.
• Fixed: Don’t try connecting with Pebble devices that are connected to other mobile devices.
• Fixed: Added correct nullability annotation for PBVersionInfoCompletionBlock.
• Fixed: Avoid crash while reconnecting to Bluetooth LE devices.
• Deprecated: PBFirmwareVersion os, major, and minor, as well as the convenience initializer firmwareVersionWithOS:major:minor:suffix:commitHash:timestamp: has been deprecated. Use instead majorVersion, minorVersion, revisionVersion and firmwareVersionWithMajor:minor:revision:suffix:commitHash:timestamp:.
• Removed: Support for Bluetooth Classic communication. Only Bluetooth LE is available. All devices in 3.x or later should be able to use Bluetooth LE, including the original Pebble and Pebble Steel. This should make communication from several third party apps a lot better.
