[4.6.0] - 2020-05-26

Added

• Added maxCachedUsers option to LDConfig. You can now specify the number of users to be cached or use -1 for unlimited cached users.

Fixed

• FlagStore properly synchronizes reads and writes to prevent a potential race condition.

[4.5.0] - 2020-03-26

Changed

• Updated SDK code to build, run, and test on Xcode 11.4.

[4.4.1] - 2020-02-04

Changed

• The SDK will now retry an event send once when the initial request fails.

[4.4.0] - 2019-12-19

Added

• Added startCompleteWhenFlagsReceived function which contains modified completion behavior. This new function's completion will only return after flag values are received. Previously the start completion returned when the SDK went online.
• The SDK now specifies a uniquely identifiable request header when sending events to LaunchDarkly to ensure that events are only processed once, even if the SDK sends them two times due to a failed initial attempt.

[4.3.2] - 2019-12-19

Fixed

• Flag change listeners will now be called when a flag value changes but a variation number does not change. Previously, flag listeners were not called when a value assigned to a variation was manually edited in the dashboard or via the API.

[4.3.1] - 2019-12-12

Changed

• Updated to ios-eventsource version 4.1.0. This negates the need to use_frameworks! when using the React Native SDK. This change does not affect the iOS SDK.

[4.3.0] - 2019-12-3

Added

• Implemented variationDetail which returns an Evaluation Reason giving developers greater insight into why a value was returned.
• Added support for the latest Experimentation features allowing increased value from A/B/n testing. The track method now supports an additional metricValue parameter.

[4.2.1] - 2019-11-15

Changed

• Updated to ios-eventsource version 4.0.3. This appends a platform name to bundle identifiers. (Thanks, cswelin!)

Fixed

• Comparing two nil objects of type [String: Any]? no longer causes a crash. (#197)

[4.2.0] - 2019-10-25

Added

• The identify function allows a completion to be called after a user is updated.
• The Connection Status API allows greater introspection into the current LaunchDarkly connection and the health of local flags.
  • This feature adds a new class called ConnectionInformation that contains properties that keep track of the current connection mode e.g. streaming or polling, when and how a connection failed, and the last time flags were updated. This class can be accessed from LDClient.shared.getConnectionInformation.
  • Additionally, a new observer function called observeCurrentConnectionMode allows your application to listen to changes in the SDK's connection to LaunchDarkly.

Changed

• The user property is now deprecated in favor of the identify function.

[4.1.2] - 2019-07-11

Fixed

• WatchKit is now conditionally imported in WatchOS only to fix an error in Xcode 11.
• Comparing two nil objects of type [String: Any]? no longer causes a crash.
