2.2.1 - 2022-10-17

2.0.2 - 2022-09-28

2.0.1 - 2022-09-27

Fixed

• Static analyzer warnings.

2.0.0 - 2022-09-27

Added

• setDefaultUser(user) / clearDefaultUser() methods to set / remove a default user object used when there's no user passed to getValue() / getValueDetails() / getAllValues() / getAllVariationIds() methods.
• setOffline() / setOnline() methods to indicate whether the SDK is allowed to make HTTP calls or not. In 'offline' mode the SDK works from the cache only.
• onClientReady() / onConfigChanged(Map<string, Setting>) / onFlagEvaluated(EvaluationDetails) / onError(String) hooks. Subscription is possible on client initialization options and on the hooks property of ConfigCatClient.
• getValueDetails() method to retrieve evaluation details along with the feature flag / setting value. It returns the same details that is passed to onFlagEvaluated(EvaluationDetails) on each evaluation.

Changed

• The static close() method was split to an instance level close() method which closes the given ConfigCatClient and to a static closeAll() method which closes all instantiated client instances.
• The forceRefresh() method now returns with a result object that indicates whether the refresh succeeded or not.
• The TTL of lazyLoad and interval of autoPoll is compared against a cached fetchTime, which allows the SDK not necessarily download a new config.json at each application restart.

Removed

• The onConfigChanged() hook parameter of PollingModes.autoPoll. It was replaced by the newly introduced onConfigChanged(Map<string, Setting>) hook function which is invoked with each polling mode.

1.1.0 - 2022-08-16

Changed

• Replaced the refresh policies construction with a single config service that takes care of the different polling mechanisms, caching, and the synchronization of HTTP requests.

1.0.2 - 2022-08-09

Fixed

• Send the correct SDK version in HTTP header.

1.0.1 - 2022-08-04

Fixed

• When the dataGovernance parameter wasn't in match with the remote setting, it could have happened that the fetcher downloaded the correct config.json multiple times.
