Releases · configcat/java-sdk

Added

ConfigCatClient.get() factory method that produces a single instance / SDK key.
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.
getValueDetails() / getValueDetailsAsync() methods to retrieve evaluation details along with the feature flag / setting value.
getAllValueDetails() / getAllValueDetailsAsync() methods to retrieve the detailed values of all feature flags or settings.
onCleintReady() / onBeforeClientClose() / onConfigChanged(Map<String, Setting>) / onFlagEvaluated(EvaluationDetails) / onError(String) hooks. Subscription is possible on client initialization options and on the hooks property of ConfigCatClient.
setDefaultUser(user) / clearDefaultUser() methods to set / remove a default user object used when there's no user passed to getValue[Async]() / getValueDetails[Async]() / getAllValues[Async]() / getAllValueDetails[Async]() methods.

Changed

Client initialization options were moved to a Options object that can be passed with a Consumer to the new ConfigCatClient.get() factory method.
ConfigCatClient can be explicitly closed via client.close() and ConfigCatClient.closeAll() methods.
forceRefresh() method now returns with a result object to indicate whether the refresh succeeded or not.
autoPollRateInSeconds lower limit changed to 1 second.
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.
Fetch logic handles 403 response status and update cached fetchTime in case of 304 403 and 404 response status.

Removed

ConfigCatClient(String sdkKey) public constructor.
asyncRefresh parameter of PollingModes.lazyLoad().
getVariationId(), getVariationIdAsync(), getAllVariationIds(), getAllVariationIdsAsync() removed in favour of getValueDetails(), getAllValueDetails()
configurationChangeListener parameter of PollingModes.autoPoll(). It was replaced by the onConfigChanged() hook.
