 # Change Log
 
+## 4.0.0 (2024-10-03)
+
+### Breaking Changes
+
+- `isUniqueIdentifier` parameter has been removed from methods [`flush`][flush], [`getRemoteVisitorData`][getremotevisitordata] and [`trackConversion`][trackconversion]
+- Previously deprecated method [`onConfigurationUpdate`][onconfigurationupdate] has been removed from SDKs. Use [`onEvent`][onevent] method with `EventType.ConfigurationUpdate` to achieve the same effect.
+- Previously deprecated field [`domain`][domain] of `SDKConfiguration` has been removed from SDKs. Use [`cookieDomain`][domain] field of `SDKConfiguration` instead.
+- Parameter `text` of `KameleoonResponseType` used in custom [`requester`][requester] implementation is now mandatory, for the vast majority of implementations like `fetch`, `axios` or `node-fetch` it won't require any changes.
+- Method [`initialize`][initialize] no more accepts `useCache` boolean parameter. Using storage cached client configuration on failed configuration request is now default behavior.
+
+### Features
+
+- Added new [`UniqueIdentifier`][uniqueidentifier] data to be used instead of removed `isUniqueIdentifier` parameters in some methods
+- Added new [`SDKConfiguration`][sdkconfiguration] parameter `trackingInterval` to set the interval between SDK tracking network requests in _milliseconds_, default value is 1000, which is also maximum interval, minimum value is 100
+- `FeatureVariableType` returned from the methods obtaining feature flag variables can now have two new `VariableType`s - `VariableType.JS` containing a `string` of JavaScript code and `VariableType.CSS` containing a string with CSS code
+
+### Patch Changes
+
+- [`getEngineTrackingCode`][getenginetrackingcode] method now correctly sets `triggerExperiment` parameter based on variable types
+- Updated dependencies
