+## [2.10.0] - 2018-02-01
+### Added
+- Support for specifying [private user attributes](https://docs.launchdarkly.com/docs/private-user-attributes) in order to prevent user attributes from being sent in analytics events back to LaunchDarkly. See the `allUserAttributesPrivate` and `privateUserAttributes` properties of `LDConfig` as well as the `privateAttributes` property of `LDUserBuilder`.
+
 ## [2.9.1] - 2017-12-05
 ### Fixed
 - Carthage builds no longer crash due to a missing DarklyEventSource library.
