 ## [Unreleased]
 
+- Add unreleased items here.
+
+## [1.2.0] - 2018-03-01
+
 - Update build to test with Go 1.9, drop support for 1.7 since `dep` now
   requires Go 1.8+. Go 1.7 users can still use this library but must manage
   their own dependencies.
 - Add `WithRate(rate float)` to the DataDog client to limit traffic sent to
   the `dogstatsd` daemon. The set rate will be applied to all calls made
   with the returned `Client`.
+- Automatically assign tags to events.
