 ## Change Log
 
-### 2.2.5
-
+### 2.3.0
+
+This release contains a significant change - Simulators will not be
+automatically be relaunched whenever
+`Calabash::Cucumber::Launcher#relaunch` is called.  Instead, run-loop
+will try to keep the simulator running as long as it appears to be
+health.  This change is only for DeviceAgent test runs.  Tests that use
+UIAutomation will continue to relaunch the simulator.
+
+If you are on macOS Sierra or using Xcode >= 8.0, you are running
+against DeviceAgent.  UIAutomation is only used on El Cap with Xcode <
+8.0 and iOS < 10.
+
+If your tests need the simulator to relaunch every time
+`Launcher#relaunch` is called, you can pass the new `:relaunch_simulator =>
+true` option.  This option is provided for backward compatibility.
