 ## Master
 
+##### Breaking
+
+* Development pods will no longer be implicitly unlocked. This makes CocoaPods
+  to respect constraints related to dependencies of development pods in the
+  lockfile.
+
+  If you change constraints of a dependency of your development pod, and want to
+  override the locked version, you will have to use
+  `pod update ${DEPENDENCY_NAME}` manually.
