 ## Version History
 
-#### Development
+#### v3.0.1 (2017-09-13)
 
 * Set Swift version back to Swift 3.2. The new `KeyPath` stuff is usable from 3.2 so there's no reason to require 4. PMVKObserver will still compile with Swift 3.1, but the `KeyPath` APIs won't be available unless compiling with Swift 3.2.
