@@ -8,6 +8,11 @@ Version 1.1.x
 -------------
 Long run average computation via ValueIteration, LP based MDP model checking, parametric model checking has an own binary
 
+### Version 1.1.1
+- c++ api changes: Building model takes BuilderOptions instead of extended list of Booleans, does not depend on settings anymore.
+- storm-cli-utilities now contains cli related stuff, instead of storm-lib
+- storm-pars: support for welldefinedness constraints in mdps.
+
 ### Version 1.1.0 (2017/8)
 
 - Support for long-run average rewards on MDPs and Markov automata using a value-iteration based approach.
