         * Version 0.11.0 released
         =========================
 
         Correct model gradient computation
+        Increased number of integration iterations for energy dispersion (#1472)
         Add GOptimizerLM::logger() method, logger constructor takes pointer (#1471)
         Replaced fixed precision integration by fixed iterations (#1466)
         Implement rejection method for skymap Monte Carlo (#1465)

 likelihood function is smooth.
 
+The number of integration iterations for the energy dispersion was changed from
+4 to 5 to make it compatible with the default integration order.
