+dynare (4.0.0) UNRELEASED; urgency=low
+
+  * First official release in the 4.0 series
+  * New functions {load,save}_params_and_steady_state
+  * Fixed bug with forecasting with exogenous deterministic variables
+  * BVAR à la Sims:
+    - no longer remove explosive models when drawing from the posterior
+    - forecasting now reports median path instead of mean path
+  * Fixed bug and improve performance in diffuse filter/smoother
+  * Fixed crash of estimation in some cases
