+### Changes in Viper Language
+
+- unfold, fold, unfolding only strictly positive (which also fixes an unsoundness) ([Silver#444](https://github.com/viperproject/silver/pull/444))
+- no longer using Int as default for unconstrained type args inside domain ([Silver#758](https://github.com/viperproject/silver/pull/758))
+- opaque annotation ([Silicon#767](https://github.com/viperproject/silicon/pull/767)) and ([Carbon#474](https://github.com/viperproject/carbon/pull/474))
+
+### API changes:
+- error and reason sealed ([Silver#749](https://github.com/viperproject/silver/pull/749))
+- re-designed Parse AST?
+
+### Changes in plugins:
+- smoke detection plugin ([Silver#762](https://github.com/viperproject/silver/pull/762))
+- auto-generating well-foundedness axioms for adt types ([Silver#743](https://github.com/viperproject/silver/pull/743))
+- incomplete termination plugin fix ([Silver#754](https://github.com/viperproject/silver/pull/754))

+
+### Other Viper-level improvements:
+- fixing incompleteness where domain axioms were not instantiated properly ([Silver#???](https://github.com/viperproject/silver/pull/???))
+- improved parsing and type checking errors ([Silver#723](https://github.com/viperproject/silver/pull/723))
+- trigger inference improvements:
+  - proper treatment of let-expressions when generating triggers ([Silver#753](https://github.com/viperproject/silver/pull/753))
+  - trigger inference no longer incorrectly omits old ([Silver#747](https://github.com/viperproject/silver/pull/747))
