+Features
+* Improved logging by @dweindl in https://github.com/AMICI-dev/AMICI/pull/1907
+
+  For Python: Don't print messages to stdout, but collect them in ReturnData
+  and forward them to python logging, making it easier to filter specific
+  messages or to disable output completely. Messages are also available via
+  `ReturnData.messages`.
+
+  **breaking change for C++ interface**:
+  Messages aren't printed to stdout by default, but are collected in
+  `ReturnData`. The user has to decide what to do with them.
