Features

• Improved logging by @dweindl in #1907

  For Python: Don't print messages to stdout, but collect them in ReturnData

  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.
