Log Message:
py-structlog: updated to 19.1.0

19.1.0:

Backward-incompatible changes:
- As announced in 18.1.0, pip install -e .[dev] now installs all development \ 
dependencies.
  Sorry for the inconveniences this undoubtedly will cause!

Changes:
- structlog.ReturnLogger and structlog.PrintLogger now have a fatal() log method.
- Under certain (rather unclear) circumstances, the frame extraction could throw \ 
an SystemError: error return without exception set.
  A workaround has been added.
- structlog now tolerates passing through dict\ s to stdlib logging.
