# How to get old message formatting in version 11?

Version 11 uses a new-style message formatting.

The new style has useful features, and it is usually desirable. However, when saved in a notebook, it doesn't display correctly in older versions of Mathematica. If we use version 11 to write documentation for a package that is also compatible with older versions, we cannot include new-style messages in the notebook.

How can we turn off this new message formatting?
