Proposed documentation enhancement

In the "Describe your changes in the changelog" section,
For example, for an enhancement PR with number 12345, the changelog entry should be added as a new file doc/changes/devel/12345.enhancement.rst.

But Enhancement is not acknowledged as change type. This is slightly confusing to a new contributor. I would like to change this to newfeature
