This section details on the original issue you should resolve

<issue_title>Release notes / changelog does not display commit type title</issue_title>
<issue_description>I am in the process of testing this config out and noticed that the changelog shows the commit type in lowercase rather than the formatted title value set in types.

It seems that due to the commit here:

It looks like you were changing the way it works, but the commit.type is not set to the new groupType value. Your own changelog is showing this issue for the last commit or two.</issue_description>
