Configuration for ChangeLog Step so that Merges are included. (Or at least squashed merges)

Description of the feature request

A change was made a while ago to exclude merges from the change log. I would like an option to have this feature put back. We are using BitBucket as for our repo, and are using a feature branch / PR way of working. We have recently decided that when we merge back into our main branch we should squash all the commits.

This has had the effect of the changelog that gets generated being empty as it is ignoring merge commits and this is classes as a merge commit.

Use case / for what or how I would use it

Either include squashes (if they can be identified easily) Or have an option to include merge commits instead of excluding them all the time.
