Generate Changelog with mixed Commits and Merges

[cebreus]

I'd like to have Changelog separated by type of messages. Filtering to Commits and Merges doesn't make sense to me.

I'd like to show:

💥 Breaking Changes

-   list commits and merges

🚀 New Features

-   list commits and merges

🐛 Bug fix

-   list commits and merges

My merges have message containing "feat: " or "Feature/". Thanks for example.

As of 2.1.0 you can use the commit-list helper for the merges and fixes inside each release. This should let you create a custom template to list things as you describe.
