Status Quo

towncrier build will generate the following example changelog entry

<!-- towncrier release notes start -->

## <New Release>

### Changed

- Something changed


## Old Release

Notice how there are 2 newlines between Something changed and ## Old Release.

It may be useful in some contexts to customize it. For instance I'm on a team that prefers not to have the second newline between releases.

I think the most flexible solution would be to add a configuration field called something like release_separator. It could have a default value of either \n or \n\n depending on what we consider as an integral part of one release section.
