As part of our continued effort to make our releases more useful,
we will be adding our CHANGELOG entries to the GitHub Release.
To make this process smooth, we are going to change things a little:
1. All new changelog entries when submitting a PR for an upcoming
release will now need to get added to CHANGELOG_PENDING.md
This is the source of information for what will be delivered in the
release.
2. When a release is being made, the entries from CHANGELOG_PENDING
will be copied to a new version and dated section in CHANGLOG to
mark the release
3. The GH tags will continue as normal and Goreleaser will copy
the changelog entries to the release section in GH
