Is there a way, using fastlane's action changelog_from_git_commits to generate change log based on the commits between last version uploaded and current version + save it to the CHANGELOG.MD file? Each uploaded version would serve as a header.
Build number for each upload is "fetched" based on number of commits from the repository (via via run script in Xcode).
So it would look something like:
1.2.0 (186)
- Commit 1
- Commit 2
- Commit 3
- Commit 4
- Commit 5
1.2.0 (127)
- Commit 1
- Commit 2
- Commit 3
- Commit 4
- Commit 5
. . . . .
