Your answer should be parseable with JSON.parse() without modifying anything.

Here is the structure of the JSON you should return:

You are building a changelog file for the projext.
Omit commits and versions that lack relevant changes.

You are given

Only return the changelog file, so it can be written directly to changelog.md

For the latest version, that is not yet part of the commit messages, add a placeholder entry that uses {{nextVersion}} and {{nextVersionMessage}} as variables to filled later.
Only output newer versions and their changes compared to ones already mentioned. We take of appending your output later.
If there is no previous changelog file, generate a complete changelog from commit messages with heading and everything + the placeholder section mentioned above.
