I am currently collecting some PRs here and would love to see this landing. Want to take a look?

Ok, so my work now moved to this repo. I will have a look into this PR asap since it's important for me to land it.
In the meantime it would be awesome if you could squash all your commits into one which describes the work you've done.

Thank you so much.

Thanks for this again!

I've now implemented a way to update the changelog by not running other tasks but by updating the changelog itself. Please see 9ffe8d3. I think this is more useful.

The solution you implemented is not just the changelog task but another solution which gives implementors the possibility to run all tasks they want.
Please feel free to open another PR which does these callback tasks more generic if you are interested. Please also have a look at #59.

If you think the solution I provide is not great please let me know.
