Merge branch 'release/0.3.0' into develop
Attempt #1 and enhancing the plugin

emitted, and then remove them from the dicts to be published.

Not tested yet. Not even sure if it's correct.

TODOs:
- Line #111 needs to be checked. Do we check those values too?
- We could improve the option doc to include what fields one can mention
