Leftovers?

[peteut]

Indeed, sorry about that. Forgot to do a branch. Should be fixed now.

Does this change keep backward compatibility?

change keep backward compatibility?

I'm new to mermaid-js and have to check the changelog regarding syntax changes.

Thanks @peteut I just figured out I accidentally used flowchart (https://mermaid-js.github.io/mermaid/#/flowchart) instead of statediagram. I guess the first line graph TD confused me 🤔

change keep backward compatibility?

It should be fine because we use another (and now right) chart type

[peteut]

I did run into a syntax error with the graph TD solution when using underlines within identifiers (events or states).
