Many thanks for your support!

In theory, we try to maintain long-term stability of PlantUML diagrams.
This project has been started in 2009 and between 2009 and 2022, we did not change the rendering of diagrams.
Some people were complaining that the default visual appearance was ugly, so indeed V1.2022.2 brings some major and breaking changes (with additional support of new CSS feature). Our intention is to keep it stable again for at least the next 10 years.
However, we also want to offer to users the possibility to generate diagrams using the old visual appearance by adding "skin Rose" command.

V1.2022.2 has been released recently (March 2022) and there are issues in the retro-compatibility implementation.
Testing this is really complicated, so it would be nice if you could post here some short text diagram sources that shows regressions.
We'll then try to fix them.
