the documentation on how to update the client's code upon such createFromSVG error is here:
https://github.com/juce-framework/JUCE/blob/master/BREAKING_CHANGES.md#change-1

though I am not sure about the remaining two other.

Thanks, fixed here: c80f091

Note that the error you're seeing is in one of the example projects. It shouldn't affect your ability to build other JUCE-based projects, including your own existing projects.
