Hey,
It looks like the 2.0.0 release does not include the changes mentioned in it. Subsequently the pypi package is also wrong.
https://github.com/MarketSquare/robotframework-seleniumtestability/releases/tag/v2.0.0 & https://pypi.org/project/robotframework-seleniumtestability/
For example: The DesiredCapabilities for Opera is still present.
Could you update it, so it matches the changes?
Thanks!
Best,
Tadej
