At present these are just warnings that the specific plugins were not designed for CB 2.0 and may or may not work.
We have been working on including a legacy layer for our API usage to make it so that most plugins even with warnings will work ok until new releases happen that will take care of the warning.
See list of known plugin issues on CB 2.0 here:
