[Q] 2.2 Code Highlight

I have installed a dozen code highlight plugins today, both on my local and live servers, and non of them seem to work with 2.2

Am I losing my mind or has there been so many changes to 2.2 that all code highlighting plugins don’t work?

Does anyone else have this problem?
Should I revert back to 2.0?

I have an actionscript blog site in which a lot of code needs to be displayed for my blog to be affected.

Thanks.
