Just like everybody else, I never read the readme or other documentation files so I dug straight into the class code and examples. Soon after I realized that the new changes were not that bad, so instead of the usual 5 lines of code, I shortened it up to only one. I stopped worrying about parsing XML or JSON, converting them to objects, and I stopped typing in the full address for Twitter API calls. Abraham did all that for us.
It makes it simpler to use, but can break backwards compatibility, so watch out for that if you're using Abraham's library. If you're interested who's using the class, check out this page on his github wiki.
