Will Atahualpa 3.7.7 work with the latest Wordpress (3.3.2)?

I'm running a really old version of Wordpress (2.8.4) with a really old version of Atahualpa (3.3.2). I want to bite the bullet and upgrade my Wordpress so I can install a plug-in that only works with the new version. But Atahualpa is working fine for me. I have it configured exactly as I want, and I don't want to make any changes. I really don't want to upgrade and risk breaking my settings. On the other hand, I REALLY don't want to upgrade Wordpress and break my entire blog because the theme I'm using is incompatible with the latest version of Wordpress. So I really need to know...

Is Atahualpa 3.3.2 compatible with Wordpress 3.7.7 (latest version)? It looks like the changes have all been enhancements and bug fixes that don't affect me, but I can't tell for sure.

Thanks in advance.
