Markdown in WordPress 3.2?

I found the question Create posts using markdown? about using Markdown on WordPress, however the plugins referred to haven’t all been upgraded to WordPress 3.0 or higher.

Since I happen to be a bit pedantic about using updated plugin, what options are available to integrate Markdown for both editing and displaying on a WordPress 3.0 or higher setup?

What about Markdown on Save by WordPress lead dev Mark Jaquith?

Allows you to compose content in Markdown on a per-item basis. The
markdown version is stored separately, so you can deactivate this
plugin any time.

Compatible up to 3.3 attow.
