A lot of new features going on, like openomy based file uploading and links that work like simple rst directives:
.. openomy:: my-file.ext
And you should get a link to the file, stored in the 1GB the openomy guys kindly provide.
Also, you can actually see how the test site looks at //ralsina.me/weblog (using the exact same data as this one).
I actually upload almost every change I do, so it breaks often ;-)
