Moving from Atom 0.3 to 1.0: "

Niels
Leenheer: Many people will automatically move to Atom 1.0
when they upgrade their weblog software, or when large weblog
providers such as Blogger update their software. The rest of us,
who are going to change our feeds manually are going to run into a
number of differences between Atom 0.3 and Atom 1.0.  Below I
will highlight some of the main changes.

Thanks!
