The Artistic 2.0 notes <http://www.perlfoundation.org/legal/licenses/ 
artistic-2_0-notes.html> walk you through the new license, but they  
don't specifically highlight the changes. This will make a nice  
addition to the FAQ.

Overall, the terms of the Artistic 2 are the same as the Artistic 1,  
though the language has been polished and reorganized to be more  
readable and more legally precise. The significant additions are  
sections 4(c)(ii) and 13.

Section 4(c)(ii) is what we call the "relicensing" clause, because it  
allows you to take a package you received under the Artistic License  
and use it under the terms of a copyleft license such as GPL, MPL, or  
Apache. This is a significant advantage for downstream licensing  
compatibility. If you want to include an Artistic licensed package  
in, for example, an MPL package, you can relicense the Artistic  
package under the MPL to include it in your package.

Section 13 minimizes the likelihood of patent litigation. We want to  
do what we can to promote our users' freedoms, even though some  
people might try to take freedoms away from them by using software  
patents in unscrupulous ways.
