Main differences between XF1.5 and XF2.0

[kingjavo]

Can someone please help me understand what the differences are between these two versions? I'm thinking of upgrading, but wanted to understand the benefits before upgrading my license.

- XF 1 add-ons / themes will not work with XF 2. You'll need to have them ported over.
- XF 2 introduces some new stuff but I think the major features are coming in XF 2.1. See this thread for more details.
