| Changes from 1.0 to 2.0 |
| ======================= |
| |
| You should expect to see noticeable changes in the characteristics of the |
| following benchmarks: bodytrack, canneal, dedup and x264. |
| |
| It is possible that the characteristics of all other programs that were updated |
| have changed, too. The only guarantee for identical characteristics is an |
| identical source code (assuming everything else also remains the same). |
