Hi,
Based on additional feature requests and review comments, I've rewritten
almost the entire GF 3.1 Upgrade Guide. Old content has been reworked,
many new topics have been added, and the "Upgrading..." chapter has been
totally redesigned. Please take a look at this latest guide and give me
your review comments as soon as possible.

Thanks very much,
