Hi Don,
In a previous UVM forum post, Tom Alsop, the co-chair of Accellera VIP-TSC addresses your concern about the early adopter vs.. the 1.0 version (see http://www.uvmworld.org/forums/showthread.php?69-Backward-Compatibility-of-UVM-1.0-from-UVM-1.0EA). Currently, we are discussing in Accellera complementary capabilities that do not change the high-level methodology nor contradict the library tips in the book. The new features being considered for the 1.0 release are useful but incremental to the core methodology which is already in the 1.0 EA release.
The book (that cost less than a $100) is relevant both in terms of methodology and the library. As an author of the book, I hope that you will find it very useful.
Cheers,
-- Sharon
