[trinidad] Status of trinidad 2.0?

[Me Self]

Im starting a new JSF project and must decide whether to go with a
stabile 1.2 impl or if I should risk it and use 2.0 beta. Im
considering 2.0 because the app will be used by powerusers - they need
all the clientside javascript speedups I can provide. So I would like
to hear your opinions - will it be too much trouble going with the
beta now (project deadline is in august)? Do I risk that features that
were working in 1.2 are broken in 2.0 beta?
