Hi,

I understand NARUSE-san's comment (feature of 2.0 is matter) and
Urabe-san's comment (needs a lot of time to discuss 2.0 features).

My suggestion is:
- release 1.9.4, as an extension of 1.9.3 by 2012
- during making 1.9.4, discuss 2.0 features (and maintenance policies)
- after 1.9.4, split 1.9 branch and start 2.0 on trunk

I think 2.0 is good point to throw away some compatibility issues (e.g.
C APIs).  We need more time to discuss.

Regards,
Koichi
