Hi,

as I could not find any reference in recent postings, please allow for  
this  
question:

is there any web site that lists planned and current changes in the C  
Ruby  
runtime for Ruby 1.9 and onwards?

I’m especially interested in threading support, but also in other  
changes  
that might significantly influence the behavior of ruby programs, but  
are  
not directly reflected in the core API documentation.

I know that programs are supposed to be largely runtime agnostic, but  
some  
limits and possibilities of the runtime might still influence the way  
certain features can or should be used.

Thanks  
Rainer Frey
