Dev DSPRs, which line to take to the new Ruby version?

[Tronic]

definitely not a question that you have made ​​other people,
would like to know how developers will adjust with new releases of Ruby.
For example, today we are the official Ruby 2.0.0-p0
where changes have been made on both the interpreter that the compiler.
for me the most interesting things are the ability to save and load directly into bytecode format, and a new threading system where only one area, it is locked if timeout is reached, but the rest of the code works correctly, I think this one in particular solve the problem which has now FS, shutting down the code if you reach high demands, or if it is the timeout is reached.

so expect news
thanks DSPRs Developers
