Hi, Erik Thank you. And this is my plan: I've fixed lots of bugs since 0.5.0, and I want to release 0.5.1 once the CLISP / FFI work is done. And once 0.5.1 is out, I'll backport all changes on branch 0.5.x to trunk and start working on SOCKET-OPTION API on trunk, and once it's done again, consider this is new added API, I want to release 0.6.0, but the exact release date is unknown at this time. --binghe 在 2011-3-30，03:50， Erik Huelsmann 写道：

Hi Chun,

Nice work (and great activity!).

Just a remark from personal experience: Don't forget to backport to trunk when you're working directly on the branch.

Bye,

Erik.
