This release is fully Perl 5.10 compatible (and lifts some of the restrictions present in older Perl releases). Coroutine memory size has been reduced to less than 3kb including stacks on 32-bit machines. A new event backend, Coro::EV, is available. Coro::Util can take advantage of EV::ADNS for asynchronous DNS resolution. Coro::Debug allows backtraces, runtime tracing, code injection, and more, and offers an interactive shell that works out of the box in event-based programs, even for non-coroutine programs. Coro::BDB supports async Berkeley DB access. Many bugs have been fixed.
