• Minor feature enhancements

Release Notes: This release adds an optional ct_return() function by which a thread may return control to the scheduler by a setjmp/longjmp mechanism rather than by an ordinary function return. In some circumstances, ct_return() may be more efficient or more convenient. By default, ct_return() is disabled in order to avoid overhead for applications that don't use it, but you can enable it by using a compile-time macro.

• Minor feature enhancements

Release Notes: The message-passing machinery now uses a reference-counting scheme to reduce the overhead of delivering messages. This change also reduces the use of memory, especially when distributing long messages to multiple threads. The API is unchanged.

Release Notes: Cheap Threads now offers a timeout facility as a compiletime option. A thread may put itself to sleep and be awakened after a specified interval, if some other event doesn't awaken it first. There is now a mailing list for discussion and support of Cheap Threads.
