Hello to all Overflow (Piper PL) fans! Just to let you know that version 0.4.1 has been released. It's mostly a bugfix release, and it should be more stable than 0.4.0. One new (experimental) feature is the ability to have multiple threads in an Overflow program. This is done using the new "SerialThread", "ParallelThread" and "ThreadJoin" nodes, as illustrated in examples/mixedthread.n Have fun!
