* version 0.80 (2006 10 27)

82 83 84 85 86 87 88 89 90 91
    This is a version with important changes to support
    multi-threading. This version provides two kinds of threads: LURC
    threads and Posix threads (aka pthreads). LURC threads are
    implemented using the LURC library, the Light ULM/Reactive library
    for C developed at INRIA. LURC supports the creation of
    synchronous cooperative threads, synchronizing and communicating
    with each other using signals in a deterministic scheduler (see
    http://www-sop.inria.fr/mimosa/Stephane.Epardaud/lurc for
    details).

    The main changes in this release are: a new back-trace system, a
    conform call/cc/dynamic-wind implementation and some performance
    enhancements.
