    Here is a list of major additions and changes since the last release:

    1. Improving testing code:
    doc/EXAMPLE/ATSLF,
    doc/EXAMPLE/INTRO, doc/EXAMPLE/TESTATS
    Kudos to Artyom Shalkhakov!
    2. Introducing various keywords (e.g., abstflt, absvtflt), which are
    used in the implementation of ATS3(ATS/Xanadu)

    Please note that starting in this release, there are two variants of
    the package released: The "gmp" variant depends on the GMP library and
    the "int" variant does not depend on the GMP library. In this release
