    I am happy to announce Guppy 3 3.1.6

    Guppy 3 is a library and programming environment for Python,
    currently providing in particular the Heapy subsystem, which supports
    object and heap memory sizing, profiling and debugging. It also
    includes a prototypical specification language, the Guppy
    Specification Language (GSL), which can be used to formally specify
    aspects of Python programs and generate tests and documentation from a
    common source.

    Guppy 3 is a fork of Guppy-PE, created by Sverker Nilsson for Python 2.

    This release adds support for Python 3.14, and support for Python 3.9
    was dropped. Support for free-threaded mode is planned for a future
    release.

    This release also fixes a few bugs, including:

    o Fix a segfault in hv_cli_inrel_classify caused by a GC race
    o Fix relate of frame objects showing some attributes as exposed to Python
    when they are not
