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 License: MIT The project homepage is on GitHub: https://github.com/zhuyifei1999/guppy3 Enjoy and Happy New Year, YiFei Zhu
