I am happy to announce Guppy 3 3.1.5 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 3.13, and support for Python 3.8 was dropped. Code for Remote & Monitor has been removed since it no longer worked since Python 3.9 (I hope PEP 734 will change this in the future). Other libraries such as aiomanhole might provide similar functionality with a much simpler implementation. This release also fixes a few bugs, including: o Fix -Wmissing-braces compile warning o Added some error handling code paths to bitset License: MIT The project homepage is on GitHub: https://github.com/zhuyifei1999/guppy3 Enjoy and Happy New Year, YiFei Zhu
