I am happy to announce Guppy 3 3.0.5 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. The main news in this release: o Wheel binary compatibility fix for Python >= 3.7, < 3.7.4 o Prefix thread states with interpreter number in RootState o Made first heap call faster o Use _PySys_GetSizeOf as default size getter o Allow xt_hd_traverse to be KeyboardInterrupt-ed License: MIT The project homepage is on GitHub: https://github.com/zhuyifei1999/guppy3 Enjoy, YiFei Zhu
