I am happy to announce Guppy 3 3.0.6 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. The main news in this release: o Bug fixes & removal of unused code o Windows now gets output from _PyObject_DebugMallocStats with xmemstats() o More code is now tested, and some unported code, mostly found by these tests got ported License: MIT The project homepage is on GitHub: https://github.com/zhuyifei1999/guppy3 Enjoy, YiFei Zhu
