I am happy to announce Guppy 3 3.1.1 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 Added linux aarch64 wheel builds o Added warning about pywin32 < 300 if it's imported, due to crash when traversing its heap.
