I am happy to announce Guppy-PE 0.1.11 Guppy-PE 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. The main news in this release: Contains notes and check that this package is only for Python2. A version for Python3 is recommended and is available here: https://github.com/zhuyifei1999/guppy3 License: MIT The project homepage is on GitHub: https://svenil.github.io/guppy-pe/ Enjoy, Sverker Nilsson
