I am happy to announce Guppy 3 3.0.7 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 Disabled glibc malloc hooks because of thread safety issues o Optimizations to the dictof classifier by using GC objects o No more stack overflows during heap traversal o Tab completion with rlcompleter on a UniSet is no longer so expensive License: MIT The project homepage is on GitHub: https://github.com/zhuyifei1999/guppy3 Enjoy, YiFei Zhu
