A mere three months after the PyPy project released version 4.0 of its just-in-time optimizing compiler for Python, it's unleashed version 5.0. The newest edition is a "faster and leaner" upgrade to one of the simplest and most direct tools to speed up Python applications.
PyPy tackles two ongoing issues -- startup time and memory consumption -- in this release. PyPy's maintainers claim warmup time (when a script is first parsed for execution and optimized for speed) and memory consumption can both be reduced by about 30 percent with some applications.
