PyPy 1.4 brings speed improvements
PyPy, which the developers say is a fast and very compliant Python interpreter, is now available as version 1.4. Written mostly in Python, PyPy is almost a drop-in replacement for CPython and this is the first release of the interpreter that is considered production ready.
Thanks to PyPy's Just In Time (JIT) compiler, prospective users are promised a considerable boost in speed for most long running tasks, compared to the reference Python implementation. PyPy offers greater flexibility than the regular Python semantics, a more efficient use of memory, sandboxing for untrusted code and a stackless mode, providing micro-threads for massive concurrency.
The interpreter is available for downloading as 32 or 64-bit binaries for Linux, Windows and Mac OS X, or as source from the PyPy.org web site. Documentation is provided and PyPy is released under a MIT-like licence.
