Introducing the PyPy 1.2 release

“We are pleased to announce PyPy’s 1.2 release. This version 1.2
is a major milestone and it is the first release to ship a
Just-in-Time compiler that is known to be faster than CPython (and
unladen swallow) on some real-world applications (or the best
benchmarks we could get for them). The main theme for the 1.2
release is speed.

“The JIT is stable and we don’t observe crashes. Nevertheless we
would recommend you to treat it as beta software and as a way to
try out the JIT to see how it works for you.

“Highlights:

* The JIT compiler.
* Various interpreter optimizations that improve performance as
well as help save memory. Read our various blog posts about
achievements.
* Introducing a new PyPy website at pypy.org made by tav and
improved by the PyPy team.”
