================================== PyPy 1.7 - widening the sweet spot ==================================We're pleased to announce the 1.7 release of PyPy. As became a habit, this release brings a lot of bugfixes and performance improvements over the 1.6 release. However, unlike the previous releases, the focus has been on widening the "sweet spot" of PyPy. That is, classes of Python code that PyPy can greatly speed up should be vastly improved with this release. You can download the 1.7 release here: http://pypy.org/download.html

The main topic of this release is widening the range of code which PyPy can greatly speed up. On average on our benchmark suite, PyPy 1.7 is around **30%** faster than PyPy 1.6 and up to **20 times** faster on some benchmarks. .. _`pypy 1.7 and cpython 2.7.1`: http://speed.pypy.org
If I understand right, pypy is generally slower than cpython without jit and faster with jit. (There is obviously a spurious datapoint in the pypy-c timeline for raytracing-simple.) This site is a nice piece of work.

I strongly recommend that where it makes a difference, the pypy python3 project target 3.3. In particular, don't reproduce the buggy narrow-build behavior of 3.2 and before (perhaps pypy avoids this already). Do include the new unicode capi in cpyext. I anticipate that 3.3 will see more production use than 3.2
