The main development effort this release was to make the Windows installer work again. We also merged a recent performance improvement in the JIT, which allows us to run larger programs (for example, alex, the Python compiler) faster.

We also finally merged the cpyext refactoring, which means that PyPy now supports CFFI out of the box for all supported architectures.

We’re getting ready for PyPy.js, a project we started to make PyPy work in a web browser. The first version of PyPy.js will be released soon, probably around the time of the next PyPy release. PyPy.js will be a research project, and does not have a long-term commitment from the core PyPy developers.

We’re also working on getting PyPy to run on the GPU. We’re not the first, but we’re hoping to do it in a new way, by moving the stack and the heap to the GPU, leaving only the interpreter on the CPU.
