PyPy v7.3.7: bug-fix release of 3.7, 3.8¶
We are releasing a PyPy 7.3.7 to fix the recent 7.3.6 release’s binary
incompatibility with the previous 7.3.x releases. We mistakenly added fields
PyDateTime_CAPI that broke the promise of binary
compatibility, which means that c-extension wheels compiled for 7.3.5 will not
work with 7.3.6 and via-versa. Please do not use 7.3.6.
We have added a cursory test for binary API breakage to the https://github.com/pypy/binary-testing repo which hopefully will prevent such mistakes in the future.
Additionally, a few smaller bugs were fixed:
- Fix incorrect tracing of while True` body in 3.8 (issue 3577)
- Properly close resources when using a
- Fix the value of
_sysconfigdatain 3.8 (issue 3582)

We would like to thank our donors for the continued support of the PyPy project. If PyPy is not quite good enough for your needs, we are available for direct consulting work. If PyPy is helping you out, we would love to hear about it and encourage submissions to our blog site via a pull request to https://github.com/pypy/pypy.org
We would also like to thank our contributors and encourage new people to join the project. PyPy has many layers and we need help with all of them: PyPy and RPython documentation improvements, tweaking popular modules to run on PyPy, or general help with making RPython’s JIT even better.
If you are a python library maintainer and use C-extensions, please consider making a CFFI / cppyy version of your library that would be performant on PyPy. In any case both cibuildwheel and the multibuild system support building wheels for PyPy.
What is PyPy?¶
PyPy is a Python interpreter, a drop-in replacement for CPython 2.7, 3.7, and 3.8. It’s fast (PyPy and CPython 3.7.4 performance comparison) due to its integrated tracing JIT compiler.
We also welcome developers of other dynamic languages to see what RPython can do for them.
This PyPy release supports:
- x86 machines on most common operating systems (Linux 32/64 bits, Mac OS X 64 bits, Windows 64 bits, OpenBSD, FreeBSD)
- 64-bit ARM machines running Linux.
- s390x running Linux
PyPy does support ARM 32 bit and PPC64 processors, but does not release binaries.
