PyPy v7.3.4 is out. The release note is here


The blog post should appear soon. The downloads are available on

https://pypy.org/download.html <https://pypy.org/download.html>

or directly from


Now on to the next release.

Here are a few things it would be nice to push forward, there is work 
progressing on some of these and contributions are welcome:

- Python3.8

- Close the gap on known slowdowns:

    - A faster _pickle module implemented in RPython

    - A faster json writer

    - Better handling of too-many-traces in the JIT (for both too large 
loops and too much specialization)

- Making HPy viable for some small c-extensions

- Fix these packages so they work with PyPy: hdf5 [0], grpcio [1]
