Events Update

PyData Global will be returning December 1-3! We hope you can join us for the third installment of this online event that brings together the global PyData community network across the globe. The Call for Proposals is open, and the deadline to submit is September 12.

We’re also very excited to share the news that there will be a PyData Miami on Sept. 22 and PyData NYC is returning this fall, November 9-11. Tickets for PyData NYC are now available (Early Bird close on September 5). The Call for Proposals is open through August 24.

The inaugural PyData Tel Aviv will take place on December 12. Stay tuned to our social media channels as we release more information on these upcoming events!

Lastly, we previously had announced the NumFOCUS Open Science Community Summit. Unfortunately, due to a scheduling conflict, we will postpone this event until 2023. We’ll share more information as it becomes available, so stay tuned!

Announcing Python Software Foundation Fellow Members for Q2 2022! Matplotlib wishes to welcome the new PSF Fellows for Q2.
md analysis


New 2.2.0 release including Apple M1 packages (and they wish to extend a thank you to conda-forge).

  • MDAnalysis took over stewardship over the panedr repository, a specialized library to read a specific data format produced by the widely used GROMACS molecular dynamics package. panedr will become a dependency of MDAnalysis as part of one of the current GSoC projects.


Hiring update

NumPy logo


The NumPy team is pleased to announce the release of NumPy 1.23.0rc2. The NumPy 1.23.0 release continues the ongoing work to improve the handling and promotion of types, increase the execution speed, clarify the documentation, and expire old deprecations.

Release highlights:

  • Implementation of loadtxt in C, greatly improving its performance.
  • Exposing DLPack at the Python level for easy data exchange.
  • Changes to the promotion and comparisons of structured dtypes.
  • Improvements to f2py.

The Python versions supported in this release are 3.8-3.10, 3.11 will be supported when it comes out. Note that 32 bit wheels are only provided for Windows, all other wheels are 64 bits on account of Ubuntu, Fedora, and other Linux distributions dropping 32 bit support. All 64 bit wheels are also linked with 64 bit OpenBLAS. Wheels can be downloaded from PyPI; source archives, release notes, and wheel hashes are available on Github.
openFHE logo


As mentioned in the last newsletter edition, PALISADE is now OpenFHE, and there has been an official public release!

OpenFHE is a next-gen open-source homomorphic encryption library that merges several previous open-source FHE libraries. OpenFHE supports all of the major post-quantum FHE schemes. This means OpenFHE even protects against nation-state quantum computing attacks. OpenFHE also includes a native Hardware Abstraction Layer (HAL) to natively leverage commercial hardware accelerators for greater performance when needed.

You can find the project webpage with extensive links to documentation and supporting material at!

Like PALISADE, OpenFHE is officially affiliated with the non-profit NumFocus open source consortium as a fiscally sponsored project. OpenFHE is a culmination of years of effort and expertise in designing, developing, applying, and deploying Fully Homomorphic Encryption (FHE) in real-world scenarios and is the result of extensive collaboration between researchers, scientists, and engineers from Duality, Intel, Samsung, MIT, and over a decade of support from DARPA. OpenFHE is available on the 2-clause BSD open-source library, and it will ALWAYS be open-source.

OpenFHE wishes to welcome new members and contributors to the community. Please subscribe to the Google mailing list for OpenFHE project announcements or join the discourse forum.
PyMC logo


PyMC released version 4.1.3, and the full changelog is available for reference.

PyMC and Data Umbrella have organized a series of open source working sessions. For more details, instructions, and how to participate, see the July 2022 PyMC OS Working Sessions website.

SciPy 1.9.0 was released!

Release highlights:

  • This has modernized the SciPy build system to use meson, substantially improving build performance and providing better build-time configuration and cross-compilation support.
  • Added scipy.optimize.milp, new function for mixed-integer linear programming
  • Added for fitting discrete and continuous distributions to data
  • Tensor-product spline interpolation modes were added to scipy.interpolate.RegularGridInterpolator
  • A new global optimizer (DIviding RECTangles algorithm)

SciPy has recently been awarded a Small Development Grant from NumFOCUS to work on Faster Random Variate Sampling from SciPy Statistical Distributions.

At SciPy 2022, several SciPy contributors made presentations, met for the first time, and hosted a sprint, during which ~10 new SciPy contributors submitted their first PRs

SciPy has recently hit 10k stars on GitHub! If you haven’t already, please add your star to the SciPy repository and help show how large the community is!
stan logo


Stan is having an open call for StanConnect event proposals and is currently looking for those interested in coordinating an event with the help of members of the Stan Governing Body. Topics can be centered around a community, such as Stan for Ecology, or around a specific modeling framework, as broad or narrow as that may be.

StanConnect events will be hosted online to ease with recording of the sessions. If you are interested or simply want to learn a bit more about what organizing a StanConnect event might entail, please reach out to
zarr logo


  • ZEP0001 is open for review and Zarr looking to build consensus from the Zarr Community. If you use Zarr in any way, please have a look and provide your feedback.
  • Read the latest blog post: Zarr EOSS4 Roadmap! Feedback and suggestions are welcome.
  • Zarr is also looking to showcase #ZarrData on the Zarr website: If you have something interesting, please let the project know!

GNU Radio

For those interested in SDR or who want to learn more about RF signal processing, the annual GNU Radio conference is approaching, Sept 26-30, in Washington DC. Registration is open:
mesa logo


With Mesa 1.0 released, a strategy session followed to think about the project’s development holistically. Integrated with the discussion was looking at a Mesa-based COVID model from the National Center for Supercomputing Applications.

Takeaways and themes from the Mesa strategy discussion:

  • Develop the Mesa Community: How does Mesa grow a more robust and resilient community? This question also brought up the discussion of how open source libraries grow and develop, and Mesa wants to conduct research along these lines.

Some suggested avenues:

  • Continue to engage with institutions we have relationships with TUDelft, U. Mary Washington, George Mason, and developing with U. of Illinois Urbana-Champagne.
  • Engage more heavily with NumFOCUS and learn from other successful projects.
  • Engage with organizations such as RSE!
