## Announcing CLI11 2.0

CLI11, a powerful library for writing beautiful command line interfaces in C++11, has been updated to 2.0. A lot of deprecated things have been removed, and there was a lot of cleanup under-the-hood; making CLI11 simpler. A few defaults have changed slightly, like better TOML support by default.

CLI11 does a better job than ever understanding any sort of container you provide - complex numbers are natively supported, along with atomic types. A long requested feature, simple version flags, has been added. Subcommands are more customizable. And there have been quite a few bugfixes for rare issues.

## Setup an Apple Silicon Mac

I recently got an M1 mac, and I’ll be cataloging my experience with using it for scientific software development. I’ll be returning to update this page periodically, and will eventually have a focused recommendation for Apple Silicon setup, similar to my Intel setup.

## 🎡 cibuildwheel 1.8.0 and 1.9.0

cibuildwheel has just had two back-to-back releases, two weeks apart, representing several months of hard work and some exciting few features! I will be covering both releases at once, so we will discuss Apple Silicon support, architecture emulation on Linux, integrated PEP 621 Requires-Python support, the native GitHub Action, extended build and test controls, and more!

If you are following the releases, 1.7.0 came out last November (2020), and included the fantastic output folding feature, which makes logs much easier to read on CI systems that support folding, and makes it much easier to see how long each step takes. The 1.7.x series also included the addition of the working examples section of the documentation, which tracks some known projects using cibuildwheel, such as scikit-learn, Matlotlib, and MyPy; it is a great place to go to look into how other projects have integrated cibuildwheel into their workflow.

I have an general overview post as well. Now let’s look at what’s new! Update: cibuildwheel is now an official package of the PyPA!

## Overview of cibuildwheel 🎡

This is the first of two posts on cibuildwheel, a fantastic project I joined after switching to it from my own azure-wheel-helpers, which I’ve blogged about here before. It is the best wheelbuilding system available for Python today, and can make something that is normally a pain to setup and a headache to maintain a breeze (by forcing all the headaches on us, of course, as maintainers, but it’s better to solve issues centrally! Obviously we rather like solving these problems. Or we are just crazy, which is also possible ;) ).

Be sure to checkout the followup post over new features in 1.8.0 and 1.9.0, too! Also, cibuildwheel was recently accepted into the PyPA!
