+title: Goodbye, Python 2! Hello, New Buildbot!
+layout: post
+---
+
+At long last, Void is saying goodbye to Python 2. Python ended support for
+Python 2 in 2020, but Void still had over 200 packages that depended on it.
+Since then, Void contributors have
+[updated, patched, or removed](https://github.com/void-linux/void-packages/issues/38229)
+these packages. For the moment, Python 2 will remain in the repositories as
+`python2` (along with `python2-setuptools` and `python2-pip`). `python` is
+now a metapackage that will soon point to `python3`.
+
+One of the biggest blockers for this project was some of Void's own infrastructure:
+our buildbot, which builds all packages for delivery to users. For a long time,
+we were stuck on buildbot 0.8.12 (released on 21 April **2015** and using Python 2),
+because it was complex to get working, had many moving parts, and was fairly fragile.
+To update it to a modern version would require significant time and effort.
+
+Now, we move into the future: we've upgraded our buildbot to version 4.0, and
+it is now being managed via our orchestration system, Nomad, to improve
+reliability, observability, and reproducibility in deployment. Check out the 2023
+*Infrastructure Week* [series of blog posts](/news/2023/07/infra-week-day-1.html)
+for more info about how and why Void uses Nomad.
