June 2023 release
Changelog: https://github.com/jupyterhub/repo2docker/blob/2023.06.0/docs/source/changelog.md
Breaking changes
- JupyterHub version installed by default upgraded from 1.5 to 3.1.1
- Microsoft killed MRAN, so all package snapshots now come from Posit Package Manager. Snapshots from before 2018-12-07 are now no longer available, so you might have to update the snapshot date in your
runtime.txt
