We have just released Flox 1.7.1. This release includes Flox generations, a lightweight version control mechanism for FloxHub environments. This will allow you to quickly roll back changes to a FloxHub environment, or recreate a specific point in history. Flox 1.7.1 also contains improvements to flox activate for zsh users and several minor fixes.
