# Versions

> Versions in Agent host: every save is immutable, deploy activates one and pushes it to the agent, roll back activates an earlier one.

Source: https://agenthost.geenius.io/docs/versions/

Every save creates a **version** that never changes. **Deploy** activates a version and pushes it to the agent. **Roll back** activates an earlier one. You can see what each version said.

You can also **pause** and resume an agent, and **archive** one you no longer need; archived agents do not count against your plan.
