Upgrading the Agent

IMPORTANT: Beginning January 31, 2023, the agent end-of-support policy will take effect. Per this policy, we will support agent versions that are under two years old. On a quarterly cadence, we will deprecate and no longer support agent versions that are older than two years. At the end of January, we will support Agent v4.16.0 and above. If you need help upgrading your agent to a supported version, contact securitysupport@fastly.com.

NOTE: Check the Agent Release Notes to see what’s new in the agent.

Our Agent package is distributed in our package repositories. If you haven’t already, configure our repository on your system.
