Actually, there is no an EoS Edge Client version itself.
Prior to v13.1.0, Edge client was bonded to the APM firmware version.
Starting with v13.1, it is possible to upgrade the edge client version independently. Anyway, all releases are supported as far as they work under one supported APM release.
F5 support policy states this:
"Starting with BIG-IP APM 13.1.0, BIG-IP Edge Client is available as a standalone package that can be installed on BIG-IP APM running 13.1.0 or later. BIG-IP Edge Client versions are not statically tied to a specific BIG-IP version. As F5 releases new client versions, you can install them to an existing BIG-IP system.
For these client versions, F5 Support offers assistance for customers with a valid support contract and a currently supported BIG-IP APM version. F5 provides software fixes in the current latest major released version and one version prior."
