--comp-lzo is deprecated in OpenVPN 2.4. Use --compress instead.

Hello,

I just saw this
"--comp-lzo is deprecated in OpenVPN 2.4. Use --compress instead."
on page https://github.com/OpenVPN/openvpn/blob/release/2.4/Changes.rst

But the manual page doesn't have any information about --compress option.
Is it absolutely the same than --comp-lzo?
It is compatible with previous openvpn server versions 2.3.18 ?

My problem is: I am actually in process to renew over 100 openvpn servers and over 3000 client keys. Now I want absolutely be sure to have the right option for the next years!

By the way:
I connect with client software 2.4.4 on a windows computer to openvpn servers with openvpn version 2.3.18.
I want to be sure that the --compress option works with all openvpn server versions.

2.3.18 does not support --compress so you can only use --comp

Also, you may want to read about VORACLE and disable your compression all together.

Or upgrade your servers because 2.3.18 does not get new features it only gets critical security patches.

I am not able to use newer openvpn versions on the server side. They are industrial routers which don't use the 2.4 versions so far. I hope they will support it in future.
