We are a few versions behind. I am getting compatibility notice. Stable version is 12, but note mentions multiple update steps may be needed.
From release notes: “Direct upgrades from 10.10.7 and 10.11.x to 12.0 are supported; intermediate upgrades are not required. Users running releases older than 10.10.7 are strongly encouraged to upgrade to 10.10.7 before migrating to 12.0.”
