And 18.104.22.168 156 was the GA release too. Available for ZD5K, ZD3K, ZD1100, and ZD1000 controllers.
Any APs you are using on 9.5 GA today, are also supported on all those controller platforms up to
version 22.214.171.124.44 MR3, or up to 126.96.36.199.13 MR2, 188.8.131.52.9 MR2, even 184.108.40.206.14 MR3 (unless you
have 2942 model APs).
Please consider discussing with your IT team, about scheduling a change management period
to perform an upgrade to your ZoneDirector (and all APs) firmware. You might contact TechSupt
to get further pointers, like disconnecting ZDs from the network while upgrading, as APs will re-join
and upgrade to whatever version the ZD is on when you're done.
If you have a support contract, you can download the controller firmware versions you need, and
please read the 9.8.3 Release Notes,https://support.ruckuswireless.com/documents/814-zoneflex-9-8-3-mr3-release-notes
It's Upgrade path says you need to be on at least 220.127.116.11.267 GA from your 9.5 current version, so
you would need at least two upgrades.https://support.ruckuswireless.com/documents/277-zoneflex-9-6-ga-release-notes
Official 9.6 upgrade paths supported:
You can upgrade from your 9.5 to the 18.104.22.168.267 GA version and then upgrade to 22.214.171.124.14.
I can say that 9.8.3 is likely more Apple friendly and would have the most enhancements, than
previous versions. Enable 802.11d country code in IE is something else about Apples that I recall.
Good luck and best regards.
