Upon upgrading from Extreme Campus Controller version 4 to version 5, the
appliance certificates are extended. Firefox browsers may see this validity extension
as a security violation. To resolve, follow FF's procedure for certificate management
and remove any certs it may have cached for the appliance(s).

Certain wireless clients (such as Qualcomm Killer Wireless 1535 and Intel
7265D/8260/8265) have been known to not complete the 4-way handshake in order
to fulfill the association process in networks that have both PMF/MFP (802.11w) and
Fast-Transition (802.11r [FT]) enabled.
The currently recommended workaround is to not enable PMF/MFP configuration on
a service that is also using 802.11r. Such clients have been demonstrated to work
correctly on services with just 802.11r (FT) enabled.

addressed in a future release.
None
A reboot of the peer Extreme Campus Controller is required when Availability is
configured for the first time to ensure synchronization of the configuration of
ONBOARD attributes, such as device groups. This issue will be addressed in a future
release.
ECA-622
GUI Mesh Report is missing the information about the Root AP with Ethernet
connection. This problem will be addressed in a future release.
ECA-565
The switch primary/backup availability is not supported on the EXOS switches running
the 3.4.1.8 Cloud Connector. This affects the deployments where two appliances are
configured in an Availability Pair. If the primary appliance is going down, then the
EXOS switches will not send statistics to the backup appliance and will be marked in
red "Critical" state. When the primary appliance is coming up again, the switches will
resume sending statistics information to the primary appliance and the state of the
switch will be marked with a green "Running" state.
ECA-455
Allow UTF-8 characters in JSON payload for all Rest API so non-ASCII / Unicode
characters are accepted in Rest API requests to comply with current Rest API
standards.
ECA-321
If a license violation is corrected, the license violation banner and GUI notification bell
are not cleared until the page is refreshed. Similarly, in a new installation, after a
license is installed, refresh the page. This issue will be addressed in a future release.
