Can someone fill me in please?
There were a couple issues that warranted a new release. The visible ones are related to our switches, and are in the release notes (I'll paste that section below). There are also some invisible changes in access point images laying the foundation for features that will be delivered in the future. Those changes are not mentioned in the release notes.
Addressed Issues in HiveOS 6.4r1a
35405 After an SR switch (SR2024/SR2124P/SR2148P) was upgraded during a time when the link between the AP and the SR was down, all VLANs configured on the switch port were removed.
35335 If an SR switch trunk port is configured using the CLI command “interface eth1/1 trunk allow vlan all” to allow all VLANs, any new VLANs configured after this command was invoked were not be added to the allowed list.
Hope this helps.
