Switch firmware versions MS 15.14 changelog

HTTP proxy is no longer supported on MS 15+. Nodes that use HTTP proxy without any other means to connect to dashboard may fail to connect.
Moving or re-provisioning an MS390 stack in dashboard can cause the management plane of at least one member to stay offline until rebooted (present since MS 15.0)
MS390 upgrades to this version will result in a full system reload
MS390 series switches can only downgrade to MS 12 with an incremental step to MS 14
MS390s with a Group Policy ACL containing spaces or non-alphanumeric characters results in ports being initialized with incorrect configurations of trunk, native VLAN 1, until the system finishes booting

ARP Table Not Updated Upon Receipt of Gratuitous ARP Request
The local status page does not indicate to allow port 443 upstream for Nextunnel capable devices when they fail to connect to dashboard

MS390

MS390s with IPv6 only management will fail to connect to dashboard
In rare instances, MS390 stacks can experience a management plane restart
In rare instances, MS390 stack members can fail to perform an upgrade resulting in an errored state
MS390 upgrades can intermittently fail resulting in an upgrade loop
Powering off a MS390 member in a stack doesn't result in the member showing as offline in dashboard (present since MS 15)
MS390 switches do not generate event logs for guest or critical authentication, RADIUS server timeouts, or EAP status
In rare instances, MS390 ports will fail to initialize correctly on boot resulting in one or more ports remaining offline

IGMP querier is enabled on all VLANs resulting in IGMP messages being sent every 125 seconds. Layer 2 switches use the management IP as the querier address. (always present)
Networks containing a large number of switches may encounter issues saving changes on the Switch Settings page
In rare instances, RADIUS accounting sessions may not be removed after a client disconnects with an EAPoL logoff message (present since MS 11)
Broadcast types of traffic can leak into the Guest VLAN if a port that fails authentication has a voice VLAN configured, and dashboard has a Guest VLAN defined (present since MS 11)
AMI IP addresses do not send gratuitous ARP packets which can lead to packet loss if the AMI address has aged out in the network
Meraki authentication does not work with guest VLAN

Stacking

LACP bundles configured across stack members experience brief outages when a stack member goes offline and again when it comes online (present since MS 10)
Stack members may experience delays in updating their configuration for up to an hour after a config change (present since MS 9)
Stack ports may fail to initialize properly upon reboot. A subsequent reboot of the switch would be needed (present since MS 14)
Connecting a stacking cable to a stack that is online may result in a stack member going offline (present since MS 12)
Switch stacks will learn MAC addresses from ports in the STP blocking state which can trigger a constant flood of MAC flaps in the event log
LACP bundles spanning multiple stack members can result in a temporary loop if one of the stack members is rebooted (present since MS 11)

MS12X

In rare instances, MS120 series switches may have empty packet captures until they are rebooted
Links being established on an MS120 can result in neighboring ports to flap (present since MS 11)
MS120 series switches in extremely rare instances will experience reboots every few minutes (present since MS 11)
Ports with an odd-numbered MTU value fail to initialize for MS120/125 series switches (predates MS 11)

MS35X/42X

mGig switches will have an amber light for all physical ports that do not negotiate to the highest supported speed. Dashboard will continue showing a light green status for all ports above 100Mbps. For example, MS355 switch ports will incorrectly show an amber light for 1G, 2.5G, and 5G, but will show a green light for 10G.
MS350-24X and MS355 series switches do not negotiate UPoE over LLDP correctly (predates MS 10)
MS350/450 series switches in a stack configuration will lose dashboard connectivity if a "Deny Any Any" ACL is added without having higher "Allow" rules in place for dashboard connectivity (predates MS 12)
Enabling Combined Power on MS350/355 switches results in events being logged once per minute (present since MS 11)
When an SFP module is inserted/removed on MS420/425 series switches, BPDUs can be delayed leading to STP transitions in the network (predates MS 12)

MS390

MS390 management plane may encounter infrequent restarts (always present)
MS390 series switches in rare instances disconnect from dashboard until rebooted (present since MS 14.33)
MS390s in rare circumstances will experience a full system restart (preset since MS 14)
When the MS390 management plane experiences a restart, LACP flapping can occur
MS390s that receive incorrectly flooded CDP packets may incorrectly report VLAN mismatches and SFP port information (present since MS 12)
MS390 "Port Up/Down" events will be shown across all members
MS390 stacks may send frequent DHCP requests despite having a valid static IP address, which can result in IP flapping (present since MS 14)
MS390 series switches do not support loop detection
MS390 series switches do not support warm spare/VRRP
Moving or re-provisioning an MS390 stack in dashboard can cause the management plane of at least one member to stay offline until rebooted (present since MS 15.0)
Rebooting an MS390 switch in a stack via the UI will result in the entire stack rebooting
MS390s with a Group Policy ACL containing spaces or non-alphanumeric characters results in ports being initialized with incorrect configurations of trunk, native VLAN 1, until the system finishes booting

In regard to the IPv6 static routing support:

Where do we configure the appropriate IPv6 networks and addresses once the Upgrade to 15.18 is installed?

Our MS390 is on 15.18, but I can't find any option in the dashboard ..
