I saw this. And that's why I'm asking. I would like to get a confirmation of this, because I also got an email from Ruckus, where was stated "You and your customers will receive software updates, regardless of support contract status.". I have 184.108.40.206 in quite a lot of sites and there is no support contract on those ZDs anymore...
I was a little surprised by that statement as it tacitly implies that Ruckus would backward port a KRACK fix into all versions of ZD firmware. That could involve a very large number (100+ ?) of firmware images stretching back many years. That's a shedload of regression testing.
I expected that only the last issued/latest firmware for EOL products would receive a refresh with fix. Perhaps others will appear over the next few weeks/months.
Michael B: if you are reading, care to comment on older firmware with KRACK fix?
