I just talked to support yesterday and they told me that the 205 is not getting updated past 6.5.4.6. I am none too happy about it. I have a cluster of 205s, 215s and 315s. I am not sure why they would opt to leave the 205 out of the latest version, as it is the same product family as the 215.
What this means is that either my cluster has to remain at 6.5.4.6 or I would have to have 2 clusters. Which would be ridiculous.
I am supposed to hear back from a member of the engineering team today. I will let you know if they tell me anything different.
