Indeed Smart-1 Cloud statement is to supply the latest and greatest security management. It took a while in the transition from 81 to 81.10, it's going way faster with 81.20 many happy customers already have an environment with 81.20, since the GA that was 7 weeks ago (new customers launched with 81.20 a week after GA).
It's a gradual upgrade to 81.20 of all customers environments, within several weeks all customers will be upgraded to 81.20. Upgrades are done in off hours and customer receives a notification email several days before with the schedule range in which it will be performed.
Regarding the CEF format this is still being checked, @Alex- please share the SR number in the private channel
Also, thank you @Alex- for the comment regarding the What's New SK, we have What's New banners on S1C UI on infinity Portal for a while now, but leaving outdated SK was not the intention. Will be taken care of one way or another.
