I’m very strongly in favor of Option #1 at this point, with a “release note” mentioning that 3.5.x will be the last series to support Java8.
I know we have plenty of services running with Java8 and have several customers that are still targeting Java8. I really think we need to keep Java8 as an option at this point, but let folks know that it will be changing.
