While we are busy working on 3.4 we have to release a security release today. 3.3.6 fixes a minor security issue, which affects installations on .dev domains or behind reverse proxies that have no registered Panel users yet. Read more about it here: Release 3.3.6 · getkirby/kirby · GitHub
What do you think about updating the version in the https://github.com/getkirby/kirby/blob/master/SECURITY.md file?
Didn’t you say Kirby version 3.3.6 is a “security release”?
