Hello, I have two questions regarding the maintenance mode. When maintenance mode is enabled. How are currently active users affected? Especially what happens if a user is typing/submitting a post while maintenance mode gets activated. Is there a way to controll maintenance mode besides the admin panel? CLI or RestAPI maybe? Thanks for your insights. Nils

I just tried out 1.4.2 on my docker image. The result: No Google fonts error and it starts up. So, whatever caused the problem is gone in 1.4.2. Very nice.
