Not needed in developer changelog as we automatically migrate existing setting and if that doesn't work then we still support previous settings for BC (important as it is a security related feature, not always do config changes work eg when they forget to distribute it across multiple servers etc). Also it's not a developer setting but just a regular user setting.
once merged will need to update the FAQ (I'll do this)
@sgiehl applied the review comments. replaced the word also in few other places but not in places like the validator or so when it requires changes across plugins as it's not as easy to do and needs a separate PR anyway
Seems you added the screenshot directly, and not to LFS...
