Is there any possibility of unexpected errors being displayed?

Is there any possibility of unexpected errors being displayed?

I don't believe so. The display_errors is set per environment in app/Config/Boot/, so from this point of view, nothing has changed. However, this will enable adjusting settings for any other environment, like staging etc., when added.

Okay, the risk seems very very low.

@michalsn no no, It is worth updating the changelog. This fix is not specified in 4.6
