+* The options `wayland.windowManager.sway.config.bars` and `opt-xsession.windowManager.i3.config.bars` have been changed so that most of the suboptions are now nullable and default to `null`. The default for these two options has been changed to manually set the old defaults for each suboption. The overall effect is that if the `bars` options is not set, then the default remains the same. On the other hand, something like:
