Deprecation notice: PluginOutlet arguments should now be passed using @outletArgs= instead of @args= (outlet: category-box-below-each-category) [deprecation id: discourse.plugin-outlet-args
This currently doesn’t seem to be breaking anything. So more just for information headsup
This is a deprecation notice, so if you are not a theme/plugin maintainer you have nothing to do about it and that won’t cause errors on your instance.
No as long as it’s a deprecation, we use these to track them and fix them ahead of final removal. It’s only YOUR problem, if it’s your own private customization causing this.
