Square-o icon is deprecated, where to update?

On a hosted instance of Discourse using the discourse-solved plugin, I’m getting a deprecation notice that the Font Awesome square-o icon needs to be replaced with far-square

I’m not finding an option to configure the icons used in this plugin. Could someone please point me to where I’d do that or assure me it will be taken care of for me?


It will be taken care of.

Those warnings are just tips for developers of features that will be removed in future versions.
