I upgraded my Clara. Side-loaded fonts now have Advanced features in ePubs without plugins (I should have said "patches" not "plugins" — sorry for any confusion). (Or has it always been that way?) But what's a little odd is that the Font Face and Preview no longer show the side-loaded font you've got loaded — though it works fine when you get back to your page. (EDIT: This is in Advanced Settings, which didn't work with ePubs for side-loaded fonts at all before — without plugins anyhow.) (EDIT 2: Works right in KePubs for Preview — also there is now a slot for Supplemental fonts that I don't remember seeing before.)
