asqueella did everyone a favor and tweaked the breadcrumbs’ subof template to work without modification in any localization of the MDC wiki. Way to go!
We’re going to hold off on switching to the new breadcrumbs until after we get the MediaWiki 1.9.3 upgrade deployed, though, so that we can make sure that critical upgrade goes smoothly before we mess with the breadcrumbs.
We hope to throw the switch early this coming week, so please help us test the upgraded MDC wiki on the staging server! Make whatever changes you like there — they’ll be thrown out when we throw the switch, so please test everything you can.
