Hi there, I'm your code-tour driver today :D. The majority of these fixes aren't live yet, but keep an eye on dw_maintenance for when they'll be pushed onto the main server.

Contributors for this tour: stormerider, kaberett, sophie, hotlevel4, kariela, swaldman, misskat, exor674, ninetyd, fu, and momijizukamori.

Onward!
