Comment (by ryandesign):

 The build now fails on Yosemite with:

 {{{
 Frameworks/OakCommand/src/OakCommand.mm:182:1: error: ARC forbids

 I find some hits for this error that says that in Xcode 7.3, this should
 work fine because the property is assumed to be `strong`, but for earlier
 versions, `strong` must be specified explicitly. I'll try this out...
