I diffed the version on GitHub with the one downloaded from Dropbox (after verifying the Dropbox file's hash). The only changes to the GitHub version are the Readme file and that it was upgraded to target iOS 9.1, as well as some apparently minor changes in the XCode project file. So you won't get the same SHA sum, but all the files aside from those are the same. In particular, the "iflux" binaries are identical.
So it looks like the GitHub version matches the original.
I'm not 100% sure. The version from Dropbox has some differences in the Xcode project file, including a different "target version". The Dropbox version says it targets 8.0.
So it looks like the GitHub version matches the original.
