GitHub has started the early phases of rolling out a solution for git repositories that contain large files. It looks pretty interesting and takes git one step closer to being a more attractive solution for companies that track huge files or even binaries that can’t be diff’d. This would be especially useful for game assets. I look forward to keeping track of the progress!
Git Large File Storage (LFS) replaces large files such as audio samples, videos, datasets, and graphics with text pointers inside Git, while storing the file contents on a remote server like GitHub.com or GitHub Enterprise.
