The GIT repository history is not telling the same. The only more or less considerably sized commit was done 16 minutes ago. The rest were one-liners, related only to founders reward and version bump.
If you indeed made some bug fixes in the initial commit, then why didn't you fork your repository from the original ZCoin one, so people could see the difference (if any). Creating an independent repository instead of cloning the original project is a bad practice, mostly aimed at hiding something.
