To be completely honest - probably nothing. This is a legacy issue on our end, not yours. I haven't even taken the time to explore migrating our GH/Codeship builds to GL CI. We essentially mirror our repos amongst both offerings at the moment, running builds via Codeship until either they support GL and we can drop GH, or we get the time to spend on a proper Codeship => GH CI migration and we can drop Codeship. Anyone's guess what will win out at this point :)
Appreciate the response either way.
