How can I download and run the latest in-development version of Apollo?
Keep in mind that if you try to run the very latest Apollo, there are no guarantees that it will work correctly. We are actively developing it, and often there are many bugs that crop up between releases and then are fixed. So on any given day, it’s possible that the up-to-the-minute Apollo won’t run at all (though that is rare) or that various aspects of it will be broken. Occasionally, someone will check in code that doesn’t compile; when this happens, it’s always fixed quickly (within a day). But if you get lots and lots of errors when you try to make, there’s probably something wrong with your environment (not having APOLLO_ROOT set properly is the most common mistake).
