Can I use a static version of PsychoJS?

A recent commit to the PsychoJS library made our experiment crash for a whole bunch of participants and may have cost us several hundred dollars. Is there a good way to run experiments using a stable version that is not subject to change?

I think I could edit the js file to import an earlier version of PsychoJS, but I’m currently working in Builder and that would be a pain. It seems strange that the default is to use a library that’s in active development. Can I change that?

@sotiri, @apitiot – you’ve been the ones dealing (heroically!) with this fallout. Can you advise me on how to avoid this type of problem in the future?
