@ssande-fwd do you need to hardcode the dependency here? If you do that any bug fixes in those extensions will not be carried over.

    "fwd-float": "github:Forward-Education/pxt-fwd-modules/fwd-float#v1.0.5",
    "fwd-ph": "github:Forward-Education/pxt-fwd-modules/fwd-ph#v1.0.5",
    "fwd-lights": "github:Forward-Education/pxt-fwd-modules/fwd-lights#v1.0.5",
    "fwd-pump": "github:Forward-Education/pxt-fwd-modules/fwd-pump#v1.0.5"

I tried to do it without specifying version and it was not 100% reliable. Once it stopped fetching the latest version of a dependency I could never fix it. It happened a few times in a few different repos. I opened a ticket about it and was told to always specify the version because when you don't, behavior is undefined (I know its supposed to pull latest tag or latest commit if no tags).

@ssande-fwd can you point to the ticket?

@ssande-fwd We do cache the extensions for 24 hours in the CDN and local cache. So hardcoding is good for testing if you want to test immediately after bumping one after another. However, if you are releasing after testing, I would suggest not hardcoding unless you are worried someone else would change those dependencies without testing. Does it make sense? I will merge this for now.

The fetching of the wrong version persisted for days. I can make another issue if it happens again, but I don't see much incentive to not specify the version. I'll take stability and reliability over convenience, given the frustration I've experienced when it randomly doesn't work as expected and can not be fixed. Martin can correct me if I'm wrong but I think it's even part of the coding standards. I recall him asking me to specify a dependency version where I did not. Thanks for merging. Like I said I wanted to do it the way you are suggesting but I got pushback in several forms and from several directions.
