> Why would you want to pull a version that is newer than the author of the library you depend on has actually tested with?

1. To install a security update or bug fix update you need in a transitive dependency that the author of the dependency you're using hasn't updated to.

2. To use the same workflows across all my dependency management tools (npm, cargo, composer, bundler, and the rest of the lot follow the same patters and vgo goes against the patterns used by the others)

There are two reasons.

You can do 1), you just have make that an explicit dependency of your own. It just won't grab newest by default for sub-dependencies. So yes, you can pull the latest.

2) seems like a bit of a silly reason, if we all wanted to make everything work the same all the time we wouldn't make much progress or try anything new. Whether vgo's approach is correct or not we don't know yet, but saying that it isn't familiar isn't a good enough reason to not try it out.

To me, vgo matches what we already do in our python projects with a lot of dependencies. Pin everything in a freeze and upgrade on a schedule when we need to. We have seen far too many failures doing it any other way. (IE, using the "latest" of everything, which often either breaks semantic versioning and actually breaks or has subtle bugs that didn't exist before)

Using something like pip-compile, or literally `pip freeze > requirements.txt`?

[nicpottier]

The latter yes.

3. To apply bugfixes that affect you, but weren't exposed by your direct dependency's tests.
