If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. The way Github handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see CONTRIBUTING.md for more information.

Nice catch @bengesoff ! Unfortunately, this was my mistake: at the last minute, I changed it to 0.3.0, which is better in this case. I'd rather upgrade the paragraph to talk about 0.3.0. Would you mind changing this PR to do that instead?

[bengesoff]

Quite a lot of refactoring to do given that Cargo.lock and versioning was discussed in detail later on!

[steveklabnik]

these two sets shouldn't change, actually... more below

Sorry for the extra nits, I should have mentioned it upfront :(

When you specify 0.3.0, it is short for ^0.3.0. So, we'll still get 0.3.8 today. does that make sense?

[huonw]

A version specifier 0.3.0 is actually satisfied by 0.3.x for any x, in particular cargo will take the latest release in the 0.3 series, so it will still be using 0.3.8.

(I personally just write, e.g. rand = "0.3" and skip specifying the minor version usually.)

Thank you for clarifying - I have learnt something new 😊

(Also, the reason that it was inconsistent was because I too learned something new, haha!)
