I think you’re missing a word or two.

Based on comments elsethread, I think what was meant is: You can install it now with “bun upgrade --canary”, or something along those lines.

However, people also report that the canary version doesn’t identify itself as version 1.4.

It does.

It's extremely obvious what they meant, even if it/or wasn't a common phone autocorrect typo.

Did you find the other ones?

The other one - singular - is a superfluous 'we'. It's perfectly clear.
