Warning when running an outdated version

[izakp]

@alloy Not sure how to approach this other than checking https://pypi.org/project/hokusai/#history every time Hokusai runs, which seems excessive

Perhaps somehow tying it to the project config would be better

Yeah good question. Maybe we can identify certain commands where it really matters? I assume there’s no other requests that are regularly made anyways that we could piggy-back off?

What if we were to track releases via GitHub and check once every X interval (hour, day, etc) across any Hokusai command?

Upon any command execution, if we haven't checked within the past X interval, hit the GitHub API and compare versions. If the local Hokusai is out of date, show a warning? Maybe prompt to upgrade or continue?

Yeah good point, at most once an hour is probably a good interval, but then I do think we should do it synchronously before the command does any other work and maybe even ask:

There’s a new version, are you sure you want to continue this with an outdated version? [y/N]

I like that! 👍
