Why do you use date as cache-version?
And also, I wonder if we need cache-version. Are there any cases that
hashFilesis not sufficient?There was a problem hiding this comment.

It is an old practice to allow invalidating caches when it is contaminated by a broken CI workflow.
However I always hesitate to update the version one: it looks like having a special meaning. Using a date looks more meaningless.

gh cache deletewhen it is contaminated instead of usingcache-version?There was a problem hiding this comment.

It looks reasonable, I removed the
cache-versionparameter. Thanks for the info!
