This is good:

As a consequence of that, you can now export your stashes to a single reference, and then push or pull it like you would a normal branch or tag. Git 2.51 makes this easy by introducing two new sub-commands to git stash to import and export, respectively. You can now do something like:

$ git stash export --to-ref refs/stashes/my-stash
$ git push origin refs/stashes/my-stash

on one machine to push the contents of your stash to origin, and then:

$ git fetch origin '+refs/stashes/*:refs/stashes/*'
$ git stash import refs/stashes/my-stash

on another, preserving the contents of your stash between the two.
