@dorny I'm afraid that this is not enough.
looks like there's also a need in updating the "setOutput" call as per this doc:
https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions

here are the places that I could find that are in need of this change:

@dorny looks like it was addressed by this PR in the "actions/typescript-action" repo:
https://github.com/actions/typescript-action/pull/611/files#diff-468016aae139513ca1e5421e59385204d06350f7fb00672a31184f70f4eb3425

@IdanYaffe thanks for the notice. Here's a blog post about it - https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

So updating the package should be enough. I will do it now.

@dorny I'm afraid that's still not resolved.
if I'm not mistaken, we need to update the setOutput function in the index.js:
https://raw.githubusercontent.com/dorny/paths-filter/master/dist/index.js

should be something like this:
https://github.com/actions/typescript-action/blob/main/dist/index.js#L355-L362

Yes, I have to update the index.js. It's a packaged version of all the code of this action and its dependencies. I usually do it just once after multiple PRs are merged, together with adding a new tag. The file is big so every change of it increases the size of the repo. Looks like I won't make more changes today so I will do a release shortly.
