Instead of this:

      - name: Make release
        id: release
        env:
          NPM_TOKEN: ${{secrets.NPM_TOKEN}}
        run: |
          yarn -s dripip preview --json > result.json
          result=$(cat result.json)
          echo '==> Publish Result'
          jq '.' <<< $result
      - name: Save publish result
        uses: actions/upload-artifact@v1
        with:
          name: published
          path: result.json

This

- uses: prisma-labs/dripip
  with:
    npm_token: ${{ secrets.NPM_TOKEN }}    

For handling the artifacts part, refer to this issue which mentions more actions/upload-artifact#62.

In lieu of #58 we might be able to workaround using forks. If we really want to avoid the sdk work for now.

1. New requirement discovered for this issue from Handling GITHUB_TOKEN now with changelog support #71. CI now needs GITHUB_TOKEN.

2. Another thing we need to cover, hit this today (don't know why I didn't hit it before...) RFC: fetch-depth: 1 and not cloning tags are dangerous defaults actions/checkout#217; specifically the part about needing to pull in all git tags (depth: 0 I knew about from before).

Note the solution for pulling git tags has some discussion here actions/checkout#206 / actions/checkout#206 (comment)
