Example workflow - create a release

On every push to a tag matching the pattern v*, create a draft release with changelog:

on:
  push:
    tags:
      - 'v*'

name: Create Release

jobs:
  release:
    name: Create Release
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
        with:
          fetch-depth: 0

      - name: Get Previous Tag
        run: |
          PREV_TAG=$(git describe --abbrev=0 --tags "${{ github.ref }}^")
          echo "::set-env name=baseRef::$PREV_TAG"

      - name: Generate Changelog
        id: generate_changelog
        uses: nblagoev/pull-release-notes-action@v1
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} # This token is provided by Actions, you do not need to create your own token
        with:
          base-ref: ${{ env.baseRef }}
          head-ref: ${{ github.ref }}

      - name: Create Release
        uses: actions/create-release@v1
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          tag_name: ${{ github.ref }}
          release_name: Release ${{ github.ref }}
          body: ${{steps.generate_changelog.outputs.result}}
          draft: true

This workflow will generate a changelog from the pull requests merged between the current and the previous tag. Then it will create a Draft Release with the changelog as body.
