Doesn't work for a push of many commits

[chermed]

When I push many commits, it just detect the changes from the last commit:

name: Test

on: push

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2.1.0
      - uses: jitterbit/get-changed-files@v1
        id: abc
        with:
          format: space-delimited
          token: ${{ secrets.GITHUB_TOKEN }}
      - name: Printing
        run: |
          echo "All:"
          echo "${{ steps.abc.outputs.all }}"
          echo "Added:"
          echo "${{ steps.abc.outputs.added }}"
          echo "Removed:"
          echo "${{ steps.abc.outputs.removed }}"
          echo "Renamed:"
          echo "${{ steps.abc.outputs.renamed }}"
          echo "Modified:"
          echo "${{ steps.abc.outputs.modified }}"
          echo "Added+Modified:"
          echo "${{ steps.abc.outputs.added_modified }}"

Example from stackoverflow (not mine)

This reply is kind of late, but maybe it will help someone out. You need to set the fetch-depth for actions/checkout to get the complete history.

# Number of commits to fetch. 0 indicates all history for all branches and tags.
# Default: 1
fetch-depth: ''

Example code:

- uses: actions/checkout@v2
  with:
    fetch-depth: 0
