GitHub doesn't provide a built-in way to send notifications if a field of the project is changing. This GitHub Action aims to address this by allowing you to identify the change of the release field within a central GitHub project.

This GitHub Action allows you to identify changes in a central GitHub project on opened issues. If the release field changes then
the assignees of the issue will be informed via comment.

Before you can start using this GitHub Action, you'll need to ensure you have the following:

1. A GitHub repository where you want to enable this action.
2. A GitHub project board with custom "Release" field added.
3. "Release" field should be "Single select" type.
4. A Token (Classic) with permissions to repo:*, read:user, user:email, read:project

To set up release change comment notifications, you'll need to create or update a GitHub Actions workflow in your repository. Below is an example of a workflow YAML file:

name: Notify for release change

# Runs every minute
on:
  schedule:
    - cron: '* * * * *'
  workflow_dispatch:

jobs:
  notify_for_release_change:
    runs-on: self-hosted

    steps:
      # Checkout the code to be used by runner
      - name: Checkout code
        uses: actions/checkout@v3

      # Check for release changes
      - name: Check for release changes
        uses: emily-lambrou/release_project-field_changes@v1.3
        with:
          dry_run: ${{ vars.DRY_RUN }}           
          gh_token: ${{ secrets.GH_TOKEN }}      
          project_number: ${{ vars.PROJECT_NUMBER }} 
          enterprise_github: 'True'
          repository_owner_type: organization
