This GitHub Action is designed to automatically create a release of the Blender add-on and upload .zip file to it. Action requires the add-on to be previously build and uploaded as artifact using Blender Addon Build action or Upload Artifact action.

• Automated zipping of Blender Addon artifacts.
• Dynamic naming convention based on the stage of release and other inputs.
• Supports multiple release stages including: alpha, beta, rc (release candidate), and gold (final public release).

Use the Blender Addon Release action in your GitHub workflow after the Blender Addon Build or Upload Artifact action. Here's a basic example:

name: Release

on:
  pull_request:
    branches: [ '**' ]
  workflow_dispatch:
    inputs:
      version:
        description: 'version'
        required: true
        default: '1.0.0'

permissions:
  contents: write

jobs:
  Build:
    runs-on: ubuntu-latest
    steps:        
      - name: Build addon
        uses: blenderkit/blender-addon-build@main
        with:
          name: sample-addon
          exclude-files: ".git;.github;README.md"

  Release:
    runs-on: ubuntu-latest
    needs: Build
    steps:
      - name: Release addon
        uses: blenderkit/blender-addon-release@main
        with:
          artifact_name: sample-addon
          release_name: SampleAddon
          version: ${{github.event.inputs.version}}

It's important to note that this action is designed to be used in conjunction with the Blender Addon Build action. Make sure to run the Build job before the Release job. Or run custom build job and finish it by uploading the zip file as artifact using the Upload Artifact action.
