This PHP class provides a solution for developers who host their plugins on GitHub but want to offer users a familiar, automatic update process. It integrates directly into a plugin's code to check for new releases on GitHub and install them from the WordPress admin panel.

• Automatic Update Checks: The class periodically checks your specified GitHub repository for new tagged releases, alerting users when an update is available.
• One-Click Installation: Users can install updates directly from their WordPress admin dashboard with a single click, without manually downloading files.
• Version Source Flexibility: It can read the new version number from either the plugin's main file header or a specified readme file, providing configuration options.
• Private Repository Support: Includes the ability to connect to private GitHub repositories by using an access token for authentication.
• Backwards Compatibility: Maintains support for older methods of defining the version while adopting newer standards, ensuring it works with existing plugin setups.
