calibre Auto-Updater is a GUI plugin designed to streamline the update process of calibre directly from the interface. Instead of manually checking the website or opening a separate terminal, this plugin automates the download and launch of the official installer across different operating systems.

Main Features
One-Click Update: Triggers the official update process.

Safety First: Automatically closes calibre before updating to prevent database corruption or file-locking issues.

Multi-platform Support: Intelligent behavior for Linux, Windows, and macOS.

I18n Ready: Prepared for translations (currently English base).

Important: Compatibility & Behavior
This plugin is designed exclusively for standard binary/fixed installations.

Critical Notes:
Linux Users: Upon confirmation, calibre will close immediately and your default terminal will open to run the official script. Asking for your root password. This is required to overwrite system files while they are not in use.

Windows Users: The plugin downloads the official .msi installer to your Desktop and launches it.

Flatpak, AppImage & Portable Versions: These formats are not supported for automatic updates. If you use these, the plugin will notify you that a manual update is required.
