If no errors are reported, I will release it as the official version.

Calibre Updater 1.21.0

Almost automatic installation on all three systems

Windows: There's no need to go through the installation wizard (Next, Next...). Simply confirm the plugin's prompt and accept Windows' permission, which displays the official installer signed by Kovid Goyal. From there, the installation continues automatically, with a progress bar, and Calibre reopens automatically upon completion.

macOS: There's no need to drag Calibre to Applications or choose between keeping or replacing the previous version. The plugin safely replaces the application (if something goes wrong, the previous version remains intact) and reopens Calibre. It works on Macs with Apple Silicon and Intel processors.
Linux: It uses the official Calibre installer, displays progress in a log window, and notifies you if authentication fails.

Gracious Calibre shutdown

The plugin waits for Calibre to completely close before installing, without a fixed time limit. Thus, tasks that other plugins perform upon closing, such as backing up settings, finish before the installation begins, regardless of how long they take.

Previously, the Viewer and Book Editor ran in the background without notification. Now, the plugin notifies you if either is open and lets you choose: close them yourself (to save changes), have the plugin close them, or cancel.

It also notifies you if there are ongoing tasks, such as conversions, metadata downloads, or uploads to a device, and waits for them to finish or be canceled.

Change List

Automatic translation to the Calibre interface language, with a button to view the original English text. This can be disabled in the settings.

Beta Versions (Preview)

Beta versions are trial versions of Calibre that are installed manually. The plugin can notify you when a new version is available (option in the settings), but it never downloads or installs them. If you have a Beta version installed, the plugin doesn't modify it: it only notifies you when a newer stable version is released, and the update is up to you.

If you're using the regular version of Calibre, none of this affects you: the plugin only installs official stable versions.

Security and Diagnostics

Downloads with certificate verification and file integrity checks.

If something goes wrong, Calibre is never left partially installed: the installer or the downloads page opens to complete the installation manually.
A log file (calibre-updater.log) is saved in the downloads folder, which is useful for reporting problems.

The plugin also differentiates our calibre installation. Image 5

Translations:
Calibre Updater is available in English (the original language) and 18 other languages: Spanish, French, German, Italian, Czech, Slovak, Swedish, Serbian (Latin American), Russian, Ukrainian, Japanese, Chinese (China), Korean, Arabic, Dutch, Portuguese (Brazil), Galician, and Tamil. Spanish, French, German, and Italian were the first languages ​​translated for the plugin. The other fourteen were chosen based on the progress of Calibre's translation. All languages ​​with a fully translated Calibre interface and those with over 80% translation were included. This ensures that users of Calibre in these languages ​​also see the plugin in their own language, instead of encountering only the English menu within a translated program.
