Calibre 7.16.0
New features:
- Add a driver for the new 2024 Tolino devices. They use a modified version of the Kobo firmware, so they are detected as Kobo devices.
- Various news recipes now have the ability to download past issues, accessible via the Advanced tab in the Schedule news dialog

Fixed:
- ONLY if you use the calibre Content server, you should update calibre as soon as possible
- If you do not know what the Content server is, you do not use it, and these do not apply to you. If you have set a password to access the Content server that you have not shared with anyone, these do not affect you. A remote code execution bug in the Content server introduced in calibre version 6.9.0 (released on 2022-11-25) means that anyone with access to the server also has access to the rest of the computer the server is running on. If you are using a password to protect access to the server only people that know the password can gain access via the bug. Thanks to STAR Labs (https://starlabs.sg) for finding these vulnerabilities.

- Content server: Fix an XSS vulnerability in one endpoint
- Only relevant if you embed the calibre server within a larger server, it means attackers who can convince users to click on a specially crafted link, can run JavaScript code with the same origin as the larger server calibre is embedded in.
