The new ISOs for Debian 12.7 and 11.11 bring together a variety of updated packages, ensuring your system is up-to-date from the get-go. Some of the significant packages updated in these releases include:

Calibre: Improved performance and bug fixes for this popular e-book manager.

Linux Kernel: Enhanced security and hardware compatibility.

Numpy: Updates to this essential scientific computing library.

Shim: A critical update concerning Secure Boot compatibility.

Systemd: Better system and service management with new bug fixes.

Comparisons with Previous Releases

When comparing Debian 12.7 and 11.11 to their predecessors, the key difference lies in the inclusion of the latest security and software updates. These point releases are primarily about stability and security, ensuring that your system is protected from the latest vulnerabilities while also benefiting from improved package performance.

For Debian 12 users, the updates are a continuation of the improvements introduced in the main release, focusing on refining and enhancing system stability. On the other hand, Debian 11.11 represents one of the final updates before the Debian Long Term Support (LTS) team takes over, ensuring that security updates continue for Debian 11 users until August 2026.

Secure Boot Issue: A Closer Look

One of the more significant issues flagged in the Debian 11.11 update revolves around Secure Boot. The Debian team highlighted that shim 15.8, included with Debian 11.11, revokes signatures across older versions of shim in the UEFI firmware. This may result in older operating systems using shim versions before 15.8 being unable to boot if Secure Boot is enabled. This is especially important for users who dual-boot their systems with other operating systems.

What You Should Do:

If you're using multiple operating systems on the same hardware, you should temporarily disable Secure Boot before updating your other operating systems. This will prevent potential boot issues with those systems.

The Importance of Staying Updated

For users already running Debian, there’s no need to worry if you’ve kept your system updated. Your system is already on these point releases, and no additional action is required. However, if you have older installation media and plan to reinstall Debian, using the new ISOs will save you from downloading updates post-installation.
