            This release includes the following packages:
            
            • linux-headers  
            • linux-image  
            • linux-libc-dev
            
            **Configurations:**
            - **Vanilla:** The default configuration taken from a recent Debian kernel config and applied to the latest upstream kernel.
            - **VM:** An optimized configuration for virtual environments (VMware, VirtualBox, Hyper-V, Xen, KVM) with unnecessary drivers removed.

            **Automated Installation:**
            For convenient installs, use our Packagecloud repository:
            
            ```bash
            curl -s https://packagecloud.io/install/repositories/debian-kernels/buster/script.deb.sh | sudo bash
            ```
            
            Then install the desired kernel packages using your package manager.
            
            Enjoy your new kernel!
