This adjustment in Linux Mint 19 allows users to install kernel updates along with other patches. Previously, after the user installed the new kernel, the old kernel will continue to exist unless the user enters the Update Manager and manually deletes them one by one. This causes the user to receive a notification that the boot sector is full after installing the new kernel. Now, there is a button in the kernel manager that "delete the old kernel", which is convenient for the user to select the old kernel to be deleted and delete it in batches.
22 new wallpapers have also been introduced in the Linux Mint 19.1 Beta release, with Mint-Y, Mint-Y-Dark and Mint-Y-Darker now available in Aqua, Blue, Brown, Grey, Orange, Pink, Purple, Red, Sand.
