Linux Kernel 4.1.1 was released earlier this week with a host of improvements and new features making it the most advanced and stable version of the 4.x LTS series.
Greg Kroah-Hartman, who released this latest version, recommended existing users of the 4.1 kernel series upgrade immediately. As the Linux Kernel 4.1.1 is an LTS version, every week a new version of Kernel 4.1.x will be released.
According to the change log, there are Brodwell-specific enhancements as well as support for ATOL FPrint fiscal printers. Also, an overflow warning with 32-bit binutils has been removed.
In addition, starting with the 4.x series, you do not have to reboot your system to update your Linux Kernel Version as a result of the implementation of the long-awaited Life Patching feature.
