An anonymous reader writes: The first release candidate of Linux 4.1 is now available. Linus noted, "The merge window is pretty normal in terms of what got merged too. Just eyeballing the size, it looks like this is going to fit right in — while 4.0 was a bit smaller than usual, 4.1 seems to be smack dab in the middle of the normal range for the last couple of years." There are numerous new features in Linux 4.1, like Xbox One controller force feedback support, better Wacom tablet support, Intel Atom SoC performance improvements, Radeon DisplayPort MST support, EXT4 file-system encryption, ChromeOS Lightbar support, and ACPI for 64-bit ARM, among other additions. However, KDBUS wasn't accepted for Linux 4.1.
