The Linux kernel version 4.11 has been released on 30/April/2017.
From the lwn.net:
Some headline features in 4.11 include: a new perf ftrace command restarting the work of better integrating the perf and ftrace subsystems, I/O scheduling support for the multiqueue block subsystem, journaling for device-mapper RAID 4/5/6 volumes, SipHash support, some swapping scalability improvements, a new LZ4 compression implementation, the new statx() system call, and more. As always, see the KernelNewbies 4.11 page for lots of details.
