Dear community users:

It is very happy that Linux Kernel 4.14.2 has officially released. This release includes support for bigger memory limits in x86 hardware (128PiB of virtual address space, 4PiB of physical address space); support for AMD Secure Memory Encryption; a new unwinder that provides better kernel traces and a smaller kernel size; a cgroups "thread mode" that allows resource distribution across the threads of a group of processes; support for the zstd compression algorithm has been added to Btrfs and Squashfs; support for zero-copy of data from user memory to sockets; better asynchronous buffered I/O support; support for Heterogeneous Memory Management that will be needed in future GPUs; better cpufreq behaviour in some corner cases; Longer-lived TLB entries by using the PCID CPU feature; asynchronous non-blocking buffered reads; and many new drivers and other improvements.
In order to make eveybody experiencing the change of the new kernel, we have officially packed the new kernel and tested to push it. If any community user would like to try it, he can upgrade to install Kernel 4.14.2.
