 ## Release notes (top)  
   
 * Support for Aarch64 (ARM 64-bit) machines.    
   The aarch64 port should work on many Allwinner machines, SBSA/SBBR compatible servers.    
   It supports multiple processors, including in a big.LITTLE configuration, ACPI and UEFI.    
   It uses a single kernel to support a large amount of boards with the help of ACPI+UEFI or FDT.  
 * Updated graphical acceleration support from Linux 4.4.    
   Intel graphics including Kaby Lake. Nouveau and radeon.  
 * nvmm(4) - hardware-accelerated virtualization, currently supporting x86-SVM.    
   a patched QEMU package exists that utilizes this.    
   XXX make statement reflect reality at the time of the release.  
 * KASLR - kernel address stack randomization.    
   Note that the default kernel does not use this option.    
   XXX maybe link for how to use it, then.  
 * kASAN - kernel address sanitizer build option, to detect memory access violations, for x86 and aarch64.  
 * kUBSAN - kernel undefined behaviour sanitizer.  
 <!-- XXX kamil please list more things about micro-UBsan, MKLIBCSANITIZER, etc. -->  
 * KLEAK - detects kernel memory leaks.  
 * bwfm(4) - Broadcom Full-MAC wireless driver at PCI and USB (from OpenBSD)  
 * ena(4) - Amazon.com Elastic Network Adapter (from FreeBSD)  
 * GCC leak sanitizer support  
   
 ARM hardware support:  
   
 * Support for running on Amazon AWS ARM instances.  
 * Support for nVidia Tegra X1 SoCs  
 * Support for Pine64 SoCs, including pinebook  
 <!-- XXX list more? -->  
   
 misc:  
   
 * newsmips NWS-4000 support  
   
 The following components have been removed:    
   
 * ISDN support and related drivers (daic(4), iavc(4), ifpci(4), ifritz(4), iwic(4), isic(4))  
 * Network ATM protocol code and related drivers (midway(4))  
 * Remote NDIS API compatibility (for running unmodified older Windows drivers)  
 * SVR4 binary compatibility code  
 * VM86  
 * IPKDB (remote debugger)  
 * NetOctave NSP2000 security accelerator, n8(4)  
   
 ## Release notes (next)  
   
 * GCC 6.5.0  
 * GDB 8.0.1  
 * LLVM 7.0.0  
 * OpenSSL 1.1.1a  
 * OpenSSH 7.8  
 * sqlite 3.26.0
