   ## 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
