First release candidate for NetBSD 9.0 available!

On behalf of the NetBSD project, it is my pleasure to announce the first
(and hopefully only) release candidate of NetBSD 9.0.

Many changes have been made since 8.1.  Here are a few highlights:

 - Support for Arm AArch64 (64-bit Armv8-A) machines, including
   "Arm ServerReady"  compliant machines (SBBR+SBSA)
 - Enhanced hardware support for Armv7-A
 - Updated GPU drivers (e.g. support for Intel Kabylake)
 - Enhanced virtualization support
 - Support for hardware-accelerated virtualization (NVMM)
 - Support for Performance Monitoring Counters
 - Support for Kernel ASLR
 - Support several kernel sanitizers (KLEAK, KASAN, KUBSAN)
 - Support for userland sanitizers
 - Audit of the network stack
 - Many improvements in NPF
 - Updated ZFS
 - Reworked error handling and NCQ support in the SATA subsystem
 - Support a common framework for USB Ethernet drivers (usbnet)

Since the start of the release process four months ago a lot of improvements
went into the branch - more than 500 pullups were processed!
This includes usbnet (a common framework for usb ethernet drivers), aarch64
stability enhancements and lots of new hardware support, installer/sysinst
fixes and changes to the NVMM (hardware virtualization) interface.
