Only needs to be expanded about ARM now.

# NetBSD-8 release notes items #

Below list needs to be expanded about ARM changes.  
Then expanded to be readable by an average technically inclined person.  
Then reordered for most cool things on top.

* PaX MPROTECT (W\^X) memory protection enforced by default on architectures with fine-grained memory protection
* PaX ASLR in some archs, MKPIE default for userland  
XXX list of archs
* SSP/FORTIFY default for userland and packages.  
XXX is SSP / MKPIE new to userland?
* In-kernel audio mixer
* Real-Time Signals
* Synchronize Machine Independent features in ptrace(2) with Linux and FreeBSD
* Improved C11 feature completeness (added missing headers, implemented functions)
* ext4 enhanced read-only support
* nc(1) imported from OpenBSD
* sys_info a new script to return version information for system libraries and utilities
* added intrctl(8) interrupt distribution control utility.
* added can(4) socketcan implementation, a socket layer for CAN busses
* removed MKCRYPTO option and always include cryptography
* dc(1) import from OpenBSD (and replace the GNU version)
* Endian-Independent disklabel support DISKLABEL_EI
* pthread_dbg(3) removed from the base distribution
* improved compatiblity of NetBSD curses(3) with ncurses
* added libpanel(3) compatible with ncurses libpanel
* added ipsecif(4) for route-based VPNs
* made part of the network stack MP-safe
  * NET_MPSAFE kernel option is required to try
  * Only the components listed below are MP-safe for now

Custom:

* USB system rework. added USB3 support.

The following networking components and drivers have been made MPSAFE:  

* Device drivers
  * vioif(4)
  * vmx(4)
  * wm(4)
  * ixg(4)
  * ixv(4)
* Layer 2
  * Ethernet (if_ethersubr.c)
  * bridge(4)
  * Fast forward (ipflow)
* Layer 3
  * Almost done but some components are still non-MP-safe
* Interfaces
  * gif(4)
  * ipsecif(4)
  * l2tp(4)
  * pppoe(4)
  * tun(4)
  * vlan(4)
* Packet filters
  * npf(7)
* Others
  * bpf(4)
  * ipsec(4)
  * opencrypto(9)
  * pfil(9)

* Reproducible build (link to blog)
* Dynamic tracing (DTrace) for kernel code (link to guide/intro)


amd64, i386:
