# NetBSD-8 release notes items #

Below list needs to be expanded about ARM, MPSAFE networking 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
