Default NetBSD 7.2 Released


NetBSD 7.2 released (August 29, 2018)

The NetBSD Project is pleased to announce NetBSD 7.2, the second feature update of the NetBSD 7 release branch. It represents a selected subset of fixes deemed important for security or stability reasons, as well as new features and enhancements.
General Security Note
The NetBSD 7.2 release is a maintenance release of the netbsd-7 branch, which had it's first major release, NetBSD 7.0 in September 2015. A lot of security features have been added to later NetBSD versions, and for new installations we highly recommend using our latest release, NetBSD 8.0 instead.
Some highlights of the 7.2 release are:

Support for USB 3.0.
Enhancements to the Linux emulation subsystem.
Fixes in binary compatibility for ancient NetBSD executables.
iwm(4) driver for Intel Wireless 726x, 316x, 826x and 416x series added.
Support for Raspberry Pi 3 added.
Fix interrupt setup on Hyper-V VMs with Legacy Network Adapter.
SVR4 and IBCS2 compatibility subsystems have been disabled by default (besides IBCS2 on VAX). These subsystems also do not auto-load their modules any more.
Various USB stability enhancements.
Numerous bug fixes and stability improvements.
When you see a good move, look for a better one.

What are noticeably absent are mitigations for Spectre/Meltdown that were implemented in NetBSD 8.0. From the NetBSD 8.0 release announcement:
Specific to i386 and amd64 CPUs:

Meltdown mitigation: SVS (Separate Virtual Space), enabled by default.
SpectreV2 mitigation: retpoline (support in gcc), used by default for kernels. Other hardware mitigations are also available.
SpectreV4 mitigations available for Intel and AMD.
PopSS workaround: user access to debug registers is turned off by default.
Lazy FPU saving disabled on vulnerable Intel CPUs ("eagerfpu").
SMAP support.
Improvement and hardening of the memory layout: W^X, fewer writable pages, better consistency, better performance.
(U)EFI bootloader.
