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 9.3 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.
Complete source and binaries for NetBSD 7.2 are available for download at many sites around the world. A list of download sites providing FTP, AnonCVS, SUP, and other services may be found at https://www.NetBSD.org/mirrors/. We encourage users who wish to install via ISO or USB disk images to download via BitTorrent by using the torrent files supplied in the images area. A list of hashes for the NetBSD 7.2 distribution has been signed with the well-connected PGP key for the NetBSD Security Officer: https://cdn.NetBSD.org/pub/NetBSD/security/hashes/NetBSD-7.2_hashes.asc
NetBSD is free. All of the code is under non-restrictive licenses, and may be used without paying royalties to anyone. Free support services are available via our mailing lists and website. Commercial support is available from a variety of sources. More extensive information on NetBSD is available from our website:
Below is an abbreviated list of changes in this release. The complete list of changes since NetBSD 7.1 can be found in the CHANGES-7.2 file in the top level directory of the NetBSD 7.2 release tree.

- Prevent unrestricted userland access to I/O ports in XEN.
- carp(4): fix link state handling.
- ipf(4): fragment and package state are separate, the user needs to specify both "keep state" and "keep frags" to get the same behaviour as before.

- resize_ffs(8): Fixed overflow errors which could lead to superblock corruption on large filesystems.
- Update root.cache to 2017102400.
- httpd(8): fixed errors when executing cgi scripts via the -C mechanism.

NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent for use in both production and research environments, and the source code is freely available under a business-friendly license. NetBSD is developed and supported by a large and vibrant international community. Many applications are readily available through pkgsrc, the NetBSD Packages Collection.
The NetBSD Foundation was chartered in 1995, with the task of overseeing core NetBSD project services, promoting the project within industry and the open source community, and holding intellectual property rights on much of the NetBSD code base. Day-to-day operations of the project are handled by volunteers.
As a non-profit organization with no commercial backing, the NetBSD Foundation depends on donations from its users, and we would like to ask you to consider making a donation to the NetBSD Foundation in support of continuing production of our fine operating system. Your generous donation would be particularly welcome to help with ongoing upgrades and maintenance, as well as with operating expenses for the NetBSD Foundation.
