Theo de Raadt has announced the release of OpenBSD 4.2: "We are pleased to announce the official release of OpenBSD 4.2. This is our 22nd release on CD-ROM (and 23rd via FTP). We remain proud of OpenBSD's record of more than ten years with only two remote holes in the default install. As in our previous releases, 4.2 provides significant improvements, including new features, in nearly all areas of the system. New and extended platforms: PCIe UltraSPARC IIIi machines like the V215 and V245; AlphaServer 1200 and 4100. Install and upgrade process changes: new install method - for the most popular architectures, the FTP sites have a 200MB install ISO file, which contains the base set, permitting non-network installs; allow the specification of an NTP server during installation. Improved hardware support, including native Serial ATA support...." Read the detailed release announcement and visit the OpenBSD 4.2 page for a full list of new features.

BSD Release: OpenBSD 6.5 |
|
OpenBSD is an open source operating system designed with the goals of being simple, secure and offering correct documentation. The project's latest release is OpenBSD 6.5 offers Clang on the mips64 architecture, improves wireless performance, and the unveil() function now handles protecting filesystem assets above the process's directory. "Installer improvements: rdsetroot(8) (a build-time tool) is now available for general use. During upgrades, some components of old releases are deleted. Security improvements: unveil(2) has been improved to understand and find covering unveil matches above the working directory of the running process for relative path accesses. As a result many programs now can use unveil in broad ways such as unveil("/", "r"). unveil(2) no longer silently allows stat(2) and access(2) to work on any unveiled path component." The new release also offers LibreSSL 2.9.1 and OpenSSH 8.0 which include security improvements. Further details can be found in the project's release notes and in the changelog.

BSD Release: OpenBSD 6.4 |
|
OpenBSD is a security-focused operating system with a design that emphasises correct code and accurate documentation. The project has released OpenBSD 6.4 which includes many driver improvements, a feature which allows OpenSSH's configuration files to use service names instead of port numbers, and the Clang compiler will now replace some risky ROP instructions with safe alternatives. Perhaps the most interesting feature is the unveil() system call which allows applications to sandbox themselves, blocking their own access to the file system. This is especially useful for programs which operate on unknown data which may try to exploit or crash the application: "New unveil(2) system call to restrict file system access of the calling process to the specified files and directories. It is most powerful when properly combined with privilege separation and pledge(2)." Other security improvements include: "Implemented MAP_STACK option for mmap(2); new RETGUARD security mechanism on amd64 and arm64 - use per-function random cookies to protect access to function return instructions, making them harder to use in ROP gadgets...." Further details can be found in the project's release notes and in the changelog. Download: amd64/install64.iso (343MB, SHA256, signature), i386/install64.iso (324MB, SHA256, signature). |

BSD Release: OpenBSD 6.3 |
|
OpenBSD is a security-focused operating system with a focus on correct code and accurate documentation. The project has released OpenBSD 6.3 which introduces SMP support on the ARM64 architecture, includes ISO support in the virtual machine daemon (vmd) and makes memory allocation more efficient. There have also been several updates to the LibreSSL and OpenSSH secure communication tools: "LibreSSL 2.7.2 - Added support for many OpenSSL 1.0.2 and 1.1 APIs, based on observations of real-world usage in applications. These are implemented in parallel with existing OpenSSL 1.0.1 APIs - visibility changes have not been made to existing structs, allowing code written for older OpenSSL APIs to continue working. Extensive corrections, improvements, and additions to the API documentation, including new public APIs from OpenSSL that had no pre-existing documentation. Added support for automatic library initialization in libcrypto, libssl, and libtls. Support for pthread_once or a compatible equivalent is now required of the target operating system. As a side-effect, minimum Windows support is Vista or higher." The release announcement has more information.

BSD Release: OpenBSD 6.2 |
|
OpenBSD is a lightweight operating system designed with code correctness and security in mind. The project has released OpenBSD 6.2 which features many new drivers, particularly for the ARM architecture, and network packet handling performance improvements. Some key features have been added to the system installer too, including checking for security updates on the system's first boot: "Installer improvements: The installer now uses the Allotment Routing Table (ART). A unique kernel is now created by the installer to boot from after install/upgrade. On release installs of architectures supported by syspatch, "syspatch -c" is now added to rc.firsttime. Backwards compatibility code to support the 'rtsol' keyword in hostname.if(5) has been removed. The install.site and upgrade.site scripts are now executed at the end of the install/upgrade process. More detailed information is shown to identify disks. The IPv6 default router selection has been fixed. On the amd64 platform, AES-NI is used if present." Further information on OpenBSD 6.2 can be found in the project's release notes. Download (pkglist): amd64/install62.iso (330MB, SHA256, signature), i386/install62.iso (320MB, SHA256, signature). |

BSD Release: OpenBSD 6.1 |
|
The OpenBSD developers have announced the availability of a new stable release of their security-oriented operating system. The new release, OpenBSD 6.1, introduces bug fixes, several new or improved hardware drivers and security enhancements to the system installer. "We are pleased to announce the official release of OpenBSD 6.1. As in our previous releases, 6.1 provides significant improvements, including new features, in nearly all areas of the system. The installer now uses privilege separation for fetching and verifying the install sets. Install sets are now fetched over an HTTPS connection by default when using a mirror that supports it. The installer now considers all of the DHCP information in file name, boot file-name, server-name, tftp-server-name, and next-server when attempting to do automatic installs or upgrades. The installer no longer adds a route to an alias IP via 127.0.0.1, due to improvements in the kernel routing components." Additional details on the OpenBSD 6.1 release can be found in the project's release announcement and a complete list of changes since version 6.0 can be found in the project's changelog.
