OpenBSD 8.0 has been released, marking the project’s 61st release since its inception in 1996. Known for its security-conscious approach, OpenBSD continues to deliver top-notch features with each release. With the latest version, OpenBSD 8.0 brings a host of new features and enhancements to improve performance and compatibility. Here are some highlights from the release:
Intel Arc Support and More VRAM
One of the significant additions in OpenBSD 8.0 is the support for Intel Arc A-series (DG2/Alchemist) graphics cards. This update allows for better compatibility with modern GPUs and facilitates mapping of more than 4GB of data, including VRAM.
Expanded Address Space for AMD64
With the latest release, AMD64 systems can now utilize up to 512GB of kernel virtual address space, a significant boost from the previous limit of 4GB. This enhancement opens new possibilities for applications that require large memory mappings.
Hibernation Support on ARM64
OpenBSD 8.0 also introduces hibernation support for ARM64 systems, providing users with more flexibility and power-saving options on compatible devices.
RPKI and RISC-V Improvements
The new version includes additions like RPKI support in the router daemon (rtrd(8)) and enhanced support for RISC-V architecture, including kernel support for “V” vector extensions and advanced interrupt architectures.
Wireless Networking Enhancements
Users will benefit from improved wireless network driver support, including 802.11n and 40 MHz channels in the qwx(4) wireless driver, enhancing connectivity options for OpenBSD users.
Virtualization Capabilities
OpenBSD 8.0 now supports up to 64 virtual CPUs per guest virtual machine, catering to users requiring high-performance virtualization solutions.
Security Updates
Security remains a top priority, with significant updates to LibreSSL 4.4.0 and OpenSSH 10.6 included in this release, ensuring the integrity and confidentiality of user data.
Discontinued Support
Please note that OpenBSD 8.0 discontinues support for the Loongson architecture and the clan 22 compiler. Users relying on these components should take note of the changes in the latest release.
For a detailed list of all changes and updates in OpenBSD 8.0, refer to the official release announcement.
Stay tuned for more exciting developments from the OpenBSD project as they continue their commitment to security, performance, and innovation in the world of operating systems.
