🚀OpenBSD 8.0 Released with 512G Kernel Address Space
512G Kernel Address Space in OpenBSD 8.0
TL;DR
OpenBSD 8.0, the 61st release, introduces a 512G kernel address space, random pmap(9) direct map placement, and hibernate support for arm64. Key improvements include faster swap encryption and support for Intel Arc A-Series graphics cards.
OpenBSD 8.0, the 61st release, was just dropped with a major update to the kernel address space, expanding it to 512G from 4G. This is a big deal for developers working with large-scale applications that require extensive memory. The new address space, combined with improvements like faster swap encryption and hibernate support for arm64, means OpenBSD is now better equipped to handle complex workloads. The release also includes support for Intel Arc A-Series graphics cards and various bug fixes, making it a solid choice for those needing robust security and performance.
Key Points
