"The latest release of FreeBSD contains a lot of crucial under-the-hood changes - and drops 32-bit support on both x86 and POWER, although ARM-v7 survives. FreeBSD 15.0-RELEASE arrived this week, the latest release of the Unix world's leading alternative to Linux. As well as numerous bug fixes and upgrades to many of its components, the major changes in this version are reductions in the number of platforms the OS supports, and in how it's built and how its component software is packaged."
"The venerable 32-bit hardware platforms i386, armv6, and 32-bit powerpc have been retired. 32-bit application support lives on via the 32-bit compatibility mode in their respective 64-bit platforms. The armv7 platform remains as the last supported 32-bit platform. We thank them for their service. Now FreeBSD supports five CPU architectures - two Tier-1 platforms, x86-64 and AArch64, and three Tier-2 platforms, armv7 and up, powerpc64le, and riscv64."
"Another significant change is that this is the first version built under the new pkgbase system, although it's still experimental and optional for now. If you opt for a pkgbase installation, then the core OS itself is installed from multiple separate software packages, meaning that the whole system can be updated using the package manager. Over in the Linux world, this is the norm, but Linux is a very different beast."
FreeBSD 15.0-RELEASE reduces platform support and changes build and packaging methods while including numerous bug fixes and component upgrades. The release retires 32-bit builds for i386, armv6, and 32-bit powerpc, leaving armv7 as the sole supported 32-bit platform with compatibility modes on 64-bit hosts. Supported architectures now include Tier-1 x86-64 and AArch64 and Tier-2 armv7 and up, powerpc64le, and riscv64. An experimental, optional pkgbase system allows the core OS to be installed from multiple packages so the entire system can be updated through the package manager. The shift aligns with broader moves away from x86-32.
