FreeBSD is phasing out support for 32-bit platforms in upcoming major releases, with armv6, i386, and powerpc architectures likely to be excluded in FreeBSD 15.0 and armv7 in FreeBSD 16.0. Support for executing 32-bit binaries on 64-bit kernels will continue for the foreseeable future. The decision is based on the decreasing market presence and developer resources for 32-bit platforms, with focus shifting to 64-bit systems. While new 32-bit platforms will not be added, support may be extended with demand and increased resources. More information can be found in the release notes for FreeBSD 14.0.
