From the release notes, it appears this may be the last release with i386 / 32-bit Intel x86 (as well as 32-bit armv6 and PowerPC) support.
“FreeBSD 15.0 is not expected to include support for 32-bit platforms other than armv7. The armv6, i386, and powerpc platforms are deprecated and will be removed. 64-bit systems will still be able to run older 32-bit binaries.“
