FreeBSD 13.1 is now available, notable as it comes in both big-endian and little-endian flavours depending on how you swing (as well as 32-bit ports for Power Macs and the AmigaOne A1222). The biggest change in this version is that 13's shift to the PowerPC ELF ABIv2 makes it binary-incompatible with 12.x (so you may need to rebuild or relink; the release notes also suggest doingkldxref /boot/kernel
after successful installation or upgrade). However, there are also fixes for the bootloader on the LE port, OpenSSL performance improvements, a serial console fix for the BE port, a fix for running FreeBSD with HPT superpages enabled on QEMU with TCG (if you're trying before you're buying), and — particularly of relevance to those of us on OpenPOWER hardware — a fix for the AST2500 console on bootup with recent OpenBMC firmware. It's a big update but one that makes OpenPOWER an even better citizen on FreeBSD (now if only NetBSD would get with the program, because at this point it's just embarrassing).
