这版增加了 powerpc64 平台。
另外一些安装的变化：
- Installer improvements:
- On systems with multiple root disks, the installer will upgrade the disk with auto_upgrade.conf present when the upgrade was initiated by sysupgrade(8).
- Changed install images called *.fs to *.img to accommodate some UEFI bootloaders.
- Forced long-names on msdos filenames for installboot on most 32-bit architectures.
- Converted macppc, octeon and loongson to use machine-independent installboot.
