There was Altivec in 7.2-RELEASE as well, and it is quite stable. Ports that know about it will use it by themselves, or you can define something like CPUTYPE=7450 in make.conf to have the compiler try to autovectorize things. 8.0 has a bunch of other new PowerPC features like audio, SMP, G5 support, ATA DMA, ADB keyboard and mouse support, some basic power management, including cpufreq, etc. Hopefully it will be a better experience than 7.2 -- the big architectural differences between 8.0 PowerPC and 7.0 PowerPC have made it difficult to MFC things for some time. -Nathan
