The major changes are: + 4Gb (24XX) card support + Rewritten fabric and loop evaluation code + New f/w sets The 4Gb changes required major rototilling, which caused a rewrite of fabric and loop eval code. The latter can now be set up to tune for dynamic device arrival/departure if the framework is set up for it, or to be firm about waiting for devices. Testing has been principally on amd64, i386 and sparc64 and seems to not have broken things for me.
