The version number. :)
Seriously, H. Peter Anvin, Chuck Crayne, and Keith Kanios have been hard at work! (a rising vote of thanks all around!)
Between 0.98.39 - the last 32-bit Nasm on SF (0.98.40 is available from Apple) - and 2.0rc1... lots!!! 64-bit support, Mac OSX support, improved speed, improved floating point constant handling, many bugs and potential "gotcha"s fixed. In short, the "complete rewrite" (nearly) that Nasm has needed for years.
Between 0.99.06 and 2.0rc1, mostly bugfixes... and the work is continuing. Get the full story here:

*Told* ya Nasm wasn't "dead"!
Best,
Frank
