I didnt mean to come off that way, so i appologize,
However, you hack your site at your own risk and time, and between 3.0.0 RC4 > Gold there are tons of small changes it was still a beta
between 3.0.0 and 3.0.1 there are more small changes.
Your welcome to try to go at it with a program like beyond compare and try to patch the files your self however, i highly recomend you spend your time re hacking, ive upgrade quite a few of my hacked sites from older versions to Gold or .1 with little down time and rehacking.
The price you pay for hacking is the time spent rehacking after each updarte you want to udpate to
