The PS3 version was patched to 1.06 on Thursday.

Anyone know what it does?

I'm going to assume it is all of the above, link is right here.

"First of all - it updates RB1 so you will still be able to purchase DLC from the Rock Band store. Downloading this patch is required if you'd still like to do that.

Second - Lowers the threshold on gold stars making it easier/possible to gold star songs. This won't affect leaderboards as it only affects the threshold, not the score.

Third - Lately a few songs have had unhittable notes. This should be fixed now.

Lastly - It will allow you to export your songs from the RB1 disc to the hard drive for play in Rock Band 2. Official language follows for this feature-"

That's an old patch. ^

My game updated a few days ago too (Xbox 360).

Yeah, all that stuff came out a while ago, Karmum. If I recall correctly that was all in the 1.04 patch. Thanks for trying to hunt the details down though!

Thats what I was wondering....fix bugs?
