According to EWTN (I didn't watch the proceedings), there are two pieces of news on the the proposed music document that had been scheduled to be considered at the Fall USCCB meeting: 1) it has been downgraded from particular law to advisory, which means that it will not have the same binding status and will not require Rome's approval, and 2) it has been otherwise withdrawn because there were 100 pages of proposed changes and there was no way it could be tackled at the USCCB meeting.
Please correct this post if it is inaccurate in any respect. I'm only reporting what the news anchor said as best as I can understand it.
