Nothing has changed, as far as I can tell. In late 2016, The FCC enacted a new set of rules late last year that would override exemptions in 18 U.S. Code § 2511 and prevent U.S ISPs from gathering or selling data they would have otherwise been legally able to gather and sell. These privacy rules were set to come into effect later this year (2017).
SJ Res 34 was a congressional review of that rule. The result if which is that the FCC rule that was proposed late last year- that is, 2016 - will never go into effect.
Part of that US Code effectively exempts from wiretap law packets and data addressed to you- that is, it's not a violation of wiretap laws if you record and gather data that is directly addressed to your server. The new Rule was set to effectively prevent ISPS from using that exemption going forward to gather or sell any information.
The exemption only really covers DNS lookups. Intercepting and recording actual web traffic is still illegal under the wiretap laws, and for the most part always has been. (Not that it matters quite so much with the push for https everywhere)
