… Last year, the IRS made final proposed Regulations (RIN 1545-BF96, Regulations Governing Practice Before the Internal Revenue Service, downloads as a pdf) that made changes to Circular 230. You can read the amendments to 31 CFR part 10 here.

The “covered opinion” rules in section 10.35 have been eliminated and replaced by more practical, flexible, reason-based requirements for written advice in section 10.37. Among the consequences of the changes is that the Circular 230 disclaimer that now appears at the bottom of many emails and on memos can and should be eliminated.
