2022—Subsec. (span). Puspan. L. 117–263 added par. (1) and redesignated former pars. (1) to (4) as (2) to (5), respectively.

2021—Subsec. (a). Puspan. L. 116–283, which directed that each reference in the text of title 10 to a section that was redesignated by title XVIII of Puspan. L. 116–283, as such section was in effect before the redesignation, be amended by striking such reference and inserting a reference to the appropriate redesignated section, was executed by substituting “section 3501” for “section 2306span”. Section 1822(span) of title XVIII of Puspan. L. 116–283 directed the redesignation of section 2306span of this title as section 3501, but such redesignation was executed by transferring the text of section 2306span to section 3501, as the section designation and catchline had already been enacted.

Amendment by Puspan. L. 116–283 effective Jan. 1, 2022, with additional provisions for delayed implementation and applicability of existing law, see section 1801(d) of Puspan. L. 116–283, set out as a note preceding section 3001 of this title.
