[Atanvarno]

In 2000, IAAF rule 260.18a (formerly 260.6a) was amended, so that "world records" (as opposed to "indoor world records") can be set in a facility "with or without roof." This rule was not applied retroactively,[6] and has, thus far, only affected the men's and women's pole vault, and women's 2,000 m.
