A correction fixes a fact that was wrong: a number, a name, a date, a quote or an attribution. An update adds something material that happened after publication. Both are dated, kept on the story & listed here. We do not silently rewrite the substance of a finding. To report one, send the page & the supporting information. Typos & formatting fixes are not listed.
No corrections have been needed so far. When one is, it appears here with the date & what changed.
