First release. It covers every U.S. county area in the National Risk Index, including those absent from FEMA plan data, plus every Vermont town. There is no earlier release to compare with, so no changes are listed; from the next release on, this page lists what changed (plan status changes, new declarations, new Storm Events records) and each packet's "What changed" box compares with the prior release.
