OpenFEMA Changelog

All notable changes to OpenFEMA will be documented on this page. Each dataset or API release will indicate a release date, changes, and tags indicating the type of change. There may be data set releases that are not related to API version releases. Upcoming, unreleased changes will always appear at the top. Details regarding new features can be found in the OpenFEMA API documentation.

alert - warning

The OpenFEMA API and its associated services underwent a migration to cloud-based infrastructure on June 20. This change should ultimately result in the faster delivery of data and will allow us to expand functionality in the future.

No changes are required on your part to continue accessing OpenFEMA. We are issuing this notice for situational awareness only.

While extensive testing has been performed to ensure that data delivery and functionality remains unchanged from the previous platform, it is still possible that issues exist. We recommend that you monitor your use of the API and the data it returns. Please notify the OpenFEMA Team at if you notice data discrepancies, changes to feature behavior, or excessive download/access times.
