Future SEER*Stat Updates

  • The next expected significant feature/security enhancement will be incorporating Single Sign On (SSO) with Multi-Factor Authentication (MFA) into SEER*Stat. It will support Login.gov, NIH login, and IMS login service. We do not have a release date yet, but this will likely occur in Summer 2026. It will require an update of the client application.
  • In addition, there will be updates/patches for minor enhancements/bug fixes. Depending on the features/fixes, these may or may not require an update. In some cases, you would not be required to update, but you would have the option to download/install the new version.
  • This page will continue to be updated with information on new releases.
