Resolved Issues in New Builds
Sometimes Cisco releases updated builds. In most cases, only the latest build for each platform is available on the Cisco Support & Download site. We strongly recommend you use the latest build. If you downloaded an earlier build, do not use it.
You cannot upgrade from one build to another for the same Firepower version. If a new build would fix your issue, determine if an upgrade or hotfix would work instead. If not, contact Cisco TAC. See the Cisco Firepower Hotfix Release Notes for quicklinks to publicly available Firepower hotfixes.
Use this table to determine if a new build is available for your platform.
