Cisco ASA Interim Release Notes
The software images listed below are Interim releases. They contain bug fixes which address specific issues found since the last Feature or Maintenance release. The images are fully supported by Cisco TAC and will remain on the download site only until the next Maintenance release is available. If you do not have a specific problem which is resolved by an Interim release, we recommend that you use the Feature or Maintenance release images.
Important: These images were not fully regression tested. Each individual fix was unit tested, and the image has had a limited amount of automated regression testing to confirm a baseline of functionality. Keep this testing status in mind if you decide to run them in a production environment. We strongly encourage you to upgrade to a fully tested Maintenance or Feature release when it becomes available.
