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.
