New Features
New Features in ASA 8.4(2.8)
Released: August 31, 2011
lists the new features for ASA interim Version 8.4(2.8)/ASDM Version 6.4(5.106).
Note
We recommend that you upgrade to a Cisco.com-posted ASA interim release only if you have a specific
problem that it resolves. If you decide to run an interim release in a production environment, keep in
mind that only targeted testing is performed on interim releases. Interim releases are fully supported by
Cisco TAC and will usually remain on the download site only until the next maintenance release is
available. If you choose to run an interim release, we strongly encourage you to upgrade to a fully-tested
maintenance or feature release when it becomes available.

The ASA now supports clientless SSL VPN with Microsoft Internet Explorer 9 and Firefox 4.
Also available in Version 8.2(5.13) and 8.4.2(8).
Compression for DTLS and

To improve throughput, Cisco now supports compression for DTLS and TLS on AnyConnect

configuration is to have both SSL and DTLS compression as LZS. This feature enhances
migration from legacy VPN clients.

Note
Using data compression on high speed remote access connections passing highly
compressible data requires significant processing power on the ASA. With other
activity and traffic on the ASA, the number of sessions that can be supported on the
platform is reduced.
