Cisco ASA Software Release and Support Timeline
PB738209
Released: November, 2016
Note: This product bulletin describes the new support timeline for Cisco ASA releases starting from Cisco ASA
9.5(1) and onwards. For the support timeline of previous ASA releases, please refer to this page
Introduction
This product bulletin describes the release and support timeline and end-of-life (EoL) guidelines for Cisco ASA
Software on the Cisco
®
ASA 55XX-X Series Security Appliances.
Cisco ASA Software is a time-based release as opposed to a feature-based release. This approach provides for
frequent delivery of individual releases, enabling Cisco to introduce a greater number of stable ASA Software
releases with fewer new features in each release. As a result, the customer release qualification time of each
release may be reduced.
Consequently, these end-of-sale and EoL guidelines of the Cisco ASA Software may differ from the guidelines of
other traditional Cisco Software releases. This product bulletin describes these milestones and any difference to
the standard end-of-sale and EoL milestones.
Cisco ASA Software Release Delivery
Cisco is introducing a new software release delivery model and specific EoL guidelines with the ASA Software
release 9.5(1).
The Cisco ASA Software Release Train model provides two distinct release vehicles combining to deliver new
features 3 times a year with regular rebuilds for fixes. The schedule specifies three individual software releases at
4-month intervals within a 12-month cycle. This cadence is repeated every year.
The Spring Release, which usually ships in March is an Extended Maintenance Release and it is designated by an
even number in the second digit of the series x.ev
en(n), where x = major series, “even” represents a yearly
increment for that series and “n” is the number of rebuilds in that particular release. This is represented in Figure 1.
The Summer Release, which usually ships in July is a Standard Maintenance Release and thus is designated an
odd number in the second digit of the series x.odd(n). This Release also introduces new features in its first rebuild
in the fall to provide increased feature velocity to meet the customer and market demands. The fall rebuild usually
ships in November.
