5.X Software Release Examples - Cisco IPS-4240-K9 - Intrusion Protection Sys 4240 Installation Manual

IPS Software Versioning
Service packs are cumulative following a base version release (minor or major). Service packs are used
for the release of defect fixes with no new enhancements. Service packs contain all service pack fixes
since the last base version (minor or major) and the new defect fixes being released. Service packs
require the minor version.
Signature updates are cumulative and increment by one with each new release (for example, S145, S146,
S147). Signature updates include every signature since the initial signature release (S1) in addition to
the new signatures being released. Signature updates require the minimum version listed in the filename.
To install the most recent signature update, you must have the most recent minor version. Service packs
are dependent on the most recent minor version, which is dependent on the most recent major version.
