Major, Minor, and Maintenance Releases
This section describes the differences between major, minor, and maintenance releases. Each Cisco BLISS for Cable major release can include a series of minor (2.n) and/or maintenance releases (2.n.n) following the major release. Release notes are issued only if new information is available.
•Major Release—Major software releases contain significant new features, enhancements, changes, and/or defect fixes. The major release number increments with each new version (1.0, 2.0, 3.0, and so on), and numbers cannot be skipped. Subsequent major releases are based on previous major releases and contain defect fixes from each previous release throughout the life cycle of the release.
•Minor Release—Minor (or "point") software releases usually have a few new features of limited scope, enhancements, and/or defect fixes. The minor release number increments as content is added, and minor release numbers can be nonsequential (2.1, 2.2, 2.4, and so on). Subsequent minor releases are based on previous major or minor releases and contain defect fixes from each previous major or minor release throughout the life cycle of the release.
•Maintenance Release—Maintenance software releases have no new features or enhancements. Maintenance releases include only defect fixes to address specific problems. Maintenance release numbers increment as content is added, and numbers can be nonsequential (2.2.1, 2.2.3, and so on). Subsequent maintenance releases are based on previous major, minor, or maintenance releases and contain defect fixes from previous releases throughout the life cycle of the release.

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
