Software Lifecycle Overview
ZPE Systems software releases follow a structured life cycle designed to provide customers with a predictable and secure support experience. Each major software version progresses through three defined support phases over a five-year period:
Feature Support (Years 1 and 2): Full support including new features, hardware support, bug fixes, and security updates.
Maintenance Support (Years 3 and 4): No new features; continued bug fixes and security updates to ensure operational stability.
Security Support (Year 5): Only critical security patches and critical bug fixes; no feature updates or smaller bug fixes.
This phased approach ensures that customers benefit from innovation early in the cycle, followed by a focus on stability and long-term security. Customers with active support contracts have the option to choose between a stable version, currently in its Maintenance Support phase, and a fully support version, which is under active development on the Feature Support phase, and includes new features and enhancements. This provides customers with comprehensive coverage throughout the expected hardware lifecycle.
