HostVersion
HostVersion is a metadata identifier used in computing to denote the version of a host component, such as a server agent, virtualization host, or node participating in a distributed system. It is employed to communicate compatibility information between hosts and other entities, including clients, controllers, or orchestration systems. The exact definition and placement of HostVersion vary by project, but it is commonly included in handshake messages, configuration manifests, or monitoring payloads to aid in capability negotiation and debugging.
Format and scope: In most implementations HostVersion follows semantic versioning, represented as MAJOR.MINOR.PATCH, with optional pre-release
Purpose and usage: During initialization or reconfiguration, a client or controller reports its HostVersion to verify
Impact on governance: HostVersion helps maintain compatibility across components, supports diagnostics, and enables phased feature rollouts.
Security and reliability: Exposing version information can aid attackers, so systems may limit disclosure or sanitize
