## Available versions

You can see the available versions (e.g. to check what is the current latest) in the [Release Notes](../release-notes.md){.internal-link target=_blank}.

## About versions

Following the Semantic Versioning conventions, any version below `1.0.0` could potentially add breaking changes.

// BuildInfo describes version information about the binary build.

	Version       string `json:"version"`
	GitRevision   string `json:"revision"`

// Compare returns -1, 0, or +1 depending on whether
// x < y, x == y, or x > y, interpreted as Go versions.
// The versions x and y must begin with a "go" prefix: "go1.21" not "1.21".
// Invalid versions, including the empty string, compare less than
// valid versions and equal to each other.
// The language version "go1.21" compares less than the
// release candidate and eventual releases "go1.21rc1" and "go1.21.0".
