Maintenance mode, user attributes, and OpenTelemetry tracing
v0.6.0 · May 6, 2026
FerrisKey 0.6.0 introduces two major platform capabilities — a built-in maintenance mode and extensible user attributes — alongside full OpenTelemetry tracing support for production observability.
- Ships a first-class maintenance mode across the full stack, letting administrators halt user-facing operations gracefully during upgrades or incidents while retaining admin access.
- Adds user attributes support so realms can store arbitrary key-value metadata on users and propagate them into tokens via protocol mappers.
- Integrates OpenTelemetry tracing and OTLP log bridge for seamless compatibility with observability stacks such as Grafana Tempo and Jaeger.
Building on the passwordless and multi-tenant foundations of 0.5.0, this release shifts focus to operational control and extensibility — giving platform teams the tools to manage identity infrastructure with greater confidence.
