Summarize the major recent changes that affected installer-managed deployments, runtime promotion, updates, and realtime behavior.

Recent Platform Changes

Recent platform work hardened several sensitive areas:

installer-first setup and guided runtime promotion
domain-aware TLS and cert issuance validation
control-plane self-update with prepared/apply semantics
split Updates Center for control plane versus agent updates
full-screen freeze modal during control-plane apply
corrected runtime health and route probing
HA-safe realtime fanout for node install progress and live metrics

These changes are already reflected throughout the docs tree. This page exists to provide a high-level release narrative for the current control-plane line.

Focus on node install progress, live metrics freshness, and the new Updates Center separation between control-plane state and agent rollout state.

Focus on installer-managed self-update, releaseId, runtime promotion, route probes, and host-side supervisor orchestration.

Focus on the cross-repo contract changes: OpenAPI export, docs sync, release manifests, runtime health semantics, and HA-safe realtime fanout.
