# Chainstack Self-Hosted v2.2.0: June 4, 2026

> Node configuration management with tracked revisions, zero-downtime disk growth, a rebuilt workflow-based orchestration engine, and built-in monitoring metrics.

This release brings node configuration management into the Control Panel, makes disk growth a zero-downtime operation, and rebuilds the orchestration engine for more reliable, observable deployments.

## Node configuration and revisions

Every node now has a configuration tab where you can review its current settings, change client and resource options, and apply those changes as a tracked revision.

* **Configuration tab** — review a node's current settings and change client and resource options in one place.
* **Tracked revisions** — each apply is recorded with its author and a diff of what changed, giving you a full history of how a node's configuration evolved over time.
* **Live status** — revision status updates as a change rolls out, so you can watch progress instead of guessing.
* **Up-front validation** — the Control Panel surfaces clear errors before a change is applied, for example when you attempt to shrink storage below its current size.

## More reliable deployment operations

The engine that drives deployments, upgrades, and deletions has been rebuilt to run each operation as a first-class workflow.

* **Automatic retries** — failed steps retry automatically rather than leaving an operation stuck.
* **Clean cancellation** — in-flight operations can be cancelled cleanly.
* **Progress reporting** — long-running actions report progress instead of going dark.

The result is fewer stuck deployments and clearer visibility into what the platform is doing on your behalf.

## Built-in monitoring metrics

The Control Panel now exposes its own metrics and ships scrapers for the components that matter to operators — PostgreSQL, the Control Panel services, Temporal, and the blockchain nodes themselves. This makes it easier to wire the platform into your existing observability stack without assembling per-component exporters by hand.

## Refreshed deployment experience

The node list, node details tabs, and resource selectors have been rebuilt on the latest design system for a cleaner, more consistent interface.

* **Full preset coverage** — the deployment flow now shows every available preset configuration for a network rather than just the first match.
* **Kubernetes-standard units** — capacity is expressed in Kubernetes-standard units (Gi/Ti) throughout.
