# Chainstack Self-Hosted v2.7.1: July 17, 2026

> In-console update notifications, custom node sizing in the deployment wizard, server-side session revocation, and network and snapshot-restore reliability work.

This release focuses on keeping operators informed and in control: in-console update notifications, custom node sizing at deployment time, stronger session security, and a round of network-support and snapshot-restore reliability work.

## Update notifications and version awareness

The Control Panel now has a notification center. A bell icon in the header shows an unread badge, opens a slide-in drawer, and links to a dedicated notifications page grouped by date. When a newer version of a supported client or of the Control Panel itself becomes available, you get notified in-console instead of tracking releases elsewhere.

* **Notification center** — a header bell with an unread badge, a slide-in drawer, and a dedicated notifications page grouped by date.
* **Version awareness** — notifications when a newer client or Control Panel version becomes available.
* **Session-time fetch** — notifications are fetched when your session starts and can be dismissed individually or cleared all at once.

## Custom node configuration in the deployment wizard

The deployment wizard now includes a custom configuration option. Instead of accepting a preset as-is, you can tailor a node before you deploy it.

* **Per-client resources** — edit CPU, RAM, and storage per client, prefilled from the preset you started with.
* **Client-specific settings** — adjust client-specific settings alongside the resource values.
* **Detailed summary** — the summary step shows a per-component breakdown of everything you changed.
* **Preserved edits** — your changes are kept if you navigate back from the summary to make further adjustments.

## Stronger session security

Signing out now revokes the session's tokens server-side rather than only clearing them from the browser. Revoked tokens are tracked in a dedicated store and rejected on subsequent requests, closing the window where a previously issued token could still be used after logout.

## Broader and more reliable network support

* **TRON snapshot startup** — TRON nodes restored from a pruned RocksDB snapshot no longer crash-loop on startup.
* **TRON logs** — TRON logs now stream to standard output, so `kubectl logs` shows what the node is doing.
* **Polygon Heimdall retention** — Polygon Heimdall nodes ship with state pruning and block retention configured out of the box, keeping the blockstore bounded instead of growing unbounded after a snapshot restore.
* **Polygon preset** — a Polygon deployment preset is included.

## More reliable snapshot restores

* **Single-file compressed snapshots** — single-file compressed snapshots are now extracted correctly during download.
* **Filename preservation** — restored filenames are preserved end to end.
* **Automatic cleanup** — orphaned artifacts left behind by interrupted restores are cleaned up automatically.
* **Per-source placement** — snapshot data sources can target specific placement per source entry, giving you finer control over where restore data lands.
