NGINX Instance Manager 2.4.0 release notes
## Upgrade Paths {#2-4-0-upgrade-paths}

NGINX Instance Manager 2.4.0 supports upgrades from these previous versions:

- 2.1.0 - 2.3.1

If your NGINX Instance Manager version is older, you may need to upgrade to an intermediate version before upgrading to the target version.

## What's new {#2-4-0-whats-new}

This release includes the following updates:

- [icon: feature] **Get notified about critical events**<a name="2-4-0-whats-new-Get-notified-about-critical-events-34262"></a>

   Instance Manager 2.4 adds a notifications panel to the web interface. After logging in to NGINX Management Suite, select the notification bell at the top of the page to view critical system events (`WARNING` or `ERROR` level events). Future releases will support additional notification options.

- [icon: feature] **See which of your NGINX Plus instances have NGINX App Protect installed**<a name="2-4-0-whats-new-See-which-of-your-NGINX-Plus-instances-have-NGINX-App-Protect-installed-34879"></a>

   Now, when you [view your NGINX Plus inventory](/nim/licensing-and-reporting/report-usage-connected-deployment.md), you can see which instances have [NGINX App Protect](https://www.nginx.com/products/nginx-app-protect/) installed. NGINX App Protect is a modern app‑security solution that works seamlessly in DevOps environments as a robust WAF or app‑level DoS defense, helping you deliver secure apps from code to customer.
