# Trellix EDR Release Notes (Cloud) - October 2026

This Trellix Endpoint Detection and Response - Cloud October 2026 release includes new features, enhancements, and resolved issues.

Every update release is cumulative and includes all features and fixes from the previous release.

## **New or changed**

### **Historical Search API support for PID and PPID queries**

The Historical Search API now supports filtering search queries by process ID (`pid`) and parent process ID (`ppid`). For more information, see [API sample for historical search - POST request](https://docs.trellix.com/docs/post-request-4).

## **Resolved issues**

| Reference | Resolution |
| --- | --- |
| SEC-213719 | Resolves an issue where the Threat Behavior and Process Activity sections on the **Monitoring** dashboard took longer than expected to load upon threat selection. The search query optimization restores the expected page load speeds. |
| SEC-213804 | Resolves an issue where post-authentication redirection to the EDR console caused page load delays. |
| SEC-215956 | Resolves an issue where GET status and GET result Historical Search API calls failed with a `400 Bad Request` error for exported search results. The updated request payload format now ensures successful responses. |
