Release 4.3

November 8, 2026

BlazeMeter 4.3 lets you inspect full request and response data for any request in AI Auto Correlation, rather than only failed requests. Taurus Cloud 2.4.562-reduced resolves 29 vulnerabilities in Pillow (including five critical) and three additional critical or high vulnerabilities; no customer action is needed for the Pillow update.

Request details in AI Auto Correlation | Performance testing

The Request detail button (magnifying glass icon) in the AI Auto Correlation middle panel is now available for all requests, not only failed ones. It opens the full request and response from the dry run, so you can review the actual data instead of just the status code. Export cURL is now a compact icon with a tooltip, and long URLs are scrollable.
