June 2024 Release Notes

· 3 min read

Better privacy with the RUM proxy, a new way of creating Page Groups, and improvements to the Engagement tab. Here's what's new in DebugBear for June 2024.

Better privacy with the RUM proxy

When you use DebugBear's Real User Monitoring (RUM) you can now choose to use a proxy server to collect data. This helps ensure that your users' IP addresses are not sent to DebugBear.

In addition, when you use your own server, it's likely that your server will not be blocked by ad blockers.

See our new documentation on the RUM proxy.

Create Page Groups with a regular expression pattern

DebugBear lets you group pages together to explore performance metrics for particular section of your website. You can now create Page Groups using a regular expression pattern for the full page URL - including query parameters in the URL.

Improvements to the Engagement tab

The Engagement tab now has two new charts:

Cumulative Layout Shift vs Click

This connects visual stability to user interactions. It shows whether layout shifts might be frustrating users by preventing them from clicking on page elements.
