October 2024 Release Notes

RUM error monitoring, LCP optimization, better lab data exports, and more.

Here's what's new in DebugBear for October 2024.

RUM error monitoring

DebugBear now supports error monitoring for real user monitoring (RUM) customers. We're not just tracking performance metrics, but also JavaScript errors that occur on your website.

Error monitoring is disabled by default, but you can enable it as shown in the documentation.

Error message grouping makes it easy to identify the most common errors on your website:

LCP Optimize Tab

We've added a new tab to the LCP section of Real User Monitoring. You can try it out here on our public demo website.

The Optimize tab guides you through the process of finding and fixing issues that affect your LCP score. The steps offered are:

1. Select a page: Choose a page to drill down into.
2. Check what's causing poor LCP: Identify the significant LCP sub-parts that are affecting your score.
3. Check what content is counted as the LCP element: Understand what content is being counted as the LCP element.
4. Review specific visitor experiences: Inspect individual visitor experiences to understand their journey, device, and network conditions.

tip

An Optimize tab is also available for the First Contentful Paint (FCP), Time to First Byte (TTFB), and Interaction to Next Paint (INP) metrics.

Chrome and Lighthouse upgrades

Chrome has been upgraded from version 127 to 130, and Lighthouse has been upgraded from version 12.2.0 to 12.2.1 bringing performance improvements and bug fixes. DebugBear users do not need to take any action to benefit from these upgrades.

Better lab data exports

When you export project lab data from the DebugBear dashboard, the date range is now taken from the date selector instead of hard-coded to last 8 weeks. Longer time ranges are also supported now.
