2026-06-Miranda-release-notes

Welcome to the Miranda release! This release is named after Miranda, one of Uranus's most intriguing moons. Despite its small size, Miranda is home to Verona Rupes, the tallest known cliff in the solar system. While this release may be easier to navigate than Miranda's dramatic landscape, we hope you find its new features just as exciting to explore.

No-Code Transaction Test

No-Code Transaction tests allow you to capture and monitor critical user journeys without writing and maintaining test scripts. We know that building browser transaction tests has traditionally been a technical hurdle, so we've introduced a new browser-based recorder extension that automatically captures user flows as transaction instructions. This helps ensure your most critical workflows are operational from day one, whether you're a non-technical user or an engineer looking to save time.

We've also included a built-in WYSIWYG editor for easy maintenance and the ability to export to Playwright scripts. This provides a balance between simplicity and flexibility, making it easier for you and your team to focus on performance optimization and less on troubleshooting code.

Streaming Test

The new Playwright-based Streaming Test provides visibility into video playback performance for modern streaming formats, including HLS, DASH, and MP4. Running within a real Chromium browser environment, the test measures the playback experience from the moment a video source is assigned to the player through active playback and buffering events.

The Streaming Test captures key playback metrics that help teams understand startup performance and streaming quality, including:

• Initial Buffer: Startup delay before playback begins
• Play Time: Total time the video actively plays
• Total Buffer Time: Total time spent waiting for media data during playback
• Buffer Counter: Number of buffering events observed during playback

By measuring playback behavior directly within the browser, the Streaming Test provides insight into startup delays, buffering patterns, and overall viewing experience. These metrics help teams identify streaming performance issues, validate delivery quality, and monitor video playback performance. Streaming tests are available on Enterprise nodes.

Point Allocation

The Point Allocation UI has been redesigned to provide a faster, clearer, and more intuitive way to manage contract point allocations across divisions and products. The new interface introduces a modernized layout with enhanced visibility into allocation health, usage trends, and projected consumption, helping teams make more informed operational decisions with less effort.

Key improvements include:

• Allocation health indicators that quickly identify accounts that are at risk or have surplus capacity
• Projected usage metrics that help teams anticipate point consumption over the current billing cycle
• Simplified allocation management workflows with improved visibility into usage progress and enforcement settings
• Enhanced operational insight through centralized views of daily usage, total usage, and remaining contract capacity

These updates make it easier for teams to proactively manage allocations, reduce administrative overhead, and maintain better control over contract usage across their organization.

WebPageTest Instant Test Credential Script Variables

WebPageTest Instant Tests now support credential variables within WPT scripts, making it easier and more secure to test authenticated user workflows. Users can now configure saved username and password credentials directly within Instant Test authentication settings and automatically substitute those values into supported placeholders.

This enhancement simplifies script maintenance by removing the need to manually hardcode or repeatedly update credentials within test scripts. By securely reusing stored authentication values, teams can more easily validate login flows and authenticated experiences while improving operational efficiency and reducing exposure of sensitive information.

Endpoint Universal Binary

Catchpoint's Endpoint software for macOS has been upgraded from a Rosetta-dependent application to a native Universal Binary, providing native support for both Intel and Apple Silicon (M1, M2, M3, and newer) processors. This enhancement eliminates the need for Rosetta translation on Apple Silicon devices, resulting in improved performance, reduced resource consumption, faster startup times, and a more seamless user experience. By running natively on modern Mac hardware, the Endpoint software delivers greater efficiency, compatibility, and long-term support.

Endpoint Node ARM Support* (Preview)

Catchpoint's Enterprise Node now includes ARM support, giving teams more flexibility to run Catchpoint containers across modern infrastructure. With support for both traditional x86 and ARM-based environments, deployments can better align with cloud, edge, and developer platform choices. See Catchpoint's docker hub (catchpoint/enterprise-base - Docker Image ) for more details about which monitor types are supported for ARM.
