Highlights​

MCP Server​

The new Memfault MCP (Model Context Protocol) server lets MCP-compatible AI assistants like Claude Desktop, Claude Code, Cursor, VS Code, and others connect directly to your projects and query fleet data on your behalf. Authenticate once via OAuth, and empower your assistant's reasoning with read-only access to Issues, Traces, Device info, Metrics, and Software Version stats. See the MCP Server documentation to get started.

Cellular and Wi-Fi Location Services Now Available ​

You can now track your devices via single-cell, multi-cell or Wi-Fi location services with Memfault. Setup is simple and can be completed in a few steps, giving you access to your choice of location technologies and competitive pricing.

To learn more check out the Location Services docs to get in touch with the team.

Reports: Expand All​

The Reports view now has an Expand All / Collapse All button at the top of the list, making it easy to review all entries at once instead of clicking into each row individually.

The video above demonstrates the Expand All / Collapse All button toggling all report rows open and closed at once.

Highlights​

Fleet-wide CDR Viewer​

A new Custom Data Recording (CDR) viewer lets you browse CDR payloads across your entire fleet, instead of only from a single device's timeline. Browse recordings by type, filter by Cohort, and jump straight into the payloads that matter without clicking into each device one at a time.

Stack Usage Visualization in Trace Viewer​

Trace Viewer now includes a stack usage visualization for traces that contain stack data, making it easy to spot threads approaching their limits at a glance instead of mousing over each one. The thread list also shows a thread count, and the Process selector is hidden when a trace has only one unnamed process (typical for bare-metal MCU traces).

Highlights​

Export Device Vitals​

Device Vitals columns are now included in device CSV exports.

You can also export data directly from a single device's detail page, making it easier to pull a single device's history for offline analysis or sharing with hardware teams.

Trace Count Grouped by Software Version​

Issue Chart: Trace Count Over Time cards now support a "Software Version" group-by option, letting you see trace volume broken down by the versions of software running across your fleet. This makes it easy to confirm whether a bug affects a specific release or spans multiple versions.

Highlights​

Linked Devices Always Visible on Device Detail​

A new Linked Devices bar on the Device Detail page makes related devices permanently visible without expanding the header. For products where a gateway, companion app, or companion hardware are paired to the primary device, this surfaces those relationships right where you need them during debugging.

Log Explorer Copy Improvements​

Copying from the Log Explorer now produces clean, tab-separated output (timestamp, level, message) ready to paste into a spreadsheet or bug report. Multi-row selection with keyboard shortcuts is also supported, making it faster to grab exactly the lines you need.

General​

• New self-serve customers signing up on app.nrfcloud.com are now automatically redirected into the Memfault experience after signup, streamlining onboarding for nRF Cloud customers.
• When using Bulk Device Upload, CSV device upload error messages are now clearer when specified hardware versions don't yet exist.

Highlights​

Issue Trends at a Glance​

The Issue List page now shows trace volume trend charts for each issue, covering the last 14 days, 8 weeks, or 12 months. You can now spot growing problems, stable regressions, and recovering issues without opening each one individually.

Improved Software Version Filtering in Device Search​

The software version filter in Device Search has been overhauled. It now lives in a dedicated filter panel with support for AND conditions, regex, semver comparison operators, and "any of" / "not any of" matching - making it much easier to precisely target device populations across complex version landscapes.

Highlights​

Reboot Gaps in the Device Timeline​

The device Timeline now inserts visual gaps in swimlanes at reboot boundaries, preventing misleading data interpolation across reboots. This makes it immediately clear when a metric or session span crossed a device restart, giving you a more accurate picture of device behavior over time.

Release Notes Now Support Markdown​

The Notes field on Releases now uses a rich Markdown editor and viewer. Teams can format release notes with headers, lists, code blocks, and links - making it easier to communicate what changed in each build to everyone on the team.

General​

• Improvements to the Cohort version UI to improve performance and reliability when the project contains large numbers of versions.

Highlights​

Saved Issue Search Digest Emails​

Building on the saved issue search feature shipped in August, you can now subscribe to daily or weekly email digests for any saved search. Each digest highlights new and regressed issues in your search results, ranked by fleet impact - so your team stays informed without having to check the dashboard manually.

🧪 Custom Device Overview with Embedded Dashboards​

The Device Details Overview has experimental support for embedding a dashboard with the slug device-details, automatically scoped to the individual device. This unlocks fully custom per-device views - making the device detail page as informative and tailored as your fleet-level dashboards. Please

contact us if you'd like early access.

Improved Linux Support​

We've introduced Python crash support and custom trace capture for Linux devices. These updates close observability gaps where Python apps mix native code or where failures don't trigger kernel crashes. With full Python stack traces and structured custom traces integrated directly into Memfault Issues, you can now capture a broader range of problems, see them grouped fleet-wide, and get the same alerts and contextual data you rely on for other issues.

Saved Issue Search and Summaries​

Managing issues across large and fragmented fleets just got much easier. You can now save filtered issue searches, pin your favorites to the sidebar for fast access, and even subscribe to scheduled email summaries that notify you of changes in the issues that matter most. This ensures your team gets higher-signal alerts without the noise.
