Highlights​

Multi-Component OTA​

A single OTA Release can now carry artifacts for more than one updatable component, such as an application processor and a cellular modem, or a gateway and a downstream sensor MCU. The Add OTA Payload dialog has a new Component tab where you choose the component's software type and set a component version independent of the Release version. You can also upload per-component delta payloads. Read the Multi-Component OTA documentation to get started, and use the new memfault-cli flags (below) to upload component artifacts from CI.

The Payloads table on a Release now shows the software type and version of each component, with the primary software type marked explicitly. Associations between hardware versions and non-primary software types can be edited in Project Settings.

The OTA Releases table has a new Status column, on by default, showing whether each Release is Active, Not activated, or Aborted. The Create Release dialog now marks required fields and links to guidance on picking a version that matches what your devices report.

Highlights​

Saved Search Alerts​

Saved device and issue searches can now trigger alerts. Choose whether to be notified when a device or issue enters the search results, leaves them, or when the number of matches exceeds a threshold you set. Notifications go to the same email, Slack, and webhook targets used by your other alerts, and enter/leave alerts link straight to the devices or issues that triggered them. Manage every saved search alert - including editing and disabling them - from the new Saved search alerts view on the Alerts page.

Threshold alerts arrive as a summary of the matching devices or issues, with links to view them and to manage the alert.

Saved issue searches also get a new dropdown selector on the Issues page, like the one on the Devices page, with save, rename, delete, and favorite actions moved into the menu.

OTA Workflow and Release Health​

The OTA Releases pages have been updated to help you follow what a release does to your fleet after you activate it. The Releases table shows which cohorts each version is activated on, its device coverage, and when it was last activated and last installed. A new Release Health tab on each release compares device vitals such as expected battery life and sync success before and after the update, and shows how much of the target fleet is on the new version. You can pick which vitals tiles to show, and jump to a side-by-side software version comparison for the details. The Target Devices tab splits out devices that went offline before the rollout reached them, so they don't read as failed updates.

OTA Releases has a Columns button on the Releases table to show or hide optional columns, an "Add Note" banner on release details, and an Abort action next to Edit when activating by cohort. If a must pass through release has no artifact for a device's hardware version, the device is now shown as blocked rather than "On Target Version".

Highlights​

Saved Device Searches​

Device searches can now be saved, named, and reused across the app, the same way saved issue searches already work. Build a filter on the Devices page, save it, and it becomes available from the search dropdown, from a dedicated "All Saved Searches" page under the Devices section of the sidebar, and - for the searches you pin - directly in the sidebar itself. Saved searches show an asterisk when you have unsaved edits, and can be renamed or deleted from the kebab menu without rebuilding the filter from scratch.

The video above walks through saving a device search, managing it from the list page, and pinning it to the sidebar.

Redesigned Top Navigation​

The top navigation bar has been updated to match our design system, following last month's side navigation refresh. Icon sizing is now consistent across the bar, notifications have a clearer megaphone icon, and the timezone picker is now a button that displays the timezone you currently have selected instead of hiding it behind a menu. The redesign also brings a round of accessibility improvements to the header controls.

Highlights​

Redesigned Side Navigation​

The side navigation now uses expandable sub-menus for pinned dashboards and saved issue searches, instead of always listing every pinned item, and the footer was redesigned to be more compact - an icon with a tooltip for Admin (if you're an admin) and another for Support, instead of a full list of links.

Linux Custom Coredump Attributes​

You can now attach your own key-value attributes (feature flags, build metadata, hardware config, and similar) to Linux coredumps, and they show up directly on the trace's Attributes tab alongside the built-in fields. Useful for correlating a crash with device-specific state that isn't already captured elsewhere.

Highlights​

Issue Search: Stacktrace Column​

Issue search results now include a Stacktrace column, showing the frames matched by the "Stacktrace contains" filter directly in the results table instead of requiring a click into each issue. From the trace thread viewer, you can also hover over a stack frame and jump straight to issue search with that function name applied as a filter.

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.
