🤖 URDF Joint State Control​

URDF robot models in the 3D panel can now be driven directly by sensor_msgs/JointState or foxglove.JointStates messages, performing forward kinematics within Foxglove. Previously, URDF visualization required publishing tf transforms, which often meant running complex forward kinematics calculations outside the app. See an interactive version in this playground.

🗂️ Sessions​

Sessions let you group recordings from a single device into logical units — a drive, a mission, a field test — so you can organize and visualize data by context rather than by file boundaries. Define custom properties (location, stack version, mission type) to filter and search across sessions, and open a session to load all its recordings as one continuous dataset. See docs, currently available on Team and Enterprise.

🔌 Remote Data Loaders​

Remote Data Loaders connect Foxglove to any queryable data source — internal databases, custom storage systems, or proprietary data lakes — by building a lightweight backend that produces MCAP on demand. The Remote Data Loader handles caching, seeking, and streaming so your team can visualize data directly from where it already lives, without exporting or re-uploading.

⌨️ Embedded Viewer Keybinding API​

The embedded viewer now supports keyboard shortcut customization. Teams embedding Foxglove into review tools or operator dashboards can override or suppress built-in shortcuts that conflict with the host application, and register custom keybindings that notify the parent — enabling keyboard-driven workflows like assigning quality ratings, navigating recording playlists, or controlling playback without leaving the embedded viewer.

🔧 Message Path Functions​

Message path syntax has been expanded with several new functions and capabilities. Use .@radians and .@degrees for unit conversion, .@timedelta to calculate time differences between consecutive messages, and .@rpy to convert quaternions to roll/pitch/yaw. Functions can now be chained together (e.g., /[email protected].@degrees), and filter expressions support enum names (e.g., /topic{status==OK}) with autocomplete suggestions. "Math modifiers" have been renamed to "message path functions" to reflect the broader scope.

🗺️ Depth Map Point Cloud Improvements​

Depth image point clouds in the 3D panel now support colorization using a sibling RGB topic, making it easy to visualize color-mapped depth data from RGB-D cameras like Intel RealSense and Luxonis. This release also adds support for grayscale PNG depth images and custom color modes for 32FC1 and 8UC1 depth images in the Image panel.

📁 Global File Drag and Drop​

Drop supported files anywhere on the view or dashboard pages to open them. Drag .mcap and other data files onto the app to load them in the current session, or drop .foxe extension files to install them—no need to navigate to a specific panel first.

🏷️ Map & Image Panel Tooltip Updates​

The Image panel now supports hover tooltips for annotations. Also, both the Image and Map panel's tooltips can now display custom metadata. LocationFix and ImageAnnotations messages support a new optional metadata field (added in foxglove schemas v1.10.1), and GeoJSON features can include properties.metadata. Use metadata to surface information like object IDs, classification labels, or sensor info directly in your visualizations.

🗂️ Desktop Tabs​

The Foxglove desktop app now supports tabbed browsing, letting you work with multiple data sources, layouts, and views within a single window.

• Create new tabs to work with different data files, layouts, or projects side-by-side without juggling multiple windows
• Drag and drop tabs to reorder them within the tab bar
• Each tab maintains its own navigation history—use the back and forward buttons to navigate within a tab

Keyboard shortcuts:

Action	Shortcut
New Tab	Cmd/Ctrl + T
Close Tab	Cmd/Ctrl + W
Next Tab	Ctrl + Tab
Previous Tab	Ctrl + Shift + Tab
Last Active Tab	Cmd/Ctrl + /
Back	Cmd/Ctrl + [
Forward	Cmd/Ctrl + ]

📍 Image Panel Cursor Publishing​

The Image panel now includes publish settings that let you emit real-time cursor position events. Configure topics in the panel settings:

• Hover topic: Publishes cursor position continuously as you move the mouse over the image
• Click topic: Publishes cursor position when you click on the image

Messages are published as foxglove.Point3InFrame (non-ROS) or geometry_msgs/PointStamped (ROS), making it easy for downstream systems to react to cursor interactions.

🗺️ Map Panel Updates​

The Map panel has several improvements:

• GPS coordinates now display in the HUD, and tooltips show topic information when hovering over points and GeoJSON features
• A new "Last N seconds" sliding time window history mode lets you display only recent data, improving performance with large datasets
• Color swatches now appear in topic section headers, making it easier to identify topics when collapsed
• "Expand all" and "Collapse all" options for topic lists make it easier to navigate complex configurations
• A visibility filter lets you quickly find visible or hidden topics

New & Improved

• Added "Expand all" and "Collapse all" options to topic and series lists in the 3D, Image, Plot, State Transitions, and Log panels
• Added a 10x playback speed option to the playback controls dropdown menu

📋 Copy & Paste Tabs Across Layouts​

You can now copy and paste entire tabs—including all their panels and configurations—across layouts using the system clipboard. Right-click any tab to access "Copy tab" or right-click the tab bar background for "Paste tab." This makes it easy to reuse complex tab setups across different layouts.

🗺️ OpenSeaMap Layers for Map Panel​

The Map panel now supports additional overlay layers for nautical charts. Add Sea Marks, Shaded Relief (bathymetry), or Isobaths (depth contours) on top of your base map layer. Each layer can be toggled, reordered, and have its opacity adjusted independently.

📊 Bar Style for Gauge Panel​

The Gauge panel now supports a "bar" style in addition to the existing dial style. Choose the visualization that best fits your data—use the dial for traditional gauge readouts or the bar for linear progress indicators.

🎯 Drag & Drop from Settings Sidebar​

Topics and message paths can now be dragged from a panel's settings sidebar onto other panels. This makes it easy to quickly inspect topics in Raw Messages, add series to a Plot, or duplicate series from one panel to another.

New & Improved

• Connection dialogs now show the 3 most recent connections for that specific source type, making it easy to quickly reconnect
• The Topics sidebar now shows the encoding used for each topic

• Message Path autocomplete now suggests nested fields when typing inside a filter
• Improved Message Path Input brace behavior—closing braces are only auto-inserted when typing at the end, and deleting an open brace removes the matching closing brace
• Added support for 2D Pose click-to-publish for non-ROS servers
• Compressed video can now be synchronized with annotations
• Downloaded MCAP files from the Timeline view now include both device name and timestamp in the default filename
• Added query syntax validation to the metadata search field with user-friendly error messages

• Breaking: ULog files now use the foxglove.Log schema for log messages instead of rosgraph_msgs/Log. The synthetic log topic is renamed from Log to _log. User Scripts or layouts referencing Log.msg, Log.header.stamp, or ROS log level values from ULog files will need to be updated.

Fixes

• Fixed nearest neighbor interpolation for non-square grids in the 3D panel
• Fixed Fisheye62 camera projection for wide-angle lenses with FOV greater than 180° in the 3D panel
