🖼️ Image Panel: Overlay Image Topics​

The Image panel now supports overlay image topics, letting you layer segmentation masks, depth maps, or other image data directly on top of the base camera feed.

🔷 Draco-Compressed Point Clouds​

The 3D panel now renders Draco-compressed foxglove.CompressedPointCloud topics, so you can visualize large point clouds with smaller on-wire payloads. Read more about CompressedPointCloud.

📈 Plot Panel: Seek and Preview From the Chart​

When the Plot panel X-axis type is Message path, hovering a point updates preview time for the player and panels, and clicking a point seeks playback to that time.

📎 MCAP Metadata & Attachments​

The left sidebar adds Metadata and Attachments tabs for MCAP files and cloud recordings, so you can inspect key–value metadata and file attachments without leaving the view.

📅 Interactive Timeline​

The Timeline now shows device coverage on a continuous time axis—one row per device—so you can pan and zoom within the range you care about. Hover along a row to see device and time, drag to select a range that stays visible until you dismiss it, and share links that open with your selection already in view.

📈 Plot Panel: Current and Preview Point Indicators​

When the Plot panel X-axis value type is set to Message path, a visual indicator now highlights the points at the current playback time. Hovering over the playback timeline shows a preview indicator at the corresponding data points.

🖼️ GPU-Accelerated Image Decoding​

Raw image decoding in the Image and 3D panels now uses WebGPU for faster performance when available, falling back to software decoding when it isn't. This release also adds NV12 (YUV 4:2:0) support and more accurate colors for common UYVY and YUYV camera formats.

New & Improved

• Gauge, Indicator, Markdown, and State Transitions panels now reject Plot-only time-series message path functions with clear errors; Plot continues to support them

🤖 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.

🔍 AI-Powered Docs Search​

The documentation site now features AI-powered search. Ask a question in natural language and get a synthesized answer drawn from the docs, alongside traditional keyword results.

🔧 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:

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
