🌟 What's new

🎉 New features

🖌 Bitmask support for precise image annotation

There is a new BitmaskLabels tag to support pixel-level image annotation using a brush and eraser. This new tag allows for highly detailed segmentation using brush-based region and a cursor that reflects brush size down to single pixels for fine detail. We’ve also improved performance so it can handle more regions with ease. (#7766 #7799 #7852)

Additionally, Mac users can now use two fingers to pinch zoom and pan images for all annotation tasks.

🔤 Custom global hotkeys

You can now configure global hotkeys for each user account. These are available from the Account & Settings page. (#7784)

✅ Feature updates

▶️ One-click annotation for audio-text dialogues

When labeling paragraphs in dialogue format (layout="dialogue"), you can now apply labels at an utterance level. (#8037)

There is a new button that you can click to apply the selected label to the entire utterance. You can also use the pre-configured Command + Shift + A hotkey:

⚙️ Settings for TimelineLabels configurations

When you are using a labeling configuration that includes <TimelineLabels>, you will now see a settings icon. (#8011)

From here you can specify the following:

  • Playback speed for the video
  • Whether to loop timeline regions
2-28-settings

↕️ Adjustable height for audio players

While you can still adjust the default height in the labeling configuration, now users can drag and drop to adjust the height as needed. (#8116 #8138)

2_29_adjust.mp4

✏️ Apply labels from multiple <Labels> controls

When you have a labeling configuration that includes multiple <Labels> blocks, like the following:

<View>
<Text name="text" value="$text" granularity="word"/>
<Labels name="category" toName="text" choice="single">
  <Label value="Animal" background="red"/>
  <Label value="Plant" background="darkorange"/>
</Labels>
<Labels name="type" toName="text" choice="single">
  <Label value="Mammal" background="green"/>
  <Label value="Reptile" background="gray"/>
  <Label value="Bird" background="blue"/>
</Labels>
</View>

You can now choose multiple labels to apply to the selected region. (#8162)

2-29-multilabels.mp4

⏱ Support for high-frequency rate time series data

You can now annotate time series data on the sub-second decimal level. (#8056)

Note: Your time format must include .%f to support decimals.

For example:
timeFormat="%Y-%m-%d %H:%M:%S.%f"

Special thanks to @dronishe for reporting this issue (7948)

🧩 Improved UI for empty Data Manager

When loading the Data Manager in which you have not yet imported data, you will now see a more helpful interface. (#8149)

image

🔳 Snap bounding boxes to pixels

The <Rectangle> and <RectangleLabels> tags now include the snap parameter, allowing you to snap bounding boxes to pixels. (#8045)

Tip: To see a pixel grid when zoomed in on an image, you must disable pixel smoothing. This can be done as a parameter on the <Image> tag or from the user settings.

📌 Define the default collapsed state

The <Collapse> tag now includes an open parameter. You can use this to specify whether a content area should be open or collapsed by default. (#7993)

🌈 Configure whether to display spectrograms in the labeling configuration

There is a new spectrogram parameter for the <Audio> tag, allowing you to show spectrograms by default. (#7762 #7788)

⭐️ SDK 2.0.x

We released a new version of the SDK, with multiple functional and documentation enhancements.

🌟 What's new

🎉 New features

⏱ Time series synchronization with audio and video

You can now use the sync parameter to align audio and video streams with time-series sensor data by mapping each frame to its corresponding timestamp. (#7376)

Very special thanks to @cloudmark for contributing this feature!

video-time-series-light.mp4

For more information, see Time Series Labeling with Audio and Video Synchronization.

🌈 Spectrogram support for audio analysis

There is a new option to display audio files as spectrograms. You can further specify additional spectrogram settings such as windowing function, color scheme, dBs, mel bands, and more.

Spectrograms can provide a deeper level of audio analysis by visualizing frequency and amplitude over time, which is crucial for identifying subtle sounds (like voices or instruments) that might be missed with traditional waveform views. (#7400)

Thank you again to @cloudmark for contributing this feature as well!!

✨ Group multiple time series in one channel

There is a new Multichannel tag for visualizing time series data. You can use this tag to combine and view multiple time series channels simultaneously on a single channel, with synchronized interactions.

The Multichannel tag significantly improves the usability and correlation of time series data, making it easier for users to analyze and pinpoint relationships across different signals. (#7669)

⚙️ Support for JSONL

Label Studio now supports more flexible JSON data import from cloud storage. When importing data, you can use JSONL format (where each line is a JSON object).

JSONL is the format needed for OpenAI fine-tuning, and the default format from Sagemaker and HuggingFace outputs. (#7555)

📐 Improved grid view configurability

You can now configure the following aspects of the Grid View in the Data Manager: (#7640)

  • Columns
  • Fit images to width

🌟 What's new

🎉 New features

🔗☁️ Storage proxies for cloud files

Label Studio now uses a proxy when accessing media files in connect cloud storages. For more information, see Pre-signed URLs vs. storage proxies. (#7354)

Proxy mode is only used when the Use pre-signed URLs option is disabled in source storage.

Storage proxies offer simplified configuration and improved performance.

  • Keeps data access within Label Studio's network boundary, ideal for on-premise environments
  • Enforces strict task-level access control, even for cached files
  • Eliminates the need for presigned URLs and CORS configuration
  • Solves performance and reliability issues for large files, videos, and audio
  • Media is now streamed via proxy, improving compatibility and scalability

📑 Multi-task JSON imports for cloud

Previously, if you loaded JSON tasks from source storage, you could only configure one task per JSON file. (#7540)

This restriction has been removed, and you can now specify multiple tasks per JSON file as long as all tasks follow the same format.

For more information, see the examples in our docs here.

⚡️ Sample datasets

When creating a new project, you can now select sample datasets for images and text. This will make it easier to create new projects for proof-of-concept and testing work. (#7206)

image

📖 New PDF tag

A new PDF tag lets you directly ingest PDF URLs for classification without needing to use hypertext tags. (#7460)

✅ Feature updates

🖌 Dynamic brush sizes

The cursor now adjusts dynamically to brush size to allow for more precision in segmentation tasks. (#7484)

Special thanks to community members @Zensome for reporting this in issue #6684, @thesby for reporting this in issue #6337, @stobias123 for reporting this in #3774, and @newzealandpaul for reporting this in issue #2792!

brush-size.mp4

📍 KeyPointLabel exports for COCO and YOLO

COCO and YOLO export formats now available for KeyPointLabels. (#7467)

Special thanks to community member @tlpss for requesting this in issue #2851!

For more information, see the documentation.

🔒 Security

  • Removed an unused endpoint. (#7440)

  • By default, CORS is permissive. However, you can now set an environment variable to ensure it is in strict mode. Set one of the following (#7448) :

    • CORS_ALLOWED_ORIGINS
      A comma-separated list of Origin header values the Label Studio server will receive, e.g. https://example.org,https://example.net

    • CORS_ALLOWED_ORIGIN_REGEXES
      Same as above, except using regex.

    • CORS_ALLOW_ALL_ORIGINS
      Set to false or 0 to reject all Origin header values (that is, allow no cross-origin requests). By default this is set to true.

🐞 Bug fixes

  • Fixed an issue where the Filter tag did not work with Choices tags. (#7481)

    Special thanks to user Tanveer Anzoom @ctanveer for reporting this bug on Slack!

  • Fixed several issues associated with dark mode (in beta). (#7513, #7514, #7485, #7492, #7472, #7490, #7576)

  • Fixed an issue where forward and rewind hotkeys for audio were not working. (#7426)

  • Fixed an issue where the annotator’s avatars were improperly faded in the Data Manager. (#7503)

  • Fixed an issue with cloud storage in which tasks would not resolve correctly if they referenced data in different buckets. (#7458)

  • Fixed an issue where certain drop-down menus were inaccessible at different zoom levels. (#7479)

  • Fixed an issue where there were some UI inconsistencies that would occur during certain page navigations. (#7420)

  • Fixed an issue where the Data Manager would go blank when filtering by the predicted model version. (#7477)

  • Fixed an issue where when moving around panels in the labeling interface, groups were not sticking in place. (#7512)

  • Fixed an issue where, if a 500 error was returned when syncing storage, the user would not see the error. (#7442)

  • Fixed an issue where the token refresh function was not using the user-supplied httpx_client. (#7572)

  • Persistent storages now function without nginx. Non-standard files like PDF, CSV, and others are downloaded correctly. (#7572)
