🌟 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])

✏️ Apply labels from multiple <Labels> controls

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

:::xml
<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)

⏱ 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"

☁️ Improved cloud storage modal

When adding cloud storage, the modal has now been redesigned to add clarity and additional guidance to the process. (#8007 [#8057])

For example, you can now preview a list of files that will be imported in order to verify your settings.

🧩 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)

🔳 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.
