1.21.0

Helm Chart version: [1.11.3](https://github.com/HumanSignal/charts/blob/master/heartex/label-studio/Chart.yaml)

# 🌟 What's new

## 🎉 New features

### 🖌 Bitmask support for precise image annotation

There is a new [BitmaskLabels](https://labelstud.io/tags/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](https://labelstud.io/guide/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>`](https://labelstud.io/tags/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

### ↕️ 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)

https://github.com/user-attachments/assets/7b720213-9e35-47f1-a249-95d50709adf7

### ✏️ 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](https://labelstud.io/tags/timeseries) 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](https://github.com/HumanSignal/label-studio/issues/7948))

### ☁️ 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.

<img width="832" height="816" alt="image" src="https://github.com/user-attachments/assets/0ca48ff4-9c06-4f40-9232-254e8d4dfdef" />

### 🧩 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)

<img width="1355" height="779" alt="image" src="https://github.com/user-attachments/assets/c5a6062e-0f6e-4aae-bda9-2abcd5a90f56" />

### 🔳 Snap bounding boxes to pixels

The [`<Rectangle>`](https://labelstud.io/tags/rectangle) and [`<RectangleLabels>`](https://labelstud.io/tags/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>`](https://labelstud.io/tags/image) tag or from the user settings.


### 📌 Define the default collapsed state

The [`<Collapse>`](https://labelstud.io/tags/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.

[Documentation](https://api.labelstud.io/)
