# 🌟 What's New

## 🎉 New Features

### ⏮ ⏪ ⏩ ⏭ Paginated multi-image labeling 

Paginated multi-image labeling allows you to label an album of images within a single task. When enabled, a page navigation tool is available within the labeling interface. ([#6636](https://github.com/HumanSignal/label-studio/pull/6636), [#6724](https://github.com/HumanSignal/label-studio/pull/6724), [#6657](https://github.com/HumanSignal/label-studio/pull/6657))

While you can use paginated multi-image labeling with any series of related images, it can be especially useful for for document annotation. 

For example, you can pre-process a PDF to convert it into image files, and then use the pagination toolbar to navigate the PDF. For more information, see our [Multi-Page Document Annotation template](https://labelstud.io/templates/multi-page-document-annotation).

To enable this feature, use the `valueList` parameter on the [`<Image> tag`](https://labelstud.io/tags/image).

## ✅ Enhancements

### ✂️ Edit regions when classifying video frames

We recently introduced the ability to perform video frame classification with the [`<TimelineLabels>` tag.](https://labelstud.io/tags/timelinelabels)

You now have the ability to edit the frame spans you select in the timeline editor, making it easier to control which frames you want to label. ([#6577](https://github.com/HumanSignal/label-studio/pull/6577))

- When clicking the version link to update Label Studio, you will now be redirected to a Label Studio page rather than the PyPI release history. ([#6659](https://github.com/HumanSignal/label-studio/pull/6659))
