This guide outlines the changes to Nutrient Android SDK 10.3.

## Breaking API changes

### Content editing text ID format

We changed how text IDs are handled in the content editing system:

- All text IDs used for content editing are now `String` values instead of UUIDs.

- This affects the method signatures in the [`ContentEditingManager.OnContentEditingContentChangeListener`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui.special_mode.manager/-content-editing-manager/-on-content-editing-content-change-listener/index.html) interface.

- It also impacts some classes, such as:
  - [`ContentEditingStylingBar`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui.contentediting/-content-editing-styling-bar/index.html)
  - Content editing undo-related classes

These changes are straightforward — if you were using UUIDs for text IDs, simply switch to using `String` values instead. If you haven’t interacted with these APIs directly, you’re likely unaffected.
