# Version 7.0.1 Changelog (August 27, 2019)

World's #1 PDF SDK Library for Web, Mobile, Server, Desktop

Version: 7.0.1.72303

Release Date: August 27, 2019

### New Features

* UI support for selection and editing of existing Annotation Groups. You can resize, change border and background color, change opacity, flatten the annotation group, delete the annotation group and ungroup the annotations.
* Updated API for Digital Signature creation (`DigitalSignatureField` and `DigitalSignatureIterator` classes).
* Programmatic, low-level Undo/Redo API. (`UndoManager`, `ResultSnapshot` and `DocSnapshot` classes)
* Added an in-memory interface for rendering individual separations. (`PDFDraw.GetSeparationBitmaps`and `PDFRasterizer.RasterizeSeparations`).
* Added extra modes to geometry snapping: snap to point on line, snap to midpoint, and snap to line intersection.
* Added Widget functions to Set/Get Text Color, Font and Font Size.
* New Widget API for form field creation/access. (`TextWidget`, `CheckBoxWidget`, `RadioButtonWidget`, `RadioButtonGroup`, `PushButtonWidget`, `SignatureWidget`, `ListBoxWidget` and `ComboBoxWidget` classes).
* Added utility functions to `ComboBoxWidget` and `ListBoxWidget` which simplify reading and editing options. (`GetOptions()`, `ReplaceOptions()` and `RemoveOption()`)
* Added an API allowing sound annotations to be created from raw sound data. (`Sound.CreateWithData`).
* New method for easily rotating an annotations appearance by an arbitrary angle.

### Changed Behavior:

* ToXod default options have been changed. The XOD default setting for flattening is now `e_high_quality` (previously `e_fast`) and the default setting for line thickening is false. (previously true).
* The GDI+ Rasterizer has been marked as deprecated and will be removed in a future version of our SDK.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.apryse.com/uwp/changelogs/version-7/v7-0-1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
