# Version 7.1.0.74186 Changelog (February 27th, 2020)

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

* Version: 7.1.0.74186
* Release Date: February 26th, 2020
* Built with Xcode 11.3.1 (11C505)

## New

* Support for multiple saved signatures.
* Ability to scroll and zoom while drawing with PencilKit.
* A new freehand highlighter tool. This uses "multiply blend" to ensure dark PDF content remains dark, and is particularly useful when highlighting scanned documents.
* Support for [viewer-optimized PDFs](/ios/optimization/viewer-optimized.md), where a remote document can be loaded in \~3 seconds, regardless of size or page complexity.
* Support for viewing XPS and [XOD](/web/custom-server/custom-server-deployment.md#overview) files. (XOD is a web-optimized file format used by some deployments of [WebViewer](/web/get-started/guides.md)).
* Automatic initialization: it is no longer necessary to call PDFNet.initialize on startup when running in demo mode. (It is still required to register a purchased license key.)
* Core cross-platform improvements including:
  * Digital signature verification.
  * Much improved conversion quality for PPT files, and improved conversion quality for all other Office file formats.
  * And [much more...](/core/changelogs/version-7/7-1-0.md)

## Known Issues

When PDFNet is auto-initialized into demo mode by default, a console message will be printed which appears to indicate that the commercial license key used with `PTPDFNet.initialize()` is invalid:

{% tabs %}
{% tab title="Shell" %}
{% code lineNumbers="true" %}

```sh
Failed to initialize Apryse: Exception: 
  Message: Bad License Key. PDFNet SDK will work in demo mode. For more
information please see https://community.apryse.com/t/license-key-exception/3376
Conditional expression: 
Version      : 7.1.0.74186
Platform     : iOS
Architecture : Arm
Filename     : 
Function     : 
Linenumber   : 0
...
```

{% endcode %}
{% endtab %}
{% endtabs %}

This message is currently part of the PDFNet auto-initialization process and can be ignored. It will be fixed in the next official release of the SDK.

If you are using a commercial license key, your key will be applied correctly and no watermarking on pages will appear.

## 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/ios/changelogs/version-7/v7-1-0-74186.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.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
