* New methods to [customize the UI tools](/ios/annotation/customization.md) without modifying the tools source code.
* iPhone X support for UI controls
* Improved sample projects, including a new set of Swift samples
* Documentation for Tools.framework
* RTL support for free text annotations

### Breaking changes

* [`PDFNet.initialize`](https://sdk.apryse.com/api/ios/Classes/PTPDFNet.html#/c:objc\(cs\)PTPDFNet\(cm\)Initialize:)**no longer** accepts null or empty license keys. **A valid demo or commercial license key is required at all times.** Please request a trial license if you do not have one.
* Direct office conversion is not included for 32 bit platforms in the standard distribution. (If you use a direct office conversion on a 32 bit platform, it will throw an exception.) Licensed customers can contact us at <support@apryse.com> if they require this functionality.
* `TRN_rect` is no longer available, use `PTPDFRect` instead. For this reason, use `-[PTPDFRect GetX1]`, not `-[PTPDFRect getX1]` (etc.).
* A number of improvements have been made to `Tools.framework`, including some which will require updates to your app's code. Please see the guide [6.7 to 6.8 Migration](/ios/guides/changelog/resource/6-7-to-6-8-tools-framework-migration.md).

### Bug fixes

* Miscellaneous bug fixes and minor improvements

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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-6/v6-8-0.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.
