* 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

# Agent Instructions
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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.apryse.com/ios/changelogs/version-6/v6-8-0.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
