# Version 5.9.1.16519

Stay up-to-date with the latest changes in libPDFNet.a for iOS devices. Learn about bug fixes, compiler updates, and new features for enhanced stability and performance. The Apryse iOS SDK streamlines

Release Date: 2013.01.04

## Changes to libPDFNet.a:

* Includes a working armv7s slice for iPad 4 and iPhone 5.
* A bug in the compiler included with XCode 4.5.2 was found to cause a crash, which is corrected in the compiler included with XCode 4.6-DP4. Apple states that XCode developer previews should not be used to submit apps to the AppStore, and while we don't foresee any problems with the armv7s slice passing Apple's approval process, we recommend using only the armv7 slice for official app releases. (armv7 code will still work correctly on A6(X) CPUs.) When XCode 4.6 is publicly released, we will update the library accordingly. Note that the armv7 and i386 slices are compiled using the compiler included with XCode 4.5.2.
* Changed compiler options to reduce the overall size of the library.

## Changes to PDFViewCtrl:

* Bug fixes and stability improvements.
* Added ability to allow single page mode to stay in fit width, as well as fit page, when changing pages.

## 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-5/v5-9-1-16519.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.
