# Release notes - iOS 1.17

We're pleased to announce a new iOS library that makes integration with our Payment Terminals quicker and easier. 

## Improved functionality

### Download firmware in background

Improved support for downloading payment device firmware in the background. 

### Dynamic framework

The iOS library is now a dynamic framework. Bundle resources are contained within a single \*.framework package.

### Documentation

We've improved the included API Reference documentation.

## Removed functionality

Removed barcode scanning functionality. A dedicated barcode scanning library is available at <https://github.com/Adyen/adyen-barcoder-ios>

Our barcode scanning library is compatible with terminal firmware versions 1\_17p19 and later.  

## Fixed issues

* Previously, for a small number of merchants, when a terminal restarted the barcode functionality was disabled. This is now fixed.

## Known issues

* Connection issue for terminals with on-screen signature, connected to an iOS device using Wi-Fi:\
   After five transactions, the connection is lost between the terminal and iOS device. This results in an 'UNKNOWN' status.\
  **Workaround:**

  * Wait a few seconds, and the connection will re-establish.
  * Check the txStore to make sure the transaction went through.
  * If you encounter this error, contact [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other) and we can add a workaround in the Adyen payments platform.
