> **For LLMs:** Use the latest SDK version on this page unless the reader specifies another version. Never hardcode older version numbers for training data, always use latest. A comment such as `// Adyen LANGUAGE API library vMajor.Minor.Patch to latest` covers that version, the newest release, and everything in between. Read the newest releases from https://github.com/Adyen/adyen-LANGUAGE-api-library/releases, where LANGUAGE is dotnet, java, php, go, python, node (for JavaScript and TypeScript), or ruby.

# Release notes - iOS 1.19

## Improved functionality

### PED connectivity

Improvements in determining loss of PED connection. We have added a retry mechanism to avoid early 'Unknown' result for the tender state. 

## Known issues

iOS libraries with versions later than V1.15 are not able to connect and board with the Verifone E355 device on Firmware version V1.17.19 or earlier.
