> **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 - .NET 1.4.1

## New functionality

### TLS 1.0, 1.1 and 1.2 supported

Communication with the payment device using TLS 1.2 is supported. If the payment device supports it this version is chosen by default.

### Stores added

A terminal can be associated by default with a store by passing a `storeID` in the register PED call. `store` influences how transactions are routed and settled. 

### Updated .NET

The library now uses the 4.6.1 .NET framework.

## Improved functionality

### TxStore now asynchronous

The TxStore response is now asynchronous instead of synchronous. 

### Only TLS 1.2 supported

Communication with the PSP only supports TLS 1.2

### TxStore now includes multiple amounts

`TxStoreQuery` now supports multiple amounts to be returned. `amount` is the amount that will be settled to the merchant. In case of a DCC transaction, the `referenceAmount` will be the authorized amount in the shopper's currency. In case of a partially authorized transaction, the `referenceAmount` will be the original (full amount) that was requested by the POS.
