# 1.2.1.0 (ID Authentication)

## Release Notes

**Release Version**: 1.2.1.0

**Release Date**: 3rd May 2024

We're excited to announce a significant enhancement geared towards refining the authentication process within our system. This improvement targets the seamless resolution of UIN / VID-related errors encountered by users during authentication attempts. This release also includes a fix of a critical bug related to ID Authentication.

**Major Areas of Work**

* ID Authentication

**New feature**:

* **Authentication Error Eventing**: Users registered with a valid UIN / VID can proceed with authentication seamlessly. In cases where an error arises due to the unavailability of UIN / VID during authentication, application prompts a message to retry after a few minutes. Simultaneously, the Kafka event will be triggered to publish the data to the topic, and subscribers will receive a message for subsequent processing. You can refer [here](https://docs.mosip.io/1.2.0/modules/id-authentication-services#authentication-error-eventing) for further information.

  **Note**: This feature will exclusively be accessible in ID Authentication version 1.2.1.0. Users are required to set up this latest version on their existing platform version 1.2.0.x.

### Bug fix

* During the authentication process, if the `authStatus` is false, the `authToken` should not be shared. However, there was an issue where the system was sending the authToken value even when the `authStatus` was false. This issue has been addressed and fixed. Now, when the `authStatus` is `false`, the `authToken` will no longer be shared. [#MOSIP-30293](https://mosip.atlassian.net/browse/MOSIP-30293).

## 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.mosip.io/1.2.0/roadmap-and-releases/releases/1.2.1.0.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.
