# [2022-02-08] Nylas API v2.4

Source: https://developer.nylas.com/docs/new/v2-release-notes/2022-02-08-nylas-api-v2-4/

We released version 2.4 of the Nylas API.

This is a breaking change from version 2.3.0.

## Changes

We fixed an issue where Microsoft authentication errors were returned as plain text. Now they return as a JSON object.

```json
{
  "message": "You've entered invalid credentials",
  "type": "auth_error",
  "error": "Wrong username or password for https://outlook.com/EWS/Exchange.asmx"
}
```
