# Diun v4.28 to v4.29

## Telegram `chatdIDs` and `chatIDsFile` attributes change

The `chatIDs` attribute has changed from a list of integers to a list of
strings. If you are using Telegram notifications, you need to update your
configuration file:

!!! example "v4.1"
    ```yaml
    notif:
      telegram:
        token: aabbccdd:11223344
        chatIDs:
          - 123456789
          - 987654321
    ```

!!! example "v4.29"
    ```yaml
    notif:
      telegram:
        token: aabbccdd:11223344
        chatIDs:
          - "123456789"
          - "987654321"
    ```

The same applies for the `chatIDsFile` attribute content:

!!! example "v4.1"
    ```json
    [123456789,987654321]
    ```

!!! example "v4.29"
    ```json
    ["123456789","987654321"]
    ```
