<summary>v1.0.0</summary>

<mark style="background-color:purple;">**Released on**</mark> <mark style="background-color:purple;"></mark><mark style="background-color:purple;">02/25/2026</mark>

Added the various authentication methods:

* basic authentication
* bearer token authentication
* API key authentication
* Added an *error* port when this Listener is used in a pipeline in order to eliminate data loss when an error occurs.&#x20;
* You can now capture and forward all HTTP headers from incoming requests by selecting **All** in the **Propagate headers strategy** configuration. When enabled, Onum automatically collects all request headers and makes them available in a consolidated **headers** field, preserving the complete header context throughout the processing pipeline without requiring manual specification of individual header names.
* The default header propagation strategy is back to **None**.
* Header names in the configuration are automatically converted to canonical form.&#x20;
