# 13.26.0

**Release date 29-04-2026**

## New Features

* **Support configuration of PDF archive methods**

  The documenten-api-preview plugin now supports configuration of PDF archive methods. PDF archiving is turned off by default, but administrators can enable PDF archiving via the plugin configuration.

## Enhancements

* **Explanatory loading message**

  The documenten-api-preview plugin will now show an explanatory loading message, above the loading spinner, when converting a document to a preview.
* **IKO Search FormIO component**

  A new custom FormIO component allows case workers to search and select an IKO result directly inside a user task form. When a result is selected, the ID and any configured property values from the search result table are written to the case document as a single object. This data can then be used in subsequent process steps or displayed in case widgets using `doc:` value resolver paths, removing the need for additional IKO API calls at display time. See [Search FormIO component](/features/iko/search-formio-component.md) for configuration details.

## Enhancements

* **Improved REST client error logging security**

  The `LoggingRestClientCustomizer` no longer includes request and response bodies or headers in exception messages. Previously, when an external REST call returned an error status, the full request report — including potentially sensitive data such as tokens, API keys, or personal information — was embedded in the `HttpClientErrorException` message. This could cause sensitive data to leak into error handlers, monitoring tools, or API responses.

  The detailed request and response information is now only available at `DEBUG` log level, which is typically disabled in production. The exception itself only contains the HTTP status code and status text. See [REST client logging](/features/logging/for-developers.md#rest-client-logging) for configuration details.
