# Modeler release 5.3.6.2

**Improvements**

* **AI agent model picker:** Preview models now have a "Preview" label. Preview models are meant for evaluation only and may be discontinued at short notice.
* **AI agent model picker:** Retired models are now hidden by default, like deprecated models. Turn on "Show deprecated models" to see them.
* **Publishing:** The Publish dialog warns you when AI agents use deprecated or retired models, so you can switch them to a supported model.
* **Publishing:** Projects that use AI agents must now publish all of their portals together, because all portals share the project's AI agents. The Publish dialog explains why when this applies.
* The SMTP option "Default WEM SMTP server" is now called "Default Runtime SMTP server".

**Fixes**

* Changes to task parameters, process parameter maps, assignments, data export maps, navigation parameters, web request headers, HTTP endpoint parameters, OData credentials and access rules, service definitions and security, and endpoint configurations are now applied to the preview straight away.
* Turning "Force download" on or off for a download-file action is now saved correctly.
* Dragging an AI agent conversation field onto a flowchart no longer leaves the flowchart editor in the wrong state.
* Fixed memory leaks when closing template editors that contain dropdowns, entity reference and concept inputs, custom controls or AI agent chat components.
* Fixed where the column resize handle appears in the template editor's data grid.
* The model field in field settings no longer shows a success indicator when there's nothing to report.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.wem.io/platform/release-notes/modeler-release/modeler-release-5.3.6.2.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
