# 6.12.2

## Features

### REST connector: Improvements

#### Iterator

Connector now supports the use of an iterator.

#### OpenAPI 3 

OpenAPI version 3 files can now be imported

#### Operation 

Designer New way to design and test your operations. Similar to Postman.

#### Model parser 

Tool to test your models with given json or xml. Useful for debugging issues with your models.

#### Link operations 

Use the result of one rest operation as input to another operation. For example can one operation be used to fetch a token, which can be used in the next operation.

#### Configuration parameters 

Enabled parameters to be configures outside of the connector tool, in the connector configuration. For instance secrets used to fetch tokens.

#### Computed parameters 

Compute (using c#) what the value a parameter should have, based on other parameters of the operation, configuration parameters or the output of a linked operation.

#### Minor changes 

* Improved assistance when debugging (better logfiles for instance) 
* Copy parameters between operations 
* Rearrange and sort model members

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.novacuraflow.com/6.12/release-notes/6.12.2.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
