## **Connectors**

### **LLM connector update**

The **LLM** connector now allows you to:

* Add and configure a remote MCP server on the **Tools** tab in the configuration form.
* Test the execution of the configured connector in isolation, without executing the full pipeline.

These improvements give you more flexibility to integrate external resources and speed up development by making it easier to configure, test, and validate the connector.

### **Marketo connector update**

The **Marketo** connector has received updates to improve usability, including:

* Support for the [Previous Steps Access](https://app.gitbook.com/s/EKM2LD3uNAckQgy1OUyZ/double-braces/how-to-reference-data-using-double-braces/previous-steps-access) feature.
* Renaming the parameter from **APIs** to **BaseURLs**.
* Updated connector icon.

### **New string function: `CONCATWITHOUTTAB`**

The new `CONCATWITHOUTAB` function allows you to concatenate two or more strings, replacing all tab characters `(\t)`  with a single space (" ").

## **Documentation**

We’ve updated the following documentation:

* [Autoscaling](https://app.gitbook.com/s/jvO5S91EQURCEhbZOuuZ/development-cycle/overview/runtime/autoscaling)
* [DB V2](https://app.gitbook.com/s/EKM2LD3uNAckQgy1OUyZ/connectors/structured-data/db-v2)

## **Improvements and bug fixes**

### **Improvements**

* **Canvas optimizations:** We’ve optimized Canvas performance to deliver a more seamless and responsive workflow experience.

### **Bug fixes**

* **“Code” field type doesn’t keep the value as a JSON object when executing the capsule:** We fixed the bug where JSON fields configured as “Code” inside capsules were incorrectly converted into strings, causing inconsistencies between capsule mocks and pipeline mocks.
* **Unrelated alias connectors displayed in autocomplete:** We fixed the bug that showed unrelated alias connectors in autocomplete even when they have no direct connection to the current connector.
