# Lots of query parameter improvements!

We've significantly improved how to work with query parameters, with autocompletion for parameters, a side panel for parameters editing, and SQL parameters editing.

### Parameters autocomplete

The query editor now autocompletes parameters while in Python or parameters' blocks. For each parameter you can see its type and other useful information.

### Side panel for testing

You can now test parameters in a convenient side panel, so that it doesn't cover your queries or other UI elements as it sometimes happened before.

### SQL editing with parameters

You can now edit your SQL queries while testing parameters in Pipes. Previously, Pipes were read-only when working in test mode, but now you can modify both the SQL and the parameters.

## Usage charts for dedicated infrastructure plans

If you're on a dedicated infrastructure plan, you can now check the usage of key resources on your cluster, as well as performance indicators. See the new charts under **Organization settings, Usage**.

## Prometheus format for Pipe endpoints

[Prometheus format](/api-reference/pipe-api#get--v0-pipes-(.+)\.(json|csv|ndjson|parquet|prometheus)) is now available for API Endpoints. [Integrating Tinybird data with you preferred monitoring and alerting tools](/forward/guides/consume-api-endpoints-in-prometheus-format) is now easier.

## Improved previews for S3 Connector

We enhanced S3 bucket traversal for previews. This improvement lead to faster previews and provide more detailed error messages. 

## Improvements and bug fixes

- Improved the tooltip that informs users that a Workspace is read-only in the UI.
- Fixed an issue where the X axis of a chart wasn't ordered alphabetically when using a string field like "Jun - 2024"
- Fixed a bug where engine settings weren't being propagated when editing the Data Source properties using the code editor.
