# Notable fixes and improvements

## CLI

- New guided process to create a Workspace using the CLI. Also improved inline help for Workspace creation. Go try 'tb workspace create –help'
- We've fixed an issue with the 'tb fmt' CLI command to format queries. If your Pipe had versioning, it was removing the VERSION 0 line on formatting.

## Data Sources and Data Sources UI

- It is now easier to inspect the columns of the [Service Data Sources](/forward/monitoring/service-datasources) when working from the Pipe editor or Time Series editor.
- We are now displaying the pulse graph also for materializations coming from Kafka Data Sources.
- Users won’t be offered the option to delete Shared data sources under the "Clean up" section.
- Now you can modify existing JSONPaths in data source columns, or add new columns with JSONPaths using the [data source alter API](/api-reference/datasource-api#post--v0-datasources-(.+)-alter).
- Improved error messages when problems arise adding a column to the Data Source via the UI.
- The UUID type is now available to choose when defining a new Schema via the UI.

## Other notable changes

- We've introduced 30 days option in the Time Series granularity selector. 
- Added support for arbitrary (non UTF-8) bytes in Kafka message keys when using Schema Registry.
