 Announcing the release of Spice v1.1.2! 🔗  
 
 Spice v1.1.2 improves Delta Lake Data Connector performance, introduces new Accept headers for the `/v1/sql` and `/v1/nsql` endpoints to include query metadata with results, and resolves an issue with the Snowflake Data Connector when handling wide tables (>600 columns).
