### **Important Notes:**  
This update *might* require regenerating your database types. You can do this via the Supabase CLI (≥[v1.207.8](https://github.com/supabase/cli/releases/tag/v1.207.8)) or the dashboard. For instructions, check out our guide [here](https://supabase.com/docs/guides/api/rest/generating-types).

### **Potential Issues**  
This version introduces stricter alignment between runtime behavior and type inference. As a result, some types might appear "broken" but are actually being corrected.  

The main changes to be aware of:  
1. The result of an embedding now correctly infers a single object or an array based on the relationship.  
2. The result of an object embedding now more accurately identifies whether the result can be `null`.  

Before reporting a bug, please double-check that the inferred types are truly incorrect based on your query and database schema.

### **Bug Reporting:**  
If your project is hosted on Supabase, please open a support ticket [here](https://supabase.com/dashboard/support/new) and check "Allow Supabase Support to access your project temporarily." This will enable us to investigate your database types directly.  

Alternatively, you can open an issue on [GitHub](https://github.com/supabase/postgrest-js). Please include:  
1. The generated `Database` type used to instantiate the client (e.g., `createClient<Database>(process.env.SUPABASE_URL, process.env.SUPABASE_ANON_KEY)`).  If possible a minimal `SQL` declaration resulting in such `Database` type.
2. The query where type inference failed (e.g., `.from('which-table').select('which-query')`).  
3. Your TypeScript version (`npx tsc -v`).
