+### Facet keys now always use the full relationship chain

+In `v2`, relationship facet fields used only the terminal column key (e.g. `"name"` for `Role.name`) and only prepended the relationship name when two facet fields shared the same column key. In `v3`, facet keys **always** include the full relationship chain joined by `__`, regardless of collisions.

 ## Models
 
 The lifecycle event system has been rewritten. Callbacks are now registered with a module-level [`listens_for`](../reference/models.md#fastapi_toolsets.models.listens_for) decorator and dispatched by [`EventSession`](../reference/models.md#fastapi_toolsets.models.EventSession), replacing the mixin-based approach from `v2`.

 ## Cleaning up tables
 
-!!! warning
-    Since `V2.1.0` `cleanup_tables` now live in `fastapi_toolsets.db`. For backward compatibility the function is still available in `fastapi_toolsets.pytest`, but this will be remove in `V3.0.0`.
-
 If you want to manually clean up a database you can use [`cleanup_tables`](../reference/db.md#fastapi_toolsets.db.cleanup_tables), this will truncate all tables between tests for fast isolation:
