## UNRELEASED

## 1.2.0, 2026-06-08

### Improvements
- SQLAlchemy: opt-in server-side bind parameters via `create_engine(url, server_side_params=True)`. The dialect then emits ClickHouse native `{name:Type}` / `{name:Array(Type)}` placeholders instead of client-side string interpolation. Off by default. Closes [#735](https://github.com/ClickHouse/clickhouse-connect/issues/735).
- Added a `token_provider` client option (sync and async). It accepts a callable returning an access token string; the callable is invoked once for the initial token and again to fetch a fresh token whenever the server rejects the current one (authentication failure), retrying the request once. Mutually exclusive with `access_token` and `username`/`password`.
