 - `encrypt` - Whether to encrypt the connection. For example, `true`.
 - `sslValidateCertificate` - Whether to validate the SSL certificate. For example, `true`.
 - `key`, `cert` and `ca` - Private key, public certificate and certificate authority for the encrypted connection.
+- `driver` - Optional explicit `@sap/hana-client` module instance. If omitted, TypeORM loads `@sap/hana-client` automatically.
 - `pool` — Connection pool configuration object:
     - `maxConnectedOrPooled` (number) — Max active or idle connections in the pool (default: 10).
     - `maxPooledIdleTime` (seconds) — Time before an idle connection is closed (default: 30).
     - `maxWaitTimeoutIfPoolExhausted` (milliseconds) - Time to wait for a connection to become available (default: 0, no wait). Requires `@sap/hana-client` version `2.27` or later.
     - `pingCheck` (boolean) — Whether to validate connections before use (default: false).
     - `poolCapacity` (number) — Maximum number of connections to be kept available (default: no limit).
 
+Removed legacy aliases: `hanaClientDriver`, `pool.max`, `pool.requestTimeout`, `pool.idleTimeout`, `pool.min`, `pool.maxWaitingRequests`, and `pool.checkInterval`.

@@ -14,6 +14,21 @@ TypeORM requires newer versions of the database client libraries.
 
 The `connectorPackage` option was removed, together with the support for the old `mysql` client. The only database client supported is now `mysql2`, which TypeORM will try to load by default. If you were using `mysql` in your project, simply replace it with `mysql2`.
 
+## SAP HANA
+
+Several deprecated SAP HANA connection aliases were removed.
+
+- `hanaClientDriver` was removed. Use `driver`.
+- `pool.max` was removed. Use `pool.maxConnectedOrPooled`.
+- `pool.requestTimeout` was removed. Use `pool.maxWaitTimeoutIfPoolExhausted`.
+- `pool.idleTimeout` was removed. Use `pool.maxPooledIdleTime` (seconds).
+- `pool.min`, `pool.maxWaitingRequests`, and `pool.checkInterval` were removed with no replacement.
+
+Also note the default behavior changes in pool configuration:
+
+- `pool.maxPooledIdleTime` now defaults to `30` seconds and no longer falls back to `pool.idleTimeout`.
+- `pool.maxWaitTimeoutIfPoolExhausted` now defaults to `0` and no longer falls back to `pool.requestTimeout`.
+
 ## SQLite
 
 Drop support to `sqlite3` in favour of `better-sqlite3` as the primary driver for `sqlite` databases:
