 *  **Timeouts now default to 10 seconds.** Previously we defaulted to never
    timing out, and that was a lousy policy. If establishing a connection,
    reading the next byte from a connection, or writing the next byte to a
    connection takes more than 10 seconds to complete, you’ll need to adjust
    the timeouts manually.

 *  **OkHttp now rejects request headers that contain invalid characters.** This

    SQLModel will know that something declared as `str` will be a SQL column of type `TEXT` (or `VARCHAR`, depending on the database).

### Create an Engine { #create-an-engine }

A SQLModel `engine` (underneath it's actually a SQLAlchemy `engine`) is what **holds the connections** to the database.
