### [`v24.3.0`](https://github.com/hynek/structlog/blob/HEAD/CHANGELOG.md#2430---2024-07-17)

[Compare Source](https://github.com/hynek/structlog/compare/24.2.0...24.3.0)

##### Added

-   Restore feature parity between `structlog.traceback.ExceptionDictTransformer` and Rich's traceback extractor:

    -   When displaying locals, use Rich for formatting if it is available.
    -   When displaying locals, call `repr()` on strings, too (improves handling of `SecretStr` implementations).
    -   Add `locals_max_length` config option
    -   Add `locals_hide_sunder` config option
    -   Add `locals_hide_dunder` config option
    -   Add `suppress` config option

    [#&#8203;627](https://github.com/hynek/structlog/pull/627)

##### Changed

-   `structlog.testing.capture_logs()` now maps the `exception` log level to `error` (as it's elsewhere).
