- The `get_config_form()` method is now optional when implementing an enrichment, as previously incorrectly described in the documentation. [44](https://github.com/datasette/datasette-enrichments/issues/44)

- Removed `breakpoint()` calls in an error path that should not have been released. [49](https://github.com/datasette/datasette-enrichments/issues/49)

- New utilities for developing enrichments that need to be [configured with secrets](https://enrichments.datasette.io/en/stable/developing.html#enrichments-that-use-secrets-such-as-api-keys) such as API keys, taking advantage of the [datasette-secrets](https://datasette.io/plugins/datasette-secrets) plugin. [#46](https://github.com/datasette/datasette-enrichments/issues/46)

- Handle case where no enrichments plugins are installed. [43](https://github.com/datasette/datasette-enrichments/issues/43)
