## Guide content enhancements

* [Common Integration Use Cases](https://developer.paylocity.com/integrations/docs/common-use-cases-partners) updated to reference [Using Developer Portal](https://developer.paylocity.com/integrations/docs/using-developer-portal) documentation for renewing API credentials.

## API reference enhancements

* Added support for optional [business units](https://developer.paylocity.com/integrations/reference/business-unit), a new top-level hierarchy for [Background Check](https://developer.paylocity.com/integrations/reference/background-check-overview) configuration that can be associated with billing codes and/or packages. When associations exist, selecting a business unit filters the available billing codes and packages during ordering.
* Updated [Punch Import API](https://developer.paylocity.com/integrations/reference/punch-import-overview) documentation. The text is now more concise and clarifies that a maximum payload size of 500 objects is now enforced.
