+- **Enhancement**: Introducing a revamped overview page for dbt Explorer, available in beta. It includes a new design and layout for the Explorer homepage. The new layout provides a more intuitive experience for users to navigate their dbt projects, as well as a new **Latest updates** section to view the latest changes or issues related to project resources. To learn more, refer to [Overview page](/docs/collaborate/explore-projects#overview-page).
 - **Enhancement**: The dbt Semantic Layer now offers more granular control by supporting multiple data platform credentials, which can represent different roles or service accounts. Available for dbt Cloud Enterprise plans, you can map credentials to service tokens for secure authentication. Refer to [Set up dbt Semantic Layer](/docs/use-dbt-semantic-layer/setup-sl#set-up-dbt-semantic-layer) for more details.
 - **New**: Introduced the [`dbt-sl-sdk` Python software development kit (SDK)](https://github.com/dbt-labs/semantic-layer-sdk-python) Python library, which provides you with easy access to the dbt Semantic Layer with Python. It allows developers to interact with the dbt Semantic Layer APIs and query metrics and dimensions in downstream tools. Refer to the [dbt Semantic Layer Python SDK](/docs/dbt-cloud-apis/sl-python) for more information.
 - **New**: The ability to lint your SQL files from the dbt Cloud CLI is now available. To learn more, refer to [Lint SQL files](/docs/cloud/configure-cloud-cli#lint-sql-files).
