# Spaces Changelog ## [2026-03-18] - Protected Spaces visibility - Spaces now support a **protected** visibility option, in addition to public and private. In Space settings, visibility is now set through a dropdown with three options instead of a simple public/private toggle. - Protected visibility is available on [PRO](https://huggingface.co/pro) and [Team & Enterprise](https://huggingface.co/enterprise) plans. - A protected Space keeps its source code private on the Hub, while the app remains publicly accessible through its embed URL or [custom domain](./spaces-custom-domain). - This is especially useful for hosting websites without publishing source code. - Read more in the [Spaces Overview](./spaces-overview#space-visibility). ## [2025-04-30] - Deprecate Streamlit SDK - Streamlit is no longer provided as a default built-in SDK option.
