The latest release of a base Python library, along with updates for framework-specific libraries for FastAPI, Flask, and Django Rest Framework, introduces significant changes, including enhanced typing support and new APIs. The update improves type hinting, transforming responses from dicts to explicit datatypes, which may result in breaking changes for certain usage patterns. Enhancements to the User class allow for more straightforward permissions checking and easier mocking/testing by enabling direct functions on the User object. The release also includes new APIs for managing user sessions, setting up SAML links, and handling pending invites, alongside a feature gating example that demonstrates programmatically enforcing permissions based on subscription plans using role mappings. These updates aim to streamline user authentication and permissions management, especially during critical growth phases for B2B SaaS companies, by allowing seamless integration of advanced features like SAML and SCIM without complicating code structure.
