March 2026 monthly summary for pymc-devs/pymc: Delivered a critical broadcasting compatibility fix for log_prob and Jacobian computations in Half distributions, improving reliability for HalfStudentT and HalfCauchy models and broadening applicability in probabilistic modeling. The change ensures correct broadcasting behavior across log probability and Jacobian determinant, preventing runtime broadcasting errors in edge cases.

January 2026 monthly summary for streamlit/streamlit focusing on authentication and session management improvements, with targeted fixes to enhance multi-dashboard hosting, logout behavior, and test coverage.

December 2025 monthly summary focusing on key features and impact for streamlit/streamlit. Delivered a secure OIDC token handling feature by storing tokens in a dedicated cookie and exposing them through the st.user interface, with cookie chunking to support large user data. Implemented a robust token delivery path that is decoupled from user info storage, enabling reliable API calls with tokens while addressing browser cookie size limits. Unit tests were added and manual testing confirmed end-to-end behavior. This work closes key token-related issues and paves the way for future token refresh capabilities.

July 2025 monthly summary for streamlit/streamlit focusing on identity management improvements. Delivered OpenID Connect (OIDC) logout enhancement to enable complete sign-out from identity providers by leveraging the end_session_endpoint. Also stores the provider name in the session cookie to improve logout tracing and user experience. This feature aligns with security, compliance, and UX goals while minimizing risk to existing logout flows.

April 2025 monthly summary for AllenDowney/pymc focusing on feature expansion and quality improvements. Delivered a generalized Ordered transform to support positive values and customizable order (ascending/descending). Updated the core transform methods (forward, backward, and log_jac_det) to accommodate new parameters while preserving backward compatibility. Implemented targeted tests to verify positive value handling and different ordering scenarios, increasing reliability for constrained modeling and inference workflows.

March 2025 monthly performance: Delivered key feature enhancements to PyTensor's transpose input path, enabling numpy arrays as input for the pattern argument and expanding tests to cover tuples, lists, and numpy arrays; fixed transpose numpy compatibility (#1142); expanded test coverage to ensure reliability; overall impact includes improved interoperability with numpy-based workflows and a more maintainable codebase.
