June 2025: Delivered cross-repo improvements that strengthen stability, portability, and API compatibility across pyccel/pyccel and pyccel/psydac. Key efforts focused on expanding the LLVM toolchain, ensuring correct inout semantics, and maintaining compatibility with Pyccel 2.0.x. These changes improve performance potential on LLVM-based toolchains, reduce runtime errors due to incorrect inout annotations, and preserve seamless integration with downstream libraries.

March 2025-04 monthly summary focusing on Apple Silicon compatibility improvements and code quality for the Pyccel Psydac integration. Implemented dynamic CPU flag detection to support running Psydac on newer Apple Silicon (e.g., M4) and resolved a Python SyntaxWarning by using a raw string for a regular expression. These changes enhance cross-platform reliability, reduce potential runtime warnings, and improve maintainability for the Pyccel Psydac repository.

In March 2025, pyccel/psydac focused on correcting an edge-case in the B-spline collocation matrix calculation for a single Greville point. The fix ensures the collocation matrix returns a 1x1 matrix with value 1 for a single grid point, preserving expected behavior and preventing empty results that could disrupt downstream workflows. This change improves robustness and reliability of the collocation module with minimal risk and clear commit history. The patch is recorded in commit cb4955586901ec54b63bd12b86e53bdaad34fbcc as 'Fix Greville point collocation matrix for single grid point case (#446)'.
