In October 2025, Gabriel Diaz updated the PennyLaneAI/pennylane repository to deprecate the custom_decomps argument in qml.device, steering users toward the qml.transforms.decompose workflow. He focused on technical documentation and migration guidance, using Python and reStructuredText to clarify the transition for developers. Gabriel added new sections explaining custom device decompositions and outlined best practices for adopting transform-based workflows, aiming to reduce future maintenance overhead. His work addressed the need for clear, actionable documentation during feature deprecation, ensuring that users could migrate smoothly. The update demonstrated depth in technical writing and a strong understanding of both the codebase and user needs.
