March 2025 monthly summary for angr/angr: Implemented a robust decompilation failure handling path in the Function class to prevent AttributeError when decompilation fails and the codegen is unavailable. The fix returns None for pseudocode in such failure cases, preventing crashes and preserving analysis continuity. This enhances reliability of the decompilation workflow and reduces downstream failures.
