Jul 1, 2025Monthly summary for 2025-07 focused on angr/angr. Delivered a robust fix to JumpTableResolver for external default targets by analyzing the function's transition graph instead of the local graph when checking for two successors, improving correctness in control-flow resolution. Added test coverage to guard against regressions for external default targets. The work aligns with issue #5611 and is supported by commit 178357272f7dd8963efb170c18b324847879fd66.
