February 2026 (2026-02): Vector35/debugger — Delivered a critical bug fix for TTD Memory Widget Display Correctness for Wide Values. Resolved undefined behavior when handling values wider than 8 bytes by adjusting the display logic to mask values according to access size. This ensures correct rendering up to 8 bytes and prevents the prior 0x0 misrepresentation, aligning with TTD’s return behavior of 8-byte Value fields. The change improves memory visualization reliability across platforms and reduces confusion during debugging.
