October 2024: Implemented a targeted fix in the FreeCAD/FreeCAD expression parser to enforce base-10 integer parsing and eliminate octal interpretation of numbers with leading zeros. This ensures literals like '010' are parsed as 10, improving correctness and predictability of numeric expressions used in CAD models and scripting. The change reduces parsing errors in user workflows and decreases support overhead related to numeric literals. The work is captured in commit 19fa91253fbcaae7d8786a0fc85d83e31d615bb7 with message 'Remove octal in expressions when there's a leading zero'.
