During January 2026, Athos Ribeiro enhanced the Cacti/cacti repository by implementing PHP 8.5 compatibility and improving XML parsing reliability for production environments. He addressed deprecated PHP features by replacing the backtick operator with shell_exec, modernizing case statement syntax, and introducing version checks for XML parser functions. His work focused on backend development using PHP and XML parsing, aligning with the project's PHP upgrade roadmap. While the contribution was limited to a single feature and did not include bug fixes, Athos demonstrated a methodical approach to code modernization, ensuring the application remains robust and maintainable as it transitions to newer PHP versions.
