During September 2025, Ak worked on the amnezia-vpn/amnezia-client repository, delivering a patch release that incremented the application version to 4.8.10.1 and updated the Android versionCode to 2094. Focusing on build system management, Ak used CMake to ensure a stable and compatible upgrade path for users, emphasizing release engineering best practices. Although no major bugs were addressed during this period, the work laid a solid foundation for future feature development by maintaining clear traceability and version control. The depth of the contribution was in process reliability, with careful attention to release workflows and build system consistency across platforms.
