July 2025: Delivered two essential bug fixes in termux-packages that enhance build reliability and security. SwiftShader build script compatibility with CMake 4 was addressed, and OpenSSL was upgraded to 3.5.1 with outdated patches removed and version/SHA256 updated. These changes improve cross-environment build stability, reduce maintenance drift, and strengthen the security posture for downstream users. Techs demonstrated: CMake-based build fixes, patch management, versioning, and secure dependency upgrades.
