May 2025, Kratos: Delivered two strategic feature streams accelerating build reliability and Python packaging quality, with measurable business value. 1) Release Management and Build Environment Modernization: reworked the release pipeline and wheel-building stack, bumped versions, refreshed the Docker wheel-builder image, and aligned with manylinux2014 and updated CMake policies to improve build reliability and packaging quality. This enhanced wheel availability across platforms, reduced build churn, and simplified downstream integration. 2) Python Version Compatibility and Packaging Overhaul: consolidated the Python version strategy to support Python 3.13 and 3.14, set 3.13 as default for core builds, refined version resolution, and improved packaging scripts and setup classifiers to reflect supported interpreters. These changes position Kratos for broader Python ecosystem compatibility and smoother packaging upgrades. Overall impact: faster, more reliable builds; easier maintenance; clearer interpreter support; improved packaging quality across distributions. Technologies: Python packaging, multi-version support, Dockerized wheel builds, manylinux, CMake policy, build automation, and metadata management.
