Feb 1, 2026February 2026 (2026-02) — Key achievements in conan-center-index: delivered a major dependency refresh with publishing cleanups and platform compatibility improvements. Updated core libraries: OpenAPV 0.2.1.0, OpenImageIO 3.1.10.0, LibVPX 1.16.0, LibJXL 0.11.2, ImPlot 0.17. Implemented LibVPX platform handling to require yasm only on x86/x64 builds, reducing build tooling on non-x86 architectures. Stopped publishing new revisions for older LibJXL versions to improve release hygiene. These changes reduce build complexity, improve cross-platform compatibility, and provide downstream users with up-to-date, secure libraries.

Aug 1, 2025August 2025: Delivered a focused set of dependency updates in Conan Center Index to refresh core libraries and improve build reliability across platforms. Key updates include OpenH264 2.6.0, OpenJPH 0.22.0, ImGui 1.92.2b, and Imath 3.2.1, each with new source URLs and SHA256 checksums, and registered in config to enable building. Implemented cross-platform packaging improvements by removing hard-coded CXX standard and fPIC flags where appropriate and adopting Conan auto_shared_fpic for cross-platform compatibility. Aligned versioning and packaging in conanfile.py to reflect newer releases, reducing maintenance burden and enabling downstream projects to consume up-to-date dependencies. No critical bug fixes recorded this month; however, these updates reduce risk, improve reproducibility, and unlock performance/feature gains for downstream users.
