Month 2025-11 — KDAB/KDUtils: Formatting API updated to be const-correct for compatibility with fmt 12.0.0. This change fixes a const-correctness bug and improves reliability of the formatting API for downstream usage. Patch applied and aligned with fmt ecosystem expectations (commit: 4d403c0ecae21815600ca5e2602da4afbc818ad4).

October 2025 KDUtils monthly summary: Migration of dependency management to vcpkg, with CMake integration, delivering more robust build reproducibility and cross-platform consistency. Core libraries (spdlog, KDBindings, whereami, mio, mosquitto) are now resolved via vcpkg, reducing manual maintenance and minimizing drift across environments. Submodule-based approach via .gitmodules ensures vcpkg availability in CI and local builds. No customer-facing bugs fixed this month; primary impact was stabilizing the build system and accelerating onboarding for new contributors.

May 2025 monthly summary for KDAB/KDUtils focused on strengthening object lifecycle safety and expanding API flexibility. Key changes include refactoring destruction_helpers.h to remove the global namespace usage (KDBindings), which improves header hygiene and reduces collision risk, and adding unit tests and documentation to bolster reliability of object destruction. Additionally, Object::createChild was extended to accept constructor arguments by reference, with ObjectThatTakesInRef and corresponding tests verifying child construction using references to existing parent objects. These efforts increase safety, reliability, and maintainability while broadening API expressiveness.

Month: 2025-04 – KDUtils developer work focused on code hygiene and CI quality improvements. Delivered a targeted change to suppress the [nodiscard] warning on KDBinding::Signal::connect when connecting to a property's signal, ensuring the connection handle is not unnecessarily tracked while the property remains valid. This change reduces build noise and aligns with maintenance goals without altering runtime behavior.
