December 2025 monthly summary for gonicus/gonnect. Delivered robust, cross‑platform installer and packaging improvements, hardened runtime stability, and an enhanced build system, all designed to improve install reliability, onboarding, and cross‑platform maintenance. Key platform packaging work includes optional portal usage and refined NSIS configuration across Windows/macOS/Linux, with platform-specific adjustments and artwork assets. Also implemented resilient SecretPortal handling by making initialization tolerant when the portal is unavailable, preventing premature termination in non‑portal environments. Upgraded the Qt/runtime stack to enhance WebEngine stability and performance (base runtime 6.10, updated Qt, and related GPU/workaround fixes), and expanded build tooling with CMake workarounds and feature flags (GOW_002 for flatpaks, extension support). Introduced input preprocessing for better search handling (URL extraction, number formatting corrections) to improve user experience in search scenarios. Overall impact: higher installation success rates, fewer runtime edge cases, more predictable cross‑platform builds, and improved developer productivity through clearer build pipelines and refactoring efforts.
