Dec 1, 2025

Month: 2025-12. The ConservationInternational/cplus-plugin team delivered a focused set of releases and reliability improvements that strengthen release readiness, cross‑platform support, and developer efficiency. Key features delivered include version bumps across QGIS plugin releases to reflect new plugin versions (config.json), PNG chart generation for reports on Linux/Unix with improved HTML rendering and a robust fallback when image generation fails, and a Qt6 compatibility refresh with updated constants, resources handling, event loop adjustments, and updated tests/mocks. In addition, usability enhancements were added to allow pathway UUIDs in the Decision Tree algorithm as a JSON array. Raster UI stability improvements addressed check state/selection logic and reverted widgets to a stable functional state. Major bugs fixed include enabling chart generation in reports (Fixes #805) and correcting UI stability regressions in the raster manager. Overall impact includes smoother, more reliable releases, improved cross‑platform usability, and higher confidence in automated tests and logs. Technologies demonstrated encompass Qt6 migration, JSON data handling, robust error logging, and end‑to‑end testing improvements.
