Jan 1, 2026January 2026 performance summary for cgeo/cgeo: Key features delivered: - Geocaching Coordinate Validation Enhancement: adds a second geochecker URL to improve validation coverage and reliability for users who rely on multiple endpoints. - HTML Rendering Improvement with Jsoup: integrates Jsoup to clean problematic HTML elements, addressing zero-width spans and rendering inconsistencies. - Default Theme Follows System Settings: updates default theme for new installations to follow system settings, removing the legacy skin preference for a streamlined experience. - UI/UX Enhancements: Action Bar and Snackbar: introduces a configurable colored action bar that adapts to light/dark themes and improves snackbar behavior for cache deletions; includes related UI tweaks and reduced animations. - Coordinate Format Persistence Across Fragments: ensures the user’s selected coordinate format persists across fragment recreations; adds storage/retrieval and input validation for a smoother experience. - Geocaching Logs Ownership Tagging: marks own/owner logs for better visibility of personal and owner logs. Major bugs fixed: - Cache Popup Stability Bug Fix: prevents a UI crash by guarding against a null background drawable before mutation and tint operations (fix #17750). Overall impact and accomplishments: - Improved reliability, stability, and UX across the app with broader validation coverage, persistent user preferences, and clearer log ownership indicators. These changes reduce support burden, boost user confidence, and streamline onboarding for new installations. Technologies/skills demonstrated: - Jsoup HTML cleaning and parsing for robust rendering. - Android theming and system settings integration (default theme based on system settings). - UI/UX design: configurable action bars, theming across light/dark modes, and enhanced snackbars. - Fragment lifecycle handling and state persistence. - Logging/OKAPI integration for ownership tagging and visibility. - Documentation and small-code hygiene improvements.

Apr 1, 2025April 2025 (2025-04) focused on improving offline cache management, UI consistency, and translation/date formatting UX, while addressing a critical data ordering bug. Key deliverables include offline caches management and list UX enhancements that optimize performance, clarify menu labels, handle deletion of past events and offline logs, and allow removing caches from other lists to avoid duplicates. A bug fix corrected distance sorting by moving sort logic to CacheComparator and removing an unused MultiComparator, ensuring correct distance ordering. Translation Language Settings and UX Enhancements introduced an automatic language option, preserved the translation source language across restarts, reduced unnecessary re-translation, improved cancellation UX, and safe initialization of language/date preferences. Date/Format UI Enhancements added the ability to display the selected date-format in preferences and refined the Sec-format layout for readability. These changes improve reliability, reduce user friction, and drive business value through faster offline workflows, more accurate data presentation, and smoother localization.
