【Version 4.4.9.0】 Settings Page Redesign: Removed native setting groups and switched to a flat, category-based layout. This resolves a saving bug associated with grouped settings, with a slight trade-off in visual organization to ensure reliability. Dual Data Fields: Added a new dual-field display option for the third row, allowing two additional metrics to be shown. Fueling information can automatically take priority when an upcoming reminder is near. Improved Long Fueling Messages: Long fueling instructions are now displayed together on the same screen instead of cycling between messages. Enhanced Daily Hydration Reminders: Reminder intervals are now configured in meters, with a default of 5,000 meters. Intervals below 1,000 meters are disabled. The reminder toggle is also available in the Basic Edition. Expanded Device Compatibility: Added support for more Garmin models. Improved Support for Older 128KB Devices: Retained dual data fields, layered display of long fueling messages, and superscript hour indicators, while optimizing memory usage, plan saving, and license verification. 【Version 4.4.8.0】 Refined Number Display: Adjusted numeric typography to be slightly smaller but clearer, without excessive horizontal stretching. Dynamic Data Icons: Top and bottom icons can now automatically change based on the selected data fields. Custom icon selection is also supported. Improved Fueling Information Display: Distance/countdown information and fueling instructions are prioritized for simultaneous display. Automatic cycling is used only when the content exceeds the available width. 【Version 4.4.7.1】 Fixed a layout issue on non-MIP displays when a data label contained four characters. 【Version 4.4.7.0】 Custom Fueling Plans: Added three customizable fueling plans for the Advanced Edition. Each plan supports independent pre-race, distance-based, and time-based fueling settings. Plan 1 retains the original fueling configuration. Pace Trend Chart: Added a pace trend chart to the middle display area. Both heart rate and pace trends can be configured to show the last 3, 6, or 9 minutes. Race Finish Prediction: Added estimated finish time, time difference from the target, and required pace for the remaining distance. These metrics can be added to the data display layout as needed. Unified Fueling Mode: Combined activity scenario selection and fueling plan selection into a single "Fueling Mode" setting, allowing users to switch between daily hydration reminders, built-in race plans, and custom fueling plans. Expanded Distance-Based Fueling: Increased the maximum number of distance-based fueling entries to 48. Default pre-race fueling reminders are no longer displayed when the pre-race fueling list is empty.
