What's new in 1.2.4? - Improved events reporting, translation - Fixed a bug when exporting to ADIF and added frequency to the ADIF file - Fixed bug when going to background What's new in 1.2.3? - Improved performance and reduced battery consumption What's new in 1.2.0? *** New Features - Contacts Management Improved handling and integration of contacts within the application. - Country Display in Logbook The Logbook now display the country associated with each callsign for easier identification. - Callsign Location Detection The app can now infer and show approximate location based on callsign prefix. *** Improvements - Map Controls Added options to enable or disable specific map elements for better customization. - AutoCQ Smart Behavior AutoCQ will not call for CQ when de DX is already in the list of QSO - Dynamic Log File Naming Log files now include timestamps (e.g., `FT_HAM_Log_YYYYMMDD_HHMMSS`) to avoid overwriting and make log organization easier. - Log Export Enhancements - Incremental export support. - Ability to export only new logs. - Option to select a specific date range instead of exporting the full history. *** Bug Fixes - Several general bugfixes to improve usability and performance - Auto TX and Logging (Interleaved QSO Issue) Fixed an issue where interleaved QSOs could produce incorrect “invalid” entries in the Sent and Received log fields when reports were not received in a simple 1-to-1 exchange sequence. - Callsign Switching Logic Fixed a bug where the application could continue transmitting to the previous station instead of switching to the new target callsign after receiving a signal report.
