Date	Update
16/07/2026	Added a CW ranking WPM range filter after operator login, so CW scores can be viewed by listening-speed groups.
06/07/2026	Added regular slash-call practice across Typing, SSB and CW, with about 10% of generated calls using /P, /M or portable-style prefixes. Added practice prefixes such as EA6/, CT7/, M/, DL/, S5/, EA8/, CU2/, CT8/, KH2/, VP5/, PJ5/, PJ6/, PJ4/, PJ2/, PA/, ON/, F/, EA/ and EA9/. Improved accuracy display so sessions with small errors can show decimal values such as 99.5% instead of rounding to 100%. Adjusted the mobile ranking accuracy column so decimal percentages fit cleanly on smartphones.
05/07/2026	Added a CW setup preview so WPM, pitch and weight sliders play TEST while being adjusted. Improved the smartphone home layout, including tighter flag/support spacing and ranking table column widths. Kept the callsign and name fields side by side on smartphone screens. Shortened the Latest updates section for a cleaner mobile view.
30/06/2026	Added the new CW4EVER Trainer logo to the website and browser icon. Countries represented now use IP country when available, with callsign country as the fallback. Improved the country flag display so it shows only the number of operators per country. Fixed support links so PayPal, Revolut and Buy Me a Coffee open directly.
