v0.2.15

Windows: TRXController-Setup-<version>.exe. Unsigned, so SmartScreen will warn on first run:
choose "More info" then "Run anyway". Installs per user under %LOCALAPPDATA%\Programs\TRXController;
log, settings and imported data live in %APPDATA%\TRXController.
TRXController-<version>-win-x64.zip is the same app with no installer: unzip it anywhere and run
TRXController.exe. Use it if the installer is blocked on your machine.

macOS (Apple silicon): TRXController-<version>-mac-arm64.dmg. Unsigned and not notarised, so on
first launch right-click the app and choose Open (or run xattr -dr com.apple.quarantine /Applications/TRXController.app).
Data lives in ~/Library/Application Support/TRXController.
