Latest 0.4.8·September 20, 2026

Release Notes
  • Fixes a bug that could stop the app starting at all: a single running copy could mistake itself for a second one and exit silently, with no window and no tray icon.
  • An update that fails now says so. Previously a failed update was invisible, so an install could sit behind for weeks with nobody aware, and a failed attempt could retry in a loop.

Installer type: wix
