Updates
Once a day, a little after it starts, Pragma Chess asks GitHub for the number of its latest version, and nothing else: no data about you or your computer is sent. When a newer one is out, the status bar says so for a moment and the Help menu offers Download Pragma Chess …, which opens its download page. Help ▸ Check for Updates… asks at once; Help ▸ Check for Updates at Startup turns the daily question off.
