If I go to appium.io I find a download link at github.com/appium/appium-desktop for stable 1.13.0 at https://github.com/appium/appium-desktop/releases/
There also exists a github.com/appium/appium repository at https://github.com/appium/appium/releases with current stable 1.14.1
On my Mac, I am running Version 1.14.0 (1.14.0.20190705.4) according to the Appium→About Appium menu, the main window shows the button Start Server v1.14.0, and starting a server shows Welcome to Appium v1.14.0 in the log, but selecting Check For Updates in the menu tells me that Appium Desktop v1.13.0 is available from May 5, which includes an update to Appium version 1.13.0.
How do I resolve these differing version numbers and the apparent downgrade?
