When I click “Check for Update” in version 1.12.9, Atom reports there are no updates available. However, the website and blog report that version 1.13.0 exists. I found the SquirrelSetup.log file and saw that unhandled exceptions were being thrown every time I attempted to update, stemming from the update location returning a 404: Not Found. Is the update server down? Or perhaps I have the wrong address to look for updates?
Here is the relevant part of the trace.
