Nintendo Switch emulator Ryujinx will be changing its release system, due to a problem with its current set up. AppVeyor has previously been hosting Ryujinx and has allowed for users to automatically update their builds whenever a new release is out. However, you won't be able to do that anymore, until you manually download the latest release, 1.1.3, which will now be hosted via GitHub Releases. Some may get a popup as well, regarding an update error, which is also solved by going to the Ryujinx site and grabbing the 1.1.3 build.
As @appveyor took our project down for unknown reasons, we were forced to switch to a new release system.— Ryujinx (@RyujinxEmu) January 22, 2022
