The location of the config folder has changed. OctoPrint will try to migrate the configuration from its old location (~/.printerwebui, ...) to its new one (~/.octoprint, ...). For this to work the following conditions must be met: 1) the old config folder exists and is a directory 2) the new config folder does not exist at all. The migration functionality will be in the future.
Allows reading and writing default serial port and baudrate (this also is available via the web interface) and setting the host and port on which the server should listen. Might allow persisting more options in the future.
The configuration file is stored in ~/.printerwebui/config.ini under Linux, in %APPDATA%/PrinterWebUI/config.ini under Windows and should be stored in ~/Library/Application Support/config.ini under MacOS X
