You can use the menu entry "Help/Software updates/Available Software" to update from version 1.0.0 to 1.1.0. If you have a problem during installation, uninstall version 1.0.0 first. Note that you must set up your compiler settings again since the data structure of the preferences was changed to support multiple compilers at once.
