An OFFICIAL Assembly release is now available through the Assembly Downloader which you can find here or via https://github.com/XboxChaos/Assembly/releases/tag/downloader.
Select the "dev" option from the downloader and you are good to go! Ignore the update prompt you'll get and instead go to Tools>Settings and set yourself to the Experimental branch to receive future updates.
Full MCC support added! (3 comments)
