Updates to the Jolicloud OS, based on Ubuntu 10.04, and the Jolicloud desktop environment, available for Ubuntu 12.04 and up through a PPA, will be discontinued in December of this year.
Jolicloud Desktop Environment for Ubuntu has been updated with some modest changes - including improved theming, non-free codecs and more.
The 'Jolicloud Desktop Environment' puts a HTML5 launcher with shortcuts to popular websites and services front and center, in place of the traditional desktop.
Jolidrive, a dashboard for managing various online accounts including Dropbox and Google Drive, has added support for Ubuntu One.
