Kubuntu Developers have finally announced the release of second beta for 14.10 aka Utopic Unicorn. The beta shows the progress Kubuntu team has made towards the final release scheduled for October.
The beta comes with stable Plasma 4 and a preview of Plasma 5 which is still work in progress and misses some core features of Plasma. These features will be added in the future releases as and when they are ready. While Plasma 5 is not recommended for use on production systems, you can still use it to get work done and help developers in finding and fixing bugs – that’s the only ‘optional’ price a free software user has to pay.
