Testing has begun for the Final Beta (Beta 2) of Lubuntu 14.10 Utopic Unicorn. Head on over to the ISO tracker to download images, view testcases, and report results. If you're new to testing, anyone can join and they don't have to be Linux Jedis or anything. You can find all the information you need to get started here.
Please note that we especially need testers for PPC chips and Intel Macs. We have a special section discussing it here. In particular, if you have an Intel Mac, I have a few questions for you that might help us trim down the workload of the testing team.
Also, if you have a PPC chip, we're about the only distro actively supporting this architecture. However, we are community supported, so without formal testing, the arch will lose more support. So please, join in testing!
