The beta of the Cosmic Cuttlefish (to become 18.10) has now been released, and is available for download at http://cdimage.ubuntu.com/kubuntu/releases/18.10/beta/
This milestone features images for Kubuntu and other Ubuntu flavours.
Pre-releases of the Cosmic Cuttlefish are not encouraged for:
* Anyone needing a stable system
* Anyone who is not comfortable running into occasional, even frequent breakage.
They are, however, recommended for:
* Ubuntu flavour developers
* Those who want to help in testing, reporting, and fixing bugs as we work towards getting this release ready.
* the Beta includes some software updates that are ready for broader testing. However, it is an early set of images, so you should expect some bugs.
