Lubuntu Artful Aardvark Alpha 1 (soon to be 17.10) has been released! Also in this release (in addition to the usual LXDE ISO) is an experimental image with LXQt instead of LXDE.
For the LXDE edition, we have a couple papercuts listed in the release notes, so please take a look there.

We recommend that if you install Lubuntu Artful Aardvark Alpha 1, that you download the LXDE edition rather than the experimental LXQt ISO. The LXQt ISO will most likely break your system.
If you would like to read the release notes for Lubuntu Next (the experimental LXQt edition of Lubuntu), you can find them here. The release notes lists all of the known issues for the images.
