For those of you testing antiX-15-beta3 you will notice some debs coming down with an apt-get dist-upgrade.
Hopefully, they fix some of the issues mentioned in the feedback thread.

There is also a new kernel available 4.0.4 that should not have the raid issue of previous 4.0 kernels (though our 4.0 kernel might have been ok, but I don't have raid to check).

You have to install manually vis synaptic or apt-get.
