Some weekend stable kernel updates
The 4.18.18, 4.14.80, 4.9.136, 4.4.163, and 3.18.125 stable kernel updates have all been released; each contains a relatively large set of important fixes.

The 3.18.x updates may be about to come to an end, since it is not clear that anybody is using them. "And from what I can see in the 'real world', no one is actually updating devices that rely on 3.18.y to the newer kernel releases. So I think I'm going to stop maintaining this tree soon unless someone speaks up and says 'I am using it!''
