Hardware Enablement Stack notice?

[Jim Byrnes]

I've been running LTS releases since 10.04 and this is the first one of 
these notices I have received.  At first I was confused about it but I 
read the wiki and some other links and I have a better understanding now.

I am running VirtualBox 5.0.26 which Synaptic shows in Local/Contrib.
How will running this update effect my VBox install?

Regards,  Jim
