Genuine popup?? "Product Update Available!"

Hi All,

Currently running 19.9.0.9 and for the first time I can remember I have got the (hopefully) attached  pop-up 

 

What is making me suspicious is:

  1. I've never seen this before
  2. It is not offering any info as to what the update is about - minor update/major version etc
  3. 1 min install?

Is it genuine, and if so what is the update (20.x perhaps, but why no info - I may not want it!)

 

Thanks very much
