If you have Photoshop on your system then go and update it NOW.

Don’t just think “I’ll do it later…..” because I know a lot of folk for whom later never comes!

And remember, if you have a Creative Cloud subscription then Lightroom, Photoshop and CameraRaw all need to up to date and in synch with each other all the time in order for the Lightroom>Photoshop>Lightroom workflow to function correctly.
