Q: Should I Update to Remote Desktop 3.8.2. v1.1 - I don't have the system requirements it asks for!

My Current System:
iMac (21.5-inch Mid 2010), Mac OS X (10.8.5) - Mountain Lion

HELP!!
I recently received notice of the Remote Desktop Update 3.8.2. v1.1.
There are certain requirements listed before updating.

The information and system requirements for this update are at this link:
About Remote Desktop Admin 3.8 - Apple Support

They say Remote Desktop 3.8 requires the following: OS X v10.9 or later.
I currently have Mountain Lion - v10.8.5 and wonder why this update even showed up.
I don't have need for it ... I've never installed Apple Remote Desktop.

Do I update, or ignore it?
