Sansa Clip+ Firmware Update 01.02.18

I wanted to check to see if my Clip+ needed updating, so I first downloaded the Sansa Updater.  It didn’t say there was new firmware available, just the manual.  However, the website said the latest version was 1.02.18, whereas I have 1.02.16A.  So, I went to the manual firmware installation page, and read through the directions.  It said at the end to go into the system information on the player and check that the firmware version is now 1.02.16.  I’m just wondering; is this a typo or do I actually have the latest version?  I just don’t want to accidentally brick my player or something.
