Rev 2.7 - Update or Upgrade?

[Garrett Hylltun]

Greetings,

What constitutes an update and an upgrade?

I'm a little confused now and finding myself getting a little upset  
here.  I thought an upgrade was like from version 1.x to 2.x and  
updates were like 1.1 through 1.9 etc.

I bought Rev 2.6.1 and now it's 2.7 and if I read correctly, they are  
calling it an upgrade which means I am not by my license to use it.   
Means I need to spend what? another $149 to get it?

Anyone clarify for me?

Thanks,
-Garrett
