I have the same link...
Just i wanted to know whether above mentioned versions are Major or Minor?
Any change n the first two digits would be major.
Ok.. if i consider CC 2017 is major version and CC 2017.1 is minor .. what does 18.0 signify?
From CC2015 (17) to CC2017 (18).
Refer the full history of Photoshop showing the relationship between major version numbers and CC numbers.
CC 2014 (15.x)
CC 2015 (16.x)
CC 2015.5 (17.x)
CC 2017 (18.x)
