V12 and the latest version. What to read to see the difference?

[Timur]

I am thinking about migration to the latest version from 12 version. How to know is it worth or not?

Hi Timur,

You can find more details here about the features of the latest version. Basically it depends of the customer requirements. However the only maintained version is 15.
