Sydney Pro theme update question

for a about a year i have had sydney pro 2. there was some problem with its registration and i did not get any updates. we resolved the issue by re purchasing the license at 100% discount. i installed this and deleted the original. looks like the code was updated sometime in July 2018. is this correct? my main question is when updates get pushed out to registered owners of the theme will they replace all the theme code, replace only the changed files, or update lines of code within files? thanks

Hello,

Sydney Pro theme was updated several months ago. Updates replace all the theme code. Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
