The opencart template format is Twig. Are there any serious differences in the development process of version 3 from the second?

Question

Twig

Good day. About a year and a half ago, I made a site on opencart 2 version. I did, according to this approach, as advised by more experienced guys - I was engaged, roughly speaking, in styling the default template. Created a new folder with the site in templates. I took templates from the default (which were still .tpl). I put it in a new folder, and changed them already there, without affecting the default. So I made this site, then for about a year I did not work with the system. Now we need to create an online store on opencart. And here I saw version 3 with new twig templates. I’ll write version 3 right away, I haven’t watched or read about it yet)) I’ll definitely get to know each other. We just need to get the site up and running. I think to do on a new one or there will be problems (I will be stupid) or use the second one with which I am familiar.

Answer 1

If you need to do it quickly, calmly do it on the second.
