What is hot in drupal now?

Question

Drupal

There is a task to make a module for Drupal. And, accordingly, the question is, how relevant are versions 6 and 7, or has everyone already switched to 8 and do it only on it?
What is used for ubercart online stores or is there something else?

Answer 1

See support.
As soon as official support is discontinued, the version is out of date.
I would no longer consider 100%
Well, in terms of laboriousness, look.
Since the latest version.
And then to do or not the penultimate one - according to the complexity of the work.

Answer 2

6 can be forgotten.
Development under 7 and 8 should differ radically.
I would choose 7 for mainstream.
If for one client, then there is still time until 8.

Answer 3

For more or less complex and large projects, I use version 7, for which there are most of the necessary modules.
If you want to experiment and the project is not too complicated - you can take the eight.
Online stores are written in Drupal Commerce.
