Hi!
Do you plan to release/port the features from “Pro” into the open core version at any stage? Say, with a few weeks/months delay?
It’s not planned.
Will there be any new development done on the free version or will it be pure maintenance with no new features added?
It’s hard to know today what will be added into one version or the other. I will privilege Polylang Pro. But I will still add new features to the free version.
For your information, I started developing Polylang 1.8 and Polylang Pro at the same time. So if you look at the changelog for Polylang 1.8.x and Polylang 1.9, you will get an idea of what I decided to add to one version or the other.
