I am developing a new extension, could it be possible to create a contrib repository for it?
This extension covers the needs for managing and publishing documentation (a collection of pages, hence the book name) that is versioned (with version inheritance as well as unversioned content), described by a status, that can be conditioned by variants, in multiple languages and using libraries of keywords/rich content dynamically filled in.
It aims at providing similar features as Scroll Versions extension for Confluence.
I suggest the name book-versions for it.
