Redefinition of PaperTrail::Version stopped working in v12/v14 with Rails 6.1 using Zeitwerk about paper_trail HOT 3 CLOSED

Im updating a project to rails 6.1 and im having the same issue using zeitwerk 2.6.7, i've updated paper_trail to 12.1 but having a model like

module PaperTrail
  class Version < ActiveRecord::Base
     include PaperTrail::VersionConcern
  end
end

class PostVersion < PaperTrail::Version
  self.table_name = :post_versions
  self.sequence_name = :post_versions_id_seq
end

im getting an error loading that model:
NameError: uninitialized constant PaperTrail::VersionConcern

I updated the gem because in the compatibility table is mentioned that version 11 requires rails >= 5.2, < 6.1, not rails <= 6.1
For now I must use version 11.1, and solve the problem with the models that include the limit parameter, adding a migration to add the item_subtype column.

Why would you do that and not just use PaperTrail::Version?
