I fail to install openproject-auth_plugins on the ‘stable’ branch of OpenProject. If I install using the ‘stable’ branch of openproject-plugins and openproject-auth_plugins I get the following error:

Bundler could not find compatible versions for gem "openproject-plugins":
  In Gemfile:
    openproject-auth_plugins (>= 0) ruby depends on
      openproject-plugins (~> 1.0) ruby

    openproject-plugins (3.0.8)

which makes no sense to my limited knowledge of Ruby on Rails. openproject-auth_plugins needs openproject-plugins ~> 1.0, yet it has 3.0.8.

I hope someone can point me in the right direction here,
thanks in advance
