Not compatible with spree 3.7.0 or upgraded versions

[vinaymehta]

HI Team,

I tried using this gem in my latest rails application having following gems specifications. But its not letting us to be used.

ruby '2.5.3'
gem 'rails', '~> 5.2.3'
gem 'spree', github: 'spree/spree'
gem 'spree_auth_devise', github: 'spree/spree_auth_devise'
gem 'spree_multi_tenant', github: 'stefansenk/spree_multi_tenant'

and it gives error like below

Bundler could not find compatible versions for gem "spree_core":
  In Gemfile:
    spree was resolved to 4.0.0.alpha, which depends on
      spree_core (= 4.0.0.alpha)

    spree_multi_tenant was resolved to 0.4.0, which depends on
      spree_core (~> 2.2.0)

Let me know if any other information you need. Please help me to setup this gem in my application. Thanks in advance
