Gem conflict with spree version 4.0

[timuckun]

Bundler could not find compatible versions for gem "spree_backend":
  In snapshot (Gemfile.lock):
    spree_backend (= 4.0.0)

  In Gemfile:
    spree (~> 4.0) was resolved to 4.0.0, which depends on
      spree_backend (= 4.0.0)

    spree_multi_currency was resolved to 3.3.0.rc1, which depends on
      spree_backend (>= 3.1.0, < 4.0)

    spree_multi_vendor was resolved to 1.4.0, which depends on
      spree_backend (>= 3.2.0, < 5.0)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

Was this issue fixed??

I don't know. There are many forks of this gem, this is the one I am using
