Rails 5.1 testing changed attributes Deprecation warning

I just upgraded my 5.0.1 app to 5.1 and I get a huge amount of warnings when I run rspec tests.

DEPRECATION WARNING: ActiveSupport.halt_callback_chains_on_return_false= is deprecated and will be removed in Rails 5.2. (called from <top (required)> at /home/doomy/Documents/rsm/config/initializers/new_framework_defaults.rb:23)
...DEPRECATION WARNING: The behavior of `changed_attributes` inside of after callbacks will be changing in the next version of Rails. The new return value will reflect the behavior of calling the method after `save` returned (e.g. the opposite of what it returns now). To maintain the current behavior, use `saved_changes.transform_values(&:first)` instead. (called from block (3 levels) in <top (required)> at /home/doomy/Documents/rsm/spec/controllers/products_spec.rb:48)

This continues for every test I have and ends up taking significantly longer as it records so many things to the console.

I am rather confused as to what I should be changing as the offending code does not look out of the ordinary.

Here products_spec.rb around line 48

describe "GET show" do

before(:each) do
  @product = create(:product, user: create(:product_admin))
end

context "anonymously" do
  it "renders" do
    get :show, params: { id: @product.id }
    expect(response).to render_template("show")
  end
end

context "as regular user" do
  it "renders" do
    get :show, params: { id: @product.id }
    login(create(:user))
    expect(response).to render_template("show")
  end
end
...

      

        
        
        
      

    

I am guessing it should do something with the before filter, but I can't figure out what. Searching for the warning returns nothing useful.

Thank.
