Rails 3.2:

• https://github.com/rails/rails/commit/5b9a506ef6b72c93901e94a0f738c1991f8d5852
• config.assets.logger = false
• rails/rails#4569

frontend-helpers

Omniauth and Rack 1.4 version number (Fixed in Rack 1.4.1)

• undefined method `include?' for nil:NilClass
• rack/rack#322
• using gem "rack", git: "https://github.com/rack/rack.git", ref: "e20baec005238f9876281c0d083fe5a4e01aa034"

Unfortunately config.assets.logger = false silents only Sprockets log but not all the Started GET "/assets/whatever.js?body=1" stuff. You still need initializer. See rails/rails#4569
