This option is now unsupported in sprockets-rails.

Date.beginning_of_week thread local and beginning_of_week application config option added (default is Monday)

erb tag wasn't closed well

The new option allows any Ruby namespace to be registered and set
up for eager load. We are effectively exposing the structure existing
in Rails since v3.0 for all developers in order to make their applications
thread-safe and CoW friendly.

The flag was mainly used to add a Rack::Lock middleware to
the stack, but the only scenario the lock is desired is in
development.

If you are deploying on a not-threaded server, the Rack::Lock
does not provide any benefit since you don't have concurrent
accesses. On the other hand, if you are on a threaded server,
you don't want the lock, since it defeats the purpose of using
a threaded server.

If there is someone out there, running on a thread server
and does want a lock, it can be added to your environment
as easy as: `use Rack::Lock`

With a value of "nosniff", this prevents Internet Explorer from MIME-sniffing a response away from the declared content-type.

Add documentation for config.action_dispatch.default_headers to
Rails Configuring guide.

[ci skip]

Allows to easily set :from, :replay_to, etc. options in
config/application.rb using simple syntax:

  config.action_mailer.default_options = {from:"no-replay@example.org"}

This was not possible using #default method because

  config.action_mailer.default(from: "no-replay@example.org")

is interpreated as reader method and just returns nil.
It would not call ActionMailer::Base.default method. The only
way of calling this method from config/application.rb was to use
the direct syntax which looks ugly in my opinion:

  config.assets.enabled = false
  config.assets.version = '1.0'
  config.encoding = "utf-8"
  config.action_mailer.default_url_options= {
    host:"example.org",
    protocol:"https"
  }
  ActionMailer::Base.default(from: "no-replay@example.org")

The former is grammatically incorrect.

closes #3341

config.action_view.prefix_partial_path_with_controller_namespace

This allows you to choose to render @post using
/posts/_post.erb instead of /admin/posts/_post.erb
inside Admin::PostsController.

Changed default value for `config.action_view.embed_authenticity_token_in_remote_forms`
to `false`. This change breaks remote forms that need to work also without javascript,
so if you need such behavior, you can either set it to `true` or explicitly pass
`:authenticity_token => true` in form options

There is a regression introduced in 16ee611f, which breaks
remote forms that should also work without javascript. This commit
introduces config option that allows to configure this behavior
defaulting to the old behavior (ie. include authenticity token
in remote forms by default)
