* No changes


* stylesheet_link_tag('/stylesheets/application') and similar helpers doesn't
throw Sprockets::FileOutsidePaths exception anymore [Santiago Pastorino]

* Ensure default_asset_host_protocol is respected, closes #2980. [José Valim]

  Changing rake db:schema:dump to run :environment as well as :load_config,
  as running :load_config alone will lead to the dumper being run without
  including extensions such as those included in foreigner and

  This reverses a change made here:

  I'm assuming here that :load_config needs to be invoked
  separately from :environment, as it is elsewhere in the
  file for db operations, if not the alternative is to go
  back to "task :dump => :environment do".

  [Ben Woosley]

* Update to rack-cache 1.1.

  Versions prior to 1.1 delete the If-Modified-Since and If-Not-Modified
  headers when config.action_controller.perform_caching is true. This has two
    * unexpected inconsistent behaviour between development &
      production environments
    * breaks applications that use of these headers

  [Brendan Ribera]

* Ensure that enhancements to assets:precompile task are only run once
[Sam Pohlenz]

* TestCase should respect the view_assigns API instead of pulling variables on
its own. [José Valim]

* javascript_path and stylesheet_path now refer to /assets if asset pipelining
is on. [Santiago Pastorino]

* button_to support form option. Now you're able to pass for example
'data-type' => 'json'. [ihower]

* image_path and image_tag should use /assets if asset pipelining is turned
on. Closes #3126 [Santiago Pastorino and christos]

* Avoid use of existing precompiled assets during rake assets:precompile run.
Closes #3119 [Guillermo Iguaran]

* Copy assets to nondigested filenames too [Santiago Pastorino]

* Give precedence to `config.digest = false` over the existence of
manifest.yml asset digests [christos]

* escape options for the stylesheet_link_tag method [Alexey Vakhov]

* Re-launch assets:precompile task using (Rake.)ruby instead of Kernel.exec so
it works on Windows [cablegram]

* env var passed to process shouldn't be modified in process method. [Santiago

* `rake assets:precompile` loads the application but does not initialize

  To the app developer, this means configuration add in
  config/initializers/* will not be executed.

  Plugins developers need to special case their initializers that are
  meant to be run in the assets group by adding :group => :assets. [José Valim]

* Sprockets uses config.assets.prefix for asset_path [asee]

* FileStore key_file_path properly limit filenames to 255 characters.

* Fix Hash#to_query edge case with html_safe strings. [brainopia]

* Allow asset tag helper methods to accept :digest => false option in
order to completely avoid the digest generation.
Useful for linking assets from static html files or from emails when the user
could probably look at an older html email with an older asset.
[Santiago Pastorino]

* Don't mount Sprockets server at config.assets.prefix if
config.assets.compile is false. [Mark J. Titorenko]

* Set relative url root in assets when controller isn't available for
Sprockets (eg. Sass files using asset_path). Fixes #2435 [Guillermo

* Fix basic auth credential generation to not make newlines. GH #2882

* Fixed the behavior of asset pipeline when config.assets.digest and
config.assets.compile are false and requested asset isn't precompiled.
  Before the requested asset were compiled anyway ignoring that the
config.assets.compile flag is false. [Guillermo Iguaran]

* CookieJar is now Enumerable. Fixes #2795

* Fixed AssetNotPrecompiled error raised when rake assets:precompile
is compiling certain .erb files. See GH #2763 #2765 #2805 [Guillermo

* Manifest is correctly placed in assets path when default assets
prefix is changed. Fixes #2776 [Guillermo Iguaran]

* Fixed stylesheet_link_tag and javascript_include_tag to respect
additional options passed by the users when debug is on. [Guillermo

* Fix ActiveRecord#exists? when passsed a nil value

* Fix assert_select_email to work on multipart and non-multipart
emails as the method stopped working correctly in Rails 3.x due to
changes in the new mail gem.


* Remove hard dependency on bcrypt-ruby to avoid make ActiveModel
dependent on a binary library.
  You must add the gem explicitly to your Gemfile if you want use

  gem 'bcrypt-ruby', '~> 3.0.0'

  See GH #2687. [Guillermo Iguaran]


* Add deprecation for the preload_associations method. Fixes #3022.

  [Jon Leighton]

set_primary_key. GH #2807.

  [Jon Leighton]

* Fix using select() with a habtm association, e.g.
Person.friends.select(:name). GH #3030 and

  [Hendy Tanata]

  Fixes #3020.

  [Jon Leighton]

* LRU cache in mysql and sqlite are now per-process caches.

  * lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache
    keys are per process id.
  * lib/active_record/connection_adapters/sqlite_adapter.rb: ditto

* Database adapters use a statement pool for limiting the number of open
  prepared statments on the database. The limit defaults to 1000, but can
  be adjusted in your database config by changing 'statement_limit'.

* Fix clash between using 'preload', 'joins' or 'eager_load' in a
default scope and including the
  default scoped model in a nested through association. (GH #2834.)
[Jon Leighton]

* Ensure we are not comparing a string with a symbol in
  Fixes GH #2755, where a counter cache could be decremented twice as
far as it was supposed to be.

  [Jon Leighton]

  GH #2828. [Georg Friedrich]

* Fixed find_in_batches method to not include order from
default_scope. See GH #2832 [Arun Agrawal]

each time [Tim Lucas]

Can you provide a fix for it?.
