  • Allow asset tag helper methods to accept :digest => false option in

  • 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

      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
    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 L.]

    Fixes GH #2755, where a counter cache could be decremented twice as
    far as it was supposed to be.

  • Add jquery-rails to Gemfile of plugins, test/dummy app needs it.
    Closes #3091. [Santiago Pastorino]

  • 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.
