Rails 3.2.3 was released!

Rails 3.2.3 has been released!!!.


This release changes the default value of
config.active_record.whitelist_attributes to true. This change only
affects newly generated applications so it should not cause any
backwards compatibility issues for users who are upgrading but it may
affect some tutorials and introductory material. For more information
see the mass assignment section of the ruby on rails security

Rails 3.2.3 also introduces a new option that allows you to control
the behavior of remote forms when it comes to authenticity_token
generation. If you want to fragment cache your forms, authenticity
token will also get cached, which isn’t acceptable. However, if you
only use such forms with ajax, you can disable token generation,
because it will be fetched from meta tag. Starting with 3.2.3, you
have an option to stop generating authenticity_token in remote forms
(ie. :remote => true is passed as an option), by setting
config.action_view.embed_authenticity_token_in_remote_forms = false.
Please note that this will break sending those forms with javascript
disabled. If you choose to not generate the token in remote forms by
default, you can still explicitly pass :authenticity_token => true
when generating the form to bypass this setting.
The option defaults to true, which means that existing apps are
NOT affected.

We’ve also adjusted the dependencies on rack-cache and mail to address
the recent security vulnerabilities with those libraries. If you are
running a vulnerable version of mail or rack-cache you should update
both gems to a safe version. There were also some regressions in the
render method that were fixed in this version.

CHANGES since 3.2.2

Action Mailer

  • Upgrade mail version to 2.4.3 ML

Action Pack

  • Fix #5632, render :inline set the proper rendered format.
    Santiago Pastorino

  • Fix textarea rendering when using plugins like HAML. Such plugins
    encode the first newline character in the content. This issue was
    introduced in https://github.com/rails/rails/pull/5191 James Coleman

  • Do not include the authenticity token in forms where remote: true
    as ajax forms use the meta-tag value DHH

  • Turn off verbose mode of rack-cache, we still have X-Rack-Cache to
    check that info. Closes #5245. Santiago Pastorino

  • Fix #5238, rendered_format is not set when template is not
    rendered. Piotr Sarnacki

  • Upgrade rack-cache to 1.2. Jos Valim

  • ActionController::SessionManagement is deprecated. Santiago

  • Since the router holds references to many parts of the system like
    engines, controllers and the application itself, inspecting the route
    set can actually be really slow, therefore we default alias inspect to
    to_s. Jos Valim

  • Add a new line after the textarea opening tag. Closes #393

  • Always pass a respond block from to responder. We should let the
    responder to decide what to do with the given overridden response
    block, and not short circuit it. sikachu

  • Fixes layout rendering regression from 3.2.2. Jos Valim

Active Model

  • No changes

Active Record

  • Added find_or_create_by_{attribute}! dynamic method. Andrew White

  • Whitelist all attribute assignment by default. Change the default
    for newly generated applications to whitelist all attribute
    assignment. Also update the generated model classes so users are
    reminded of the importance of attr_accessible. NZKoz

  • Update ActiveRecord::AttributeMethods#attribute_present? to return
    false for empty strings. Jacobkg

  • Fix associations when using per class databases. larskanis

  • Revert setting NOT NULL constraints in add_timestamps fxn
