Rails 3.2.3 has been released!!!.
### IMPORTANT
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 guide][1]
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.

*Action Mailer*
* Upgrade mail version to 2.4.3 *ML*
*Action Pack*
* Fix #5632, render :inline set the proper rendered format. *Santiago Pastorino*

* 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. *José Valim*
* ActionController::SessionManagement is deprecated. *Santiago Pastorino*
* 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. *José Valim*
* Add a new line after the textarea opening tag. Closes #393 *rafaelfranca*
