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 guide
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.
