## Rails 3.2.1 (January 26, 2012) ##
* Documentation fixes.
* Migration generation understands decimal{1.2} and decimal{1-2}, in
addition to decimal{1,2}. *José Valim*
## Rails 3.2.0 (January 20, 2012) ##
* Rails 2.3-style plugins in vendor/plugins are deprecated and will be removed in Rails 4.0. Move them out of vendor/plugins and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb. *Santiago Pastorino*
* Guides are available as a single .mobi for the Kindle and free Kindle readers apps. *Michael Pearson & Xavier Noria*
* Allow scaffold/model/migration generators to accept a "index" and "uniq" modifiers, as in: "tracking_id:integer:uniq" in order to generate (unique) indexes. Some types also accept custom options, for instance, you can specify the precision and scale for decimals as "price:decimal{7,2}". *Dmitrii Samoilov*
* Added `config.exceptions_app` to set the exceptions application invoked by the ShowException middleware when an exception happens. Defaults to `ActionDispatch::PublicExceptions.new(Rails.public_path)`. *José Valim*
* Speed up development by only reloading classes if dependencies files changed. This can be turned off by setting `config.reload_classes_only_on_change` to false. *José Valim*
* New applications get a flag `config.active_record.auto_explain_threshold_in_seconds` in the environments configuration files. With a value of 0.5 in development.rb, and commented out in production.rb. No mention in test.rb. *fxn*
* Add DebugExceptions middleware which contains features extracted from ShowExceptions middleware *José Valim*
* Display mounted engine's routes in `rake routes` *Piotr Sarnacki*
* Allow to change the loading order of railties with `config.railties_order=` *Piotr Sarnacki*
Example:
config.railties_order = [Blog::Engine, :main_app, :all]
* Scaffold returns 204 No Content for API requests without content. This makes scaffold work with jQuery out of the box *José Valim*
* Update Rails::Rack::Logger middleware to apply any tags set in config.log_tags to the newly ActiveSupport::TaggedLogging Rails.logger. This makes it easy to tag log lines with debug information like subdomain and request id -- both very helpful in debugging multi-user production applications *DHH*
* Default options to `rails new` can be set in ~/.railsrc *Guillermo Iguaran*
* Add destroy alias to Rails engines *Guillermo Iguaran*
* Add destroy alias for Rails command line. This allows the following: `rails d model post` *Andrey Ognevsky*
* Attributes on scaffold and model generators default to string. This allows the following: "rails g scaffold Post title body:text author" *José Valim*
* Remove old plugin generator (`rails generate plugin`) in favor of `rails plugin new` command *Guillermo Iguaran*
* Remove old 'config.paths.app.controller' API in favor of 'config.paths["app/controller"]' API *Guillermo Iguaran*
