#4457 [Santiago Pastorino, Marc-Andr\xc3\xa9 Lafortune]
* JSON supports a custom root option: to_json(:root => 'custom') #4515

you're destroying doesn't match lock_version in the database, a
StaleObjectError is raised. #1966 [Curtis Hawthorne]
* To prefix the table names of all models in a module, define
self.table_name_pr efix on the module. #4032 [Andrew White]

has_many. Optimization to re duce database queries. #3533 [Murray
Steele]

class method. #1211 [Mike Breen, Gabe da Silveira]
vulnerability in ruby-actionpack.
Major changes:
- Improved compatibility with Ruby 1.9
- RailsXss plugin availability
- Fixes for the Nokogiri backend for XmlMini
Changes since 2.1.1:
* Allow metal to live in plugins #2045 [Matthew Rudy]
* Added metal [Josh Peek]
* Remove script/performance/request in favour of the performance
integration tests. [Pratik Naik]
* Add a rake task to apply a template to an existing application :
rake rails:template LOCATION=~/template.rb [Pratik Naik]

automatically loaded (and reloaded when they change in dev mode)
[David Heinemeier Hansson]
* Added app/[models|controllers|helpers] to the load path for plugins
that has an app directory (go engines ;)) [David Heinemeier Hansson]
* Add config.preload_frameworks to load all frameworks at
startup. Default to false so Rails autoloads itself as it's
used. Turn this on for Passenger and JRuby. Also turned on by
config.threadsafe! [Jeremy Kemper]
* Add a rake task to generate dispatchers : rake
rails:generate_dispatchers [Pratik Naik]

application.rb to application_controller.rb -- included in rake
rails:update so upgrading to 2.3 will automatically trigger it #1439
[kastner]
* Added Rails.backtrace_cleaner as an accessor for the
Rails::BacktraceCleaner instance used by the framework to cut down
on backtrace noise and config/initializers/backtrace_silencers.rb to
add your own (or turn them all off) [David Heinemeier Hansson]

application_controller.rb and removed all the special casing that
was in place to support the former. You must do this rename in your

ActiveSupport::TestCase, also introduced a helper script to reduce
the needed require statements #1137 [Mathias Meyer]

standard plugin init path (init.rb) [Jacek Becela]

migrations with numeric prefix instead of UTC
timestamp. #446.
* Fixed that create database statements would always include "DEFAULT
NULL" [#334]
* change_column_default preserves the not-null constraint. #617
* Add :tokenizer option to validates_length_of to specify how to split
up the attribute string. #507. Example :
# Ensure essay contains at least 100 words.
validates_length_of :essay, :minimum => 100, :too_short => "Your
essay must be at least %d words."), :tokenizer => lambda {|str|
str.scan(/\w+/) }

* Depend on Action Pack 1.4.4
* Fix #count on a has_many :through association so that it recognizes the
:uniq option. Closes#8801 [lifofifo]
* Don't clobber includes passed to has_many.count [danger]

* Changing the :default Date format doesn't break date quoting. #6312
* Allow nil serialized attributes with a set class constraint. #7293

[dcmanges] Student.find(:all, :conditions => { :grade => 9..12 })
* Don't create instance writer methods for class attributes. [Rick]

bindings can do some translation for when sqlite3 breaks incompatibly
between point releases. [Jamis Buck]

* Consistently use LOWER() for uniqueness validations (rather than mixing with
UPPER()) so the database can always use a functional index on the lowercased
column. #6495 [Si]

inserted id. #6778 [Jonathan Viney, timc]

[Anthony Eden]
* SQLServer: quote table name in indexes query. #2928 [keithm@infused.org]
Active Record connects business objects and database tables to create
a persistable domain model where logic and data is presented in one
wrapping. It is an implementation of the object-relational mapping
(ORM) pattern by the same name as described by Martin Fowler:
"An object that wraps a row in a database table or view, encapsulates
the database access, and adds domain logic on that data."
Active Records main contribution to the pattern is to relieve the
original of two stunting problems: lack of associations and
inheritance. By adding a simple domain language-like set of macros to
describe the former and integrating the Single Table Inheritance
pattern for the latter, Active Record narrows the gap of functionality
between the data mapper and active record approach.
