-*Rails 3.1.0 (unreleased)*
+*Rails 3.2.0 (unreleased)*
+
+* In development mode the db:drop task also drops the test database. For symmetry with
+  the db:create task. [Dmitriy Kiriyenko]
+
+* Added ActiveRecord::Base.store for declaring simple single-column key/value stores [DHH]
+
+    class User < ActiveRecord::Base
+      store :settings, accessors: [ :color, :homepage ]
+    end
+
+    u = User.new(color: 'black', homepage: '37signals.com')
+    u.color                          # Accessor stored attribute
+    u.settings[:country] = 'Denmark' # Any attribute, even if not specified with an accessor
+
+
+* MySQL: case-insensitive uniqueness validation avoids calling LOWER when
+  the column already uses a case-insensitive collation. Fixes #561.
+
+  [Joseph Palermo]
+
+* Transactional fixtures enlist all active database connections. You can test
+  models on different connections without disabling transactional fixtures.
+
+  [Jeremy Kemper]
+
+* Add first_or_create, first_or_create!, first_or_initialize methods to Active Record. This is a
+  better approach over the old find_or_create_by dynamic methods because it's clearer which
+  arguments are used to find the record and which are used to create it:
+
+    User.where(:first_name => "Scarlett").first_or_create!(:last_name => "Johansson")
+
+  [Andrés Mejía]
+
+* Fix nested attributes bug where _destroy parameter is taken into account
+  during :reject_if => :all_blank (fixes #2937)
+
+  [Aaron Christy]
+
+*Rails 3.1.2 (unreleased)*
+
+* Fix bug where building the conditions of a nested through association could potentially
+  modify the conditions of the through and/or source association. If you have experienced
+  bugs with conditions appearing in the wrong queries when using nested through associations,
+  this probably solves your problems. [GH #3271]
+
+  [Jon Leighton]
+
+* If a record is removed from a has_many :through, all of the join records relating to that
+  record should also be removed from the through association's target.
+
+  [Jon Leighton]
+
+* Fix adding multiple instances of the same record to a has_many :through. [GH #3425]
+
+  [Jon Leighton]
+
+* Fix creating records in a through association with a polymorphic source type. [GH #3247]
+
+  [Jon Leighton]
+
+*Rails 3.1.1 (October 7, 2011)*
+
+* Add deprecation for the preload_associations method. Fixes #3022.
+
+  [Jon Leighton]
+
+* Don't require a DB connection when loading a model that uses set_primary_key. GH #2807.
+
+  [Jon Leighton]
+
+* Fix using select() with a habtm association, e.g. Person.friends.select(:name). GH #3030 and
+  #2923.
+
+  [Hendy Tanata]
+
+* Fix belongs_to polymorphic with custom primary key on target. GH #3104.
+
+  [Jon Leighton]
+
+* CollectionProxy#replace should change the DB records rather than just mutating the array.
+  Fixes #3020.
+
+  [Jon Leighton]
+
+* LRU cache in mysql and sqlite are now per-process caches.
+
+	* lib/active_record/connection_adapters/mysql_adapter.rb: LRU cache
+	  keys are per process id.
+	* lib/active_record/connection_adapters/sqlite_adapter.rb: ditto
+
+  [Aaron Patterson]
+
+* Support bulk change_table in mysql2 adapter, as well as the mysql one. [Jon Leighton]
+
+* If multiple parameters are sent representing a date, and some are blank, the
+resulting object is nil. In previous releases those values defaulted to 1. This
+only affects existing but blank parameters, missing ones still raise an error.
+[Akira Matsuda]
+
+* ActiveRecord::Base.establish_connection now takes a string that contains
+a URI that specifies the connection configuration.  For example:
+
+    ActiveRecord::Base.establish_connection 'postgres://localhost/foo'
+
+* Active Record's dynamic finder will now raise the error if you passing in less number of arguments than what you call in method signature.
+
+  So if you were doing this and expecting the second argument to be nil:
+
+    User.find_by_username_and_group("sikachu")
+
+  You'll now get `ArgumentError: wrong number of arguments (1 for 2).` You'll then have to do this:
+
+    User.find_by_username_and_group("sikachu", nil)
+
+  [Prem Sichanugrist]
+
+
+*Rails 3.1.0 (August 30, 2011)*
+
+* Add a proxy_association method to association proxies, which can be called by association
+  extensions to access information about the association. This replaces proxy_owner etc with
+  proxy_association.owner.
+
+  [Jon Leighton]
+
+* ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature.
+
+  Before: def build_association(*options)
+  After:  def build_association(*options, &block)
+
+  Users who are redefining this method to extend functionality should ensure that the block is
+  passed through to ActiveRecord::Base#new.
+
+  This change is necessary to fix https://github.com/rails/rails/issues/1842.
+
+  [Jon Leighton]
+
+* AR#pluralize_table_names can be used to singularize/pluralize table name of an individual model:
+
+    class User < ActiveRecord::Base
+      self.pluralize_table_names = false
+    end
+
+  Previously this could only be set globally for all models through ActiveRecord::Base.pluralize_table_names. [Guillermo Iguaran]
 
 * Add block setting of attributes to singular associations:
