-*   Implements an evented file system monitor to asynchronously detect changes
-    in the application source code, routes, locales, etc.
+## Rails 5.0.0.beta1 (December 18, 2015) ##
 
-    To opt-in load the [listen](https://github.com/guard/listen) gem in `Gemfile`:
+*   No changes.
+
+
+*   Add thread_m/cattr_accessor/reader/writer suite of methods for declaring class and module variables that live per-thread.
+    This makes it easy to declare per-thread globals that are encapsulated. Note: This is a sharp edge. A wild proliferation
+    of globals is A Bad Thing. But like other sharp tools, when it's right, it's right.
+
+    Here's an example of a simple event tracking system where the object being tracked needs not pass a creator that it
+    doesn't need itself along:
+
+    module Current
+      thread_mattr_accessor :account
+      thread_mattr_accessor :user
+      
+      def self.reset() self.account = self.user = nil end
+    end
+
+    class ApplicationController < ActiveController::Base
+      before_action :set_current
+      after_action { Current.reset }
+    
+      private
+        def set_current
+          Current.account = Account.find(params[:account_id])
+          Current.user    = Current.account.users.find(params[:user_id])
+        end
+    end
+
+    class MessagesController < ApplicationController
+      def create
+        @message = Message.create!(message_params)
+      end
+    end
+
+    class Message < ApplicationRecord
+      has_many :events
+      after_create :track_created
+    
+      private
+        def track_created
+          events.create! origin: self, action: :create
+        end
+    end
+
+    class Event < ApplicationRecord
+      belongs_to :creator, class_name: 'User'
+      before_validation { self.creator ||= Current.user }
+    end
+
+    *DHH*
+
+
+*   Deprecated `Module#qualified_const_` in favour of the builtin Module#const_
+    methods.
+
+    *Genadi Samokovarov*
+
+*   Deprecate passing string to define callback.
+
+    *Yuichiro Kaneko*
+
+*   `ActiveSupport::Cache::Store#namespaced_key`, 
+    `ActiveSupport::Cache::MemCachedStore#escape_key`, and 
+    `ActiveSupport::Cache::FileStore#key_file_path` 
+    are deprecated and replaced with `normalize_key` that now calls `super`.
+
+    `ActiveSupport::Cache::LocaleCache#set_cache_value` is deprecated and replaced with `write_cache_value`.
+
+    *Michael Grosser*
+
+*   Implements an evented file watcher to asynchronously detect changes in the
+    application source code, routes, locales, etc.
+
+    This watcher is disabled by default, applications my enable it in the configuration:
+
+        # config/environments/development.rb
+        config.file_watcher = ActiveSupport::EventedFileUpdateChecker
+
+    This feature depends on the [listen](https://github.com/guard/listen) gem:
 
         group :development do
-          gem 'listen', '~> 3.0.4'
+          gem 'listen', '~> 3.0.5'
         end
 
     *Puneet Agarwal* and *Xavier Noria*
 
-*   Added `Time#days_in_year` to return the number of days in the given year, or the
+*   Added `Time.days_in_year` to return the number of days in the given year, or the
     current year if no argument is provided.
