* Change JSON to encode %w(< > &) as 4 digit hex codes to be in compliance with the JSON spec. Closes #9975 [Josh Peek, Cheah Chu Yeow, Tim Pope]
* Fix JSON encoding/decoding bugs dealing with /'s. Closes #9990 [Rick, theamazingrando]
* Introduce a base class for all test cases used by rails applications. ActiveSupport::TestCase [Koz]
The intention is to use this to reduce the amount of monkeypatching / overriding that
is done to test/unit's classes.
* Document Enumerable and Hash #to_json. #9970 [Cheah Chu Yeow]
* Hash#to_xml handles symbol values. #9954 [Assaf]
* Hash#symbolize_keys behaves well with integer keys. #9890 [PotatoSalad]
* Multibyte: String#slice supports regexp argument. #9646 [yob]
* object.duplicable? returns true if object.dup is safe. False for nil, true, false, symbols, and numbers; true otherwise. #9333 [sur]

* Added support for pluralization with a different starting letter than the singular version (cow/kine) #4929 [norri_b/hasmanyjosh]
* Demote Hash#to_xml to use XmlSimple#xml_in_string so it can't read files or stdin. #8453 [candlerb, Jeremy Kemper]
* Backport clean_logger changes to support ruby 1.8.2 [mislav]
* Added proper handling of arrays #8537 [hasmanyjosh]
Hash.from_xml '<images></images>'
# => {:images => nil}
Hash.from_xml '<images><image>foo.jpg</image></images>'
# => {:images => {:image => "foo.jpg"}}

* Added assert_difference and assert_no_difference to test/unit assertions [Tobias Luetke]
* Removed breakpointer and Binding.of_caller in favor of relying on ruby-debug by Kent Sibilev since the breakpointer has been broken since Ruby 1.8.4 and will not be coming back [DHH]
* Added parsing of file type in Hash.xml_in so you can easily do file uploads with base64 from an API [DHH]
<avatar type="file" name="me.jpg" content_type="image/jpg">R0lGODlhkACZAPUAAM5lcfjrtMQCG=\n</avatar>
attributes = { :person => { :name => "David", :avatar => #<StringIO> } }
attributes[:person][:avatar].content_type # => "image/jpg"

* Stop using defined? in Dependencies.qualified_const_defined? since defined? may invoke const_missing. [Nicholas Seckar]
* Dependencies can autoload directories of nested classes. [Jeremy Kemper]
invoice.rb class Invoice
invoice/lineitem.rb class Invoice::Lineitem
* Add Deprecation.silence so that Reloadable does not scold itself. [Nicholas Seckar]
* Add debugging logging to Dependencies. Currently can be enabled with Dependencies.log_activity = true; adding to Initializer and documenting is forthcoming. [Nicholas Seckar]
* Replace Reloadable with improvements to the Dependencies mechanism. [Nicholas Seckar]
* DateTime#to_time gives hour/minute/second resolution. #5747 []
* attr_internal to support namespacing and deprecation. Like attr_* except backed by internally-named instance variable. Set attr_internal_naming_format to change the format from the default '@_%s'. [Jeremy Kemper]

e.title # => "Superstars"
e.subject # => "Superstars"
e.subject? # => true
e.subject = "Megastars"
e.title # => "Megastars"
* Deprecation: easier to work with warning behavior as procs; default behaviors for each environment so users needn't update env.rb; and testing pleasure with assert_deprecated, assert_not_deprecated. [Jeremy Kemper]
By default, test prints to $stderr, dev logs, production ignores.
Provide your own per-environment in e.g. config/environments/development.rb:
ActiveSupport::Deprecation.behavior = { |message| raise message }
* First cut of the Rails Deprecation system. [Koz]
* Strip boolean XML content before checking for 'true' [Rick Olson]
* Customize default BigDecimal formatting. References #5672 []
* Correctly convert <foo nil="true"> to nil when using Hash.create_from_xml. [Rick]
* Optional identity for Enumerable#sum defaults to zero. #5657 []
* HashWithIndifferentAccess shouldn't confuse false and nil. #5601 []
* Fixed HashWithIndifferentAccess#default #5586 []

This is instead of payments.inject(0) { |sum, p| sum + p.price }
* Correct and clarify Array#to_sentence docs. #5458 []
* alias_method_chain preserves method punctuation so foo, foo?, and foo! may be chained with the same feature. [Jeremy Kemper]
alias_method_chain :save!, :validation
is equivalent to
alias_method :save_without_validation!, :save!
alias_method :save!, :save_with_validation!
* Enhance Symbol#to_proc so it works with list objects, such as multi-dimensional arrays. Closes #5295 []. Example:
{1 => "one", 2 => "two", 3 => "three"}.sort_by(&:first).map(&:last)
#=> ["one", "two", "three"]
* Added Hash.create_from_xml(string) which will create a hash from a XML string and even typecast if possible [DHH]. Example:
Hash.create_from_xml <<-EOT
<title>This is a note</title>
<created-at type="date">2004-10-10</created-at>
...would return:
{ :note => { :title => "This is a note", :created_at =>, 10, 10) } }
* Added Jim Weirich's excellent FlexMock class to vendor (Copyright 2003, 2004 by Jim Weirich ( -- it's not automatically required, though, so require 'flexmock' is still necessary [DHH]
* Fixed that Module#alias_method_chain should work with both foo? foo! and foo at the same time #4954 []
* to_xml fixes, features, and speedup: introduce :dasherize option that converts updated_at to updated-at if true (the existing default); binary columns get encoding="base64" attribute; nil values get nil="true" attribute to distinguish empty values; add type information for float columns; allow arbitrarily deep :include; include SQL type information as the type attribute. #4989 [Blair Zajac <>]
* Add OrderedHash#values. [Sam Stephenson]
* Added Array#to_s(:db) that'll produce a comma-separated list of ids [DHH]. Example:
Purchase.find(:all, :conditions => "product_id IN (#{shops.products.to_s(:db)})"
* Normalize classify's argument to a String so that it plays nice with Symbols. [Marcel Molina Jr.]
* Strip out leading schema name in classify. References #5139. []
* Remove Enumerable#first_match since break(value) handles the use case well enough. [Nicholas Seckar]
Enumerable#first_match was like detect, but instead of returning the matching element, the yielded value returned. For example:
user_xml = adapters(:from => User, :to => Xml).first_match do |adapter|
adapter.adapt @user
But this is just as easily done with:
user_xml = adapters(:from => User, :to => Xml).each do
break adapter.adapt(@user)
* Make Array#in_groups_of just return the grouped collection if a block isn't given. [Marcel Molina Jr.]
* Don't destroy a HashWithIndifferentAccess if symbolize_keys! or stringify_keys! is called on it. Closes #5076. [Marcel Molina Jr.,]
* Document Module::delegate. #5002 []
* Replace alias method chaining with Module#alias_method_chain. [Marcel Molina Jr.]

* Replace Ruby's deprecated append_features in favor of included. [Marcel Molina Jr.]
* Allow default options in with_options to be overridden. Closes #4480. []
* Added Module#alias_method_chain [Jamis Buck]

*1.3.1* (April 6th, 2006)
* Clean paths inside of exception messages and traces. [Nicholas Seckar]
* Add Pathname.clean_within for cleaning all the paths inside of a string. [Nicholas Seckar]
* provide an empty Dependencies::LoadingModule.load which prints deprecation warnings. Lets 1.0 applications function with .13-style environment.rb.
*1.3.0* (March 27th, 2006)
* When possible, avoid incorrectly obtaining constants from parent modules. Fixes #4221. [Nicholas Seckar]
* Add more tests for dependencies; refactor existing cases. [Nicholas Seckar]
* Move Module#parent and Module#as_load_path into core_ext. Add Module#parent. [Nicholas Seckar]
* Add CachingTools::HashCaching to simplify the creation of nested, autofilling hashes. [Nicholas Seckar]
* Remove a hack intended to avoid unloading the same class twice, but which would not work anyways. [Nicholas Seckar]
* Update Object.subclasses_of to locate nested classes. This affects Object.remove_subclasses_of in that nested classes will now be unloaded. [Nicholas Seckar]
* Update Object.remove_subclasses_of to use Class.remove_class, reducing duplication. [Nicholas Seckar]
* Added Fixnum#seconds for consistency, so you can say 5.minutes + 30.seconds instead of 5.minutes + 30 #4389 [François Beausoleil]
* Added option to String#camelize to generate lower-cased camel case by passing in :lower, like "super_man".camelize(:lower) # => "superMan" [DHH]
* Added Hash#diff to show the difference between two hashes [Chris McGrath]
* Added Time#advance to do precise time time calculations for cases where a month being approximated to 30 days won't do #1860 [Rick Olson]
* Enhance Inflector.underscore to convert '-' into '_' (as the inverse of Inflector.dasherize) [Jamis Buck]
* Switched to_xml to use the xml schema format for datetimes. This allows the encoding of time zones and should improve operability. [Koz]
* Added a note to the documentation for the Date related Numeric extensions to indicate that they're
approximations and shouldn't be used for critical calculations. [Koz]
* Added Hash#to_xml and Array#to_xml that makes it much easier to produce XML from basic structures [DHH]. Examples:
{ :name => "David", :street_name => "Paulina", :age => 26, :moved_on =>, 11, 15) }.to_xml
<age type="integer">26</age>
<moved-on type="date">2005-11-15</moved-on>
* Moved Jim Weirich's wonderful Builder from Action Pack to Active Support (it's simply too useful to be stuck in AP) [DHH]
* Fixed that Array#to_sentence will return "" on an empty array instead of ", and" #3842, #4031 []
* Add Enumerable#group_by for grouping collections based on the result of some
block. Useful, for example, for grouping records by date.
latest_transcripts.group_by(&:day).each do |day, transcripts|
p "#{day} -> #{ * ', '}"
"2006-03-01 -> Transcript"
"2006-02-28 -> Transcript"
"2006-02-27 -> Transcript, Transcript"
"2006-02-26 -> Transcript, Transcript"
Add Array#in_groups_of, for iterating over an array in groups of a certain
%w(1 2 3 4 5 6 7).in_groups_of(3) {|g| p g}
["1", "2", "3"]
["4", "5", "6"]
["7", nil, nil]
[Marcel Molina Jr., Sam Stephenson]
* Added Kernel#daemonize to turn the current process into a daemon that can be killed with a TERM signal [DHH]
* Add 'around' methods to Logger, to make it easy to log before and after messages for a given block as requested in #3809. [Michael Koziarski] Example:
logger.around_info("Start rendering component (#{options.inspect}): ",
"\n\nEnd of component rendering") { yield }
* Added Time#beginning_of_quarter #3607 []
* Fix Object.subclasses_of to only return currently defined objects [Jonathan Viney <>]
* Fix constantize to properly handle names beginning with '::'. [Nicholas Seckar]
* Make String#last return the string instead of nil when it is shorter than the limit [Scott Barron].
* Added delegation support to Module that allows multiple delegations at once (unlike Forwardable in the stdlib) [DHH]. Example:
class Account < ActiveRecord::Base
has_one :subscription
delegate :free?, :paying?, :to => :subscription
delegate :overdue?, :to => "subscription.last_payment"
end # =>
account.overdue? # => account.subscription.last_payment.overdue?
* Fix Reloadable to handle the case where a class that has been 'removed' has not yet been garbage collected. [Nicholas Seckar]
* Don't allow Reloadable to be included into Modules.
* Remove LoadingModule. [Nicholas Seckar]
* Add documentation for Reloadable::Subclasses. [Nicholas Seckar]
* Add Reloadable::Subclasses which handles the common case where a base class should not be reloaded, but its subclasses should be. [Nicholas Seckar]
* Further improvements to reloading code [Nicholas Seckar, Trevor Squires]
- All classes/modules which include Reloadable can define reloadable? for fine grained control of reloading
- Class.remove_class uses Module#parent to access the parent module
- Class.remove_class expanded to handle multiple classes in a single call
- LoadingModule.clear! has been removed as it is no longer required
- Module#remove_classes_including has been removed in favor of Reloadable.reloadable_classes
* Added reusable reloading support through the inclusion of the Relodable module that all subclasses of ActiveRecord::Base, ActiveRecord::Observer, ActiveController::Base, and ActionMailer::Base automatically gets. This means that these classes will be reloaded by the dispatcher when Dependencies.mechanism = :load. You can make your own models reloadable easily:
class Setting
include Reloadable
Reloading a class is done by removing its constant which will cause it to be loaded again on the next reference. [DHH]
* Added auto-loading support for classes in modules, so Conductor::Migration will look for conductor/migration.rb and Conductor::Database::Settings will look for conductor/database/settings.rb [Nicholas Seckar]
* Add Object#instance_exec, like instance_eval but passes its arguments to the block. (Active Support will not override the Ruby 1.9 implementation of this method.) [Sam Stephenson]
* Add Proc#bind(object) for changing a proc or block's self by returning a Method bound to the given object. Based on why the lucky stiff's "cloaker" method. [Sam Stephenson]
* Fix merge and dup for hashes with indifferent access #3404 []
* Fix the requires in option_merger_test to unbreak AS tests. [Sam Stephenson]
* Make HashWithIndifferentAccess#update behave like Hash#update by returning the hash. #3419, #3425 [,, Marcel Molina Jr.]
* Add ActiveSupport::JSON and Object#to_json for converting Ruby objects to JSON strings. [Sam Stephenson]
* Add Object#with_options for DRYing up multiple calls to methods having shared options. [Sam Stephenson] Example:
ActionController::Routing::Routes.draw do |map|
# Account routes
map.with_options(:controller => 'account') do |account|
account.home '', :action => 'dashboard'
account.signup 'signup', :action => 'new'
account.logout 'logout', :action => 'logout'
* Introduce Dependencies.warnings_on_first_load setting. If true, enables warnings on first load of a require_dependency. Otherwise, loads without warnings. Disabled (set to false) by default. [Jeremy Kemper]
* Active Support is warnings-safe. #1792 [Eric Hodel]
* Introduce enable_warnings counterpart to silence_warnings. Turn warnings on when loading a file for the first time if Dependencies.mechanism == :load. Common mistakes such as redefined methods will print warnings to stderr. [Jeremy Kemper]
* Add Symbol#to_proc, which allows for, e.g. [:foo, :bar].map(&:to_s). [Marcel Molina Jr.]
* Added the following methods [Marcel Molina Jr., Sam Stephenson]:
* Object#copy_instance_variables_from(object) to copy instance variables from one object to another
* Object#extended_by to get an instance's included/extended modules
* Object#extend_with_included_modules_from(object) to extend an instance with the modules from another instance
*1.2.5* (December 13th, 2005)
* Become part of Rails 1.0
* Rename Version constant to VERSION. #2802 [Marcel Molina Jr.]
*1.2.3* (November 7th, 2005)
* Change Inflector#constantize to use eval instead of const_get. [Nicholas Seckar]
* Fix const_missing handler to ignore the trailing '.rb' on files when comparing paths. [Nicholas Seckar]
* Define kernel.rb methods in "class Object" instead of "module Kernel" to work around a Windows peculiarity [Sam Stephenson]
* Fix broken tests caused by incomplete loading of active support. [Nicholas Seckar]
* Fix status pluralization bug so status_codes doesn't get pluralized as statuses_code. #2758 []
* Added Kernel#silence_stderr to silence stderr for the duration of the given block [Sam Stephenson]
* Changed Kernel#` to print a message to stderr (like Unix) instead of raising Errno::ENOENT on Win32 [Sam Stephenson]
* Changed 0.blank? to false rather than true since it violates everyone's expectation of blankness. #2518, #2705 []
* When loading classes using const_missing, raise a NameError if and only if the file we tried to load was not present. [Nicholas Seckar]
* Added petabytes and exebytes to numeric extensions #2397 []
* Added Time#end_of_month to accompany Time#beginning_of_month #2514 [Jens-Christian Fischer]
*1.2.2* (October 26th, 2005)
* Set Logger.silencer = false to disable Logger#silence. Useful for debugging fixtures.
* Add title case method to String to do, e.g., 'action_web_service'.titlecase # => 'Action Web Service'. [Marcel Molina Jr.]
*1.2.1* (October 19th, 2005)
* Classify generated routing code as framework code to avoid appearing in application traces. [Nicholas Seckar]
* Show all framework frames in the framework trace. [Nicholas Seckar]
*1.2.0* (October 16th, 2005)
* Update Exception extension to show the first few framework frames in an application trace. [Nicholas Seckar]
* Added Exception extension to provide support for clean backtraces. [Nicholas Seckar]
* Updated whiny nil to be more concise and useful. [Nicholas Seckar]
* Added Enumerable#first_match [Nicholas Seckar]
* Fixed that Time#change should also reset usec when also resetting minutes #2459 []
* Fix Logger compatibility for distributions that don't keep Ruby and its standard library in sync.
* Replace '%e' from long and short time formats as Windows does not support it. #2344. [Tom Ward <>]
* Added to_s(:db) to Range, so you can get "BETWEEN '2005-12-10' AND '2005-12-12'" from, 12, 10), 12, 12) (and likewise with Times)
* Moved require_library_or_gem into Kernel. #1992 [Michael Schuerig <>]
* Add :rfc822 as an option for Time#to_s (to get rfc822-formatted times)
* Chain the const_missing hook to any previously existing hook so rails can play nicely with rake
* Clean logger is compatible with both 1.8.2 and 1.8.3 Logger. #2263 [Michael Schuerig <>]
* Added native, faster implementations of .blank? for the core types #2286 [skae]
* Fixed clean logger to work with Ruby 1.8.3 Logger class #2245
* Fixed memory leak with Active Record classes when Dependencies.mechanism = :load #1704 []
* Fixed Inflector.underscore for use with acronyms, so HTML becomes html instead of htm_l #2173 []

* Fixed inflections for status, quiz, move #2056 []
* Added Hash#reverse_merge, Hash#reverse_merge!, and Hash#reverse_update to ease the use of default options
* Added Array#to_sentence that'll turn ['one', 'two', 'three'] into "one, two, and three" #2157 []
* Added Kernel#silence_warnings to turn off warnings temporarily for the passed block
* Added String#starts_with? and String#ends_with? #2118 []
* Added easy extendability to the inflector through Inflector.inflections (using the Inflector::Inflections singleton class). Examples:
Inflector.inflections do |inflect|
inflect.plural /^(ox)$/i, '\1\2en'
inflect.singular /^(ox)en/i, '\1'
inflect.irregular 'octopus', 'octopi'
inflect.uncountable "equipment"
* Added String#at, String#from, String#to, String#first, String#last in ActiveSupport::CoreExtensions::String::Access to ease access to individual characters and substrings in a string serving basically as human names for range access.
* Make Time#last_month work when invoked on the 31st of a month.
* Add Time.days_in_month, and make Time#next_month work when invoked on the 31st of a month
* Fixed that Time#midnight would have a non-zero usec on some platforms #1836
* Fixed inflections of "index/indices" #1766 []
* Added stripping of _id to String#humanize, so "employee_id" becomes "Employee" #1574 [Justin French]
* Factor Fixnum and Bignum extensions into Integer extensions [Nicholas Seckar]
* Hooked #ordinalize into Fixnum and Bignum classes. [Nicholas Seckar, danp]
* Added Fixnum#ordinalize to turn 1.ordinalize to "1st", 3.ordinalize to "3rd", and 10.ordinalize to "10th" and so on #1724 []
*1.1.1* (11 July, 2005)
* Added more efficient implementation of the development mode reset of classes #1638 [Chris McGrath]
*1.1.0* (6 July, 2005)
* Fixed conflict with Glue gem #1606 [Rick Olson]
* Added new rules to the Inflector to deal with more unusual plurals mouse/louse => mice/lice, information => information, ox => oxen, virus => viri, archive => archives #1571, #1583, #1490, #1599, #1608 []
* Fixed memory leak with Object#remove_subclasses_of, which inflicted a Rails application running in development mode with a ~20KB leak per request #1289 []
* Made 1.year == 365.25.days to account for leap years. This allows you to do User.find(:all, :conditions => ['birthday > ?', 50.years.ago]) without losing a lot of days. #1488 []
* Added an exception if calling id on nil to WhinyNil #584 []
* Added Fix/Bignum#multiple_of? which returns true on 14.multiple_of?(7) and false on 16.multiple_of?(7) #1464 [Thomas Fuchs]
* Added even? and odd? to work with Bignums in addition to Fixnums #1464 [Thomas Fuchs]
* Fixed Time#at_beginning_of_week returned the next Monday instead of the previous one when called on a Sunday #1403 []
* Increased the speed of indifferent hash access by using Hash#default. #1436 [Nicholas Seckar]
* Added that " " is now also blank? (using strip if available)
* Fixed Dependencies so all modules are able to load missing constants #1173 [Nicholas Seckar]
* Fixed the Inflector to underscore strings containing numbers, so Area51Controller becomes area51_controller #1176 [Nicholas Seckar]
* Fixed that HashWithIndifferentAccess stringified all keys including symbols, ints, objects, and arrays #1162 [Nicholas Seckar]
* Fixed Time#last_year to go back in time, not forward #1278 []
* Fixed the pluralization of analysis to analyses #1295 []
* Fixed that Time.local(2005,12).months_since(1) would raise "ArgumentError: argument out of range" #1311 []
* Added silencing to the default Logger class
*1.0.4* (19th April, 2005)
* Fixed that in some circumstances controllers outside of modules may have hidden ones inside modules. For example, admin/content might have been hidden by /content. #1075 [Nicholas Seckar]
* Fixed inflection of perspectives and similar words #1045 []
* Added Fixnum#even? and Fixnum#odd?
* Fixed problem with classes being required twice. Object#const_missing now uses require_dependency to load files. It used to use require_or_load which would cause models to be loaded twice, which was not good for validations and other class methods #971 [Nicholas Seckar]
*1.0.3* (27th March, 2005)
* Fixed Inflector.pluralize to handle capitalized words #932 [Jeremy Kemper]
* Added Object#suppress which allows you to make a saner choice around with exceptions to swallow #980. Example:
suppress(ZeroDivisionError) { 1/0 }
...instead of:
1/0 rescue nil # BAD, EVIL, DIRTY.
*1.0.2* (22th March, 2005)
* Added Kernel#returning -- a Ruby-ized realization of the K combinator, courtesy of Mikael Brockman.
def foo
returning values = [] do
values << 'bar'
values << 'baz'
foo # => ['bar', 'baz']
*1.0.1* (7th March, 2005)
* Fixed Hash#indifferent_access to also deal with include? and fetch and nested hashes #726 [Nicholas Seckar]
* Added Object#blank? -- see #783 [_why the lucky stiff]
* Added inflection rules for "sh" words, like "wish" and "fish" #755 []
* Fixed an exception when using Ajax based requests from Safari because Safari appends a \000 to the post body. Symbols can't have \000 in them so indifferent access would throw an exception in the constructor. Indifferent hashes now use strings internally instead. #746 [Tobias Luetke]
* Added String#to_time and String#to_date for wrapping ParseDate
*1.0.0* (24th February, 2005)
* Added TimeZone as the first of a number of value objects that among others Active Record can use rich value objects using composed_of #688 [Jamis Buck]
* Added Date::Conversions for getting dates in different convenient string representations and other objects
* Added Time::Conversions for getting times in different convenient string representations and other objects
* Added Time::Calculations to ask for things like,, #580 [DP|Flurin]. Examples:
"Later today" =>,
"Tomorrow morning" => now.tomorrow.change(:hour => 9),
"Tomorrow afternoon" => now.tomorrow.change(:hour => 14),
"In a couple of days" => now.tomorrow.tomorrow.change(:hour => 9),
"Next monday" => now.next_week.change(:hour => 9),
"In a month" => now.next_month.change(:hour => 9),
"In 6 months" => now.months_since(6).change(:hour => 9),
"In a year" => => 9)
* Upgraded to breakpoint 92 which fixes:
* overload IRB.parse_opts(), fixes #443
=> breakpoints in tests work even when running them via rake
* untaint handlers, might fix an issue discussed on the Rails ML
* added verbose mode to breakpoint_client
* less noise caused by breakpoint_client by default
* ignored TerminateLineInput exception in signal handler
=> quiet exit on Ctrl-C
* Fixed Inflector for words like "news" and "series" that are the same in plural and singular #603 [echion], #615 [marcenuc]
* Added Hash#stringify_keys and Hash#stringify_keys!
* Added IndifferentAccess as a way to wrap a hash by a symbol-based store that also can be accessed by string keys
* Added Inflector.constantize to turn "Admin::User" into a reference for the constant Admin::User
* Added that Inflector.camelize and Inflector.underscore can deal with modules like turning "Admin::User" into "admin/user" and back
* Added Inflector.humanize to turn attribute names like employee_salary into "Employee salary". Used by automated error reporting in AR.
* Added availability of class inheritable attributes to the masses #477 [Jeremy Kemper]
class Foo
class_inheritable_reader :read_me
class_inheritable_writer :write_me
class_inheritable_accessor :read_and_write_me
class_inheritable_array :read_and_concat_me
class_inheritable_hash :read_and_update_me
# Bar gets a clone of (not a reference to) Foo's attributes.
class Bar < Foo
Bar.read_and_write_me == Foo.read_and_write_me
Bar.read_and_write_me = 'bar'
Bar.read_and_write_me != Foo.read_and_write_me
* Added Inflections as an extension on String, so Inflector.pluralize(Inflector.classify(name)) becomes name.classify.pluralize #476 [Jeremy Kemper]
* Added Byte operations to Numeric, so 5.5.megabytes + 200.kilobytes #461 [Marcel Molina]
* Fixed that Dependencies.reload can't load the same file twice #420 [Kent Sibilev]
* Added Fixnum#ago/until, Fixnum#since/from_now #450 [Jeremy Kemper]
* Added that Inflector now accepts Symbols and Classes by calling .to_s on the word supplied
* Added time unit extensions to Fixnum that'll return the period in seconds, like 2.days + 4.hours.
