• No Changes, just a version bump.

Rails 3.0.0 (August 29, 2010)

• Implemented String#strip_heredoc. fxn

• Pluggable cache stores: setting config.cache_store = "custom_store" will require 'active_support/cache/custom_store' and look for the CustomStore constant. #5486 Mike Perham

• Removed Object#returning, Object#tap should be used instead. Santiago Pastorino

• Deprecation behavior is no longer hardcoded to the name of the environment. Instead, it is set via config.active_support.deprecation and can be one of :log, :stderr or :notify. :notify is a new style that sends the warning via ActiveSupport::Notifications, and is the new default for production Yehuda Katz

• Renamed ActiveSupport::Dependecies.load_(once_)paths to autoload_(once_)paths. fxn

• Added ActiveSupport::FileUpdateChecker to execute a block only if a set of files changed, used by Router and I18n locale files. José Valim

• Added ActiveSupport::DescendantsTracker to track descendants with support to constants reloading. José Valim

• ActiveSupport::OrderedHash#merge and #merge! accept a block. #4838 Paul Mucur, fxn

• Date#to_time handles properly years in the range 0..138. fxn

• Deprecate {{}} as interpolation syntax for I18n in favor of %{} José Valim

• Array#to_xml is more powerful and able to handle the same types as Hash#to_xml #4490 Neeraj Singh

• Harmonize the caching API and refactor the backends. #4452 Brian Durand All caches:

  • Add default options to initializer that will be sent to all read, write, fetch, exist?, increment, and decrement
  • Add support for the :expires_in option to fetch and write for all caches. Cache entries are stored with the create timestamp and a ttl so that expiration can be handled independently of the implementation.
  • Add support for a :namespace option. This can be used to set a global prefix for cache entries.
  • Deprecate expand_cache_key on ActiveSupport::Cache and move it to ActionController::Caching and ActionDispatch::Http::Cache since the logic in the method used some Rails specific environment variables and was only used by ActionPack classes. Not very DRY but there didn't seem to be a good shared spot and ActiveSupport really shouldn't be Rails specific.
  • Add support for :race_condition_ttl to fetch. This setting can prevent race conditions on fetch calls where several processes try to regenerate a recently expired entry at once.
  • Add support for :compress option to fetch and write which will compress any data over a configurable threshold.
  • Nil values can now be stored in the cache and are distinct from cache misses for fetch.
  • Easier API to create new implementations. Just need to implement the methods read_entry, write_entry, and delete_entry instead of overwriting existing methods.
  • Since all cache implementations support storing objects, update the docs to state that ActiveCache::Cache::Store implementations should store objects. Keys, however, must be strings since some implementations require that.
  • Increase test coverage.
  • Document methods which are provided as convenience but which may not be universally available.

  MemoryStore:

  • MemoryStore can now safely be used as the cache for single server sites.
  • Make thread safe so that the default cache implementation used by Rails is thread safe. The overhead is minimal and it is still the fastest store available.
  • Provide :size initialization option indicating the maximum size of the cache in memory (defaults to 32Mb).
  • Add prune logic that removes the least recently used cache entries to keep the cache size from exceeding the max.
  • Deprecated SynchronizedMemoryStore since it isn't needed anymore.

  FileStore:

  • Escape key values so they will work as file names on all file systems, be consistent, and case sensitive
  • Use a hash algorithm to segment the cache into sub directories so that a large cache doesn't exceed file system limits.
  • FileStore can be slow so implement the LocalCache strategy to cache reads for the duration of a request.
  • Add cleanup method to keep the disk from filling up with expired entries.
  • Fix increment and decrement to use file system locks so they are consistent between processes.

  MemCacheStore:

  • Support all keys. Previously keys with spaces in them would fail
  • Deprecate CompressedMemCacheStore since it isn't needed anymore (use :compress => true)

• JSON: encode objects that don't have a native JSON representation using to_hash, if available, instead of instance_values (the old fallback) or to_s (other encoders' default). Encode BigDecimal and Regexp encode as strings to conform with other encoders. Try to transcode non-UTF-8 strings. Jeremy Kemper

• HashWithIndifferentAccess: remove inherited symbolize_keys! since its keys are always strings. Santiago Pastorino

• Improve transliteration quality. #4374 Norman Clarke

• Speed up and add Ruby 1.9 support for ActiveSupport::Multibyte::Chars#tidy_bytes. #4350 Norman Clarke

• Reduced load time by deferring configuration of classes using ActiveSupport::on_load(:component_name) YK

• Rename #metaclass to #singleton_class now that ruby-core has decided JK

• New assertions assert_blank and assert_present. #4299 Juanjo Bazan

• Use Object#singleton_class instead of #metaclass. Prefer Ruby's choice. Jeremy Kemper

• JSON backend for YAJL. Preferred if available. #2666 Brian Lopez

• Introduce class_attribute to declare inheritable class attributes. Writing an attribute on a subclass behaves just like overriding the superclass reader method. Unifies and replaces most usage of cattr_accessor, class_inheritable_attribute, superclass_delegating_attribute, and extlib_inheritable_attribute. Jeremy Kemper, Yehuda Katz

• Time#- with a DateTime argument behaves the same as with a Time argument, i.e. returns the difference between self and arg as a Float #3476 Geoff Buesing

• YAML serialization for OrderedHash. #3608 Gregor Schmidt

• Update bundled TZInfo to v0.3.16 Geoff Buesing

• Georgetown TimeZone is now mapped to "America/Guyana" instead of "America/Argentina/San_Juan" #1821 Geoff Buesing, Reuben Sivan

• Changed the default ActiveSupport.use_standard_json_time_format from false to true and ActiveSupport.escape_html_entities_in_json from true to false to match previously announced Rails 3 defaults DHH

• Added Object#presence that returns the object if it's #present? otherwise returns nil DHH/Colin Kelley

• Add Enumerable#exclude? to bring parity to Enumerable#include? and avoid if !x.include?/else calls DHH

• Update Edinburgh TimeZone to use "Europe/London" instead of "Europe/Dublin" #3310 Phil Ross

• Update bundled TZInfo to v0.3.15 Geoff Buesing

• JSON: +Object#to_json+ calls +as_json+ to coerce itself into something natively encodable like +Hash+, +Integer+, or +String+. Override +as_json+ instead of +to_json+ so you're JSON library agnostic. Jeremy Kemper

• String #to_time and #to_datetime: handle fractional seconds #864 Jason Frey

• Update bundled TZInfo to v0.3.13 Geoff Buesing

• Allow MemCacheStore to be initialized with a MemCache-like object instead of addresses and options Bryan Helmkamp

• Change spelling of Kyev timezone to Kyiv #2613 Alexander Dymo

• Add ActiveSupport.parse_json_times to disable time parsing in JSON backends that don't support it or don't need it. rick

• Add pluggable JSON backends with support for the JSON gem. rick Example: ActiveSupport::JSON.backend = "JSONGem"

  All internal Rails JSON encoding is now handled by ActiveSupport::JSON.encode(). Use of #to_json is not recommended, as it may clash with other libraries that overwrite it. However, you can recover Rails specific functionality if you really want to use #to_json.

  gem 'json'
  ActiveSupport::JSON.backend = "JSONGem"
  
  class ActiveRecord::Base
    alias to_json rails_to_json
  end
  

• require 'active_support' no longer orders the whole menu of core extensions. Ask for just what you need: e.g. require 'active_support/core/time' to use timezones, durations, and stdlib date/time extensions. Jeremy Kemper

• Removed rarely-used DRb cache store. Jeremy Kemper

• TimeWithZone.name returns 'Time', to further thwart type checking Geoff Buesing

• Make TimeWithZone#to_formatted_s an alias to TimeWithZone#to_s #1796 Levin Alexander

• Introduce Array.wrap(foo) to wrap the argument in an array unless it's already an array. Wraps nil as an empty array. Use instead of Array(foo) and foo.to_a since they treat String as Enumerable. Jeremy Kemper

• TimeWithZone#xmlschema accepts optional fraction_digits argument [#1725 state:resolved] Nicholas Dainty

• Object#tap shim for Ruby < 1.8.7. Similar to Object#returning, tap yields self then returns self. Jeremy Kemper array.select { ... }.tap(&:inspect).map { ... }

• TimeWithZone#- gives correct result with wrapped DateTime, and with DateTime argument Geoff Buesing

• Fix Ruby's Time marshaling bug in pre-1.9 versions of Ruby: utc instances are now correctly unmarshaled with a utc zone instead of the system local zone [#900 state:resolved] Luca Guidi, Geoff Buesing

• Add Array#in_groups which splits or iterates over the array in specified number of groups. #579. [Adrian Mugnolo] Example:

  a = (1..10).to_a a.in_groups(3) # => 1, 2, 3, 4], [5, 6, 7, nil], [8, 9, 10, nil a.in_groups(3, false) # => 1, 2, 3, 4], [5, 6, 7], [8, 9, 10

  ActiveSupport::Inflector.inflections do |inflect| inflect.human(/_cnt$/i, '\1_count') end

  'jargon_cnt'.humanize # => 'Jargon count'

• TimeWithZone: when crossing DST boundary, treat Durations of days, months or years as variable-length, and all other values as absolute length. A time + 24.hours will advance exactly 24 hours, but a time + 1.day will advance 23-25 hours, depending on the day. Ensure consistent behavior across all advancing methods Geoff Buesing

• Added TimeZone #=~, to support matching zones by regex in time_zone_select. #195 Ernie Miller

2.1.0 (May 31st, 2008)

• TimeZone#to_s shows offset as GMT instead of UTC, because GMT will be more familiar to end users (see time zone selects used by Windows OS, google.com and yahoo.com.) Reverts [8370] Geoff Buesing

• Hash.from_xml: datetime xml types overflow to Ruby DateTime class when out of range of Time. Adding tests for utc offsets Geoff Buesing

• Remove unused JSON::RESERVED_WORDS, JSON.valid_identifier? and JSON.reserved_word? methods. Resolves #164. Cheah Chu Yeow

• Adding Date.current, which returns Time.zone.today if config.time_zone is set; otherwise returns Date.today Geoff Buesing

• TimeWithZone: date part getter methods (#year #mon #day etc) are defined on class; no longer relying on method_missing Geoff Buesing

• Time.zone.parse return nil for strings with no date information Geoff Buesing

• Time.zone.parse respects offset information in string. Resolves #105. Scott Fleckenstein, Geoff Buesing

• Added Ruby 1.8 implementation of Process.daemon

• Duration #since and #ago with no argument (e.g., 5.days.ago) return TimeWithZone when config.time_zone is set. Introducing Time.current, which returns Time.zone.now if config.time_zone is set, otherwise just returns Time.now Geoff Buesing

• Time#since behaves correctly when passed a Duration. Closes #11527 kemiller

• Add #getutc alias for DateTime#utc Geoff Buesing

• Refactor TimeWithZone: don't send #since, #ago, #+, #-, #advance through method_missing Geoff Buesing

• TZInfo: Removing unneeded TimezoneIndexDefinition, since we're not including Indexes::Timezones Geoff Buesing

• Removing unnecessary uses_tzinfo helper from tests, given that TZInfo is now bundled Geoff Buesing

• Bundling abbreviated version of TZInfo gem 0.3.8: only the classes and zone definitions required to support Rails time zone features are included. If a recent version of the full TZInfo gem is installed, this will take precedence over the bundled version Geoff Buesing

• TimeWithZone#marshal_load does zone lookup via Time.get_zone, so that tzinfo/Olson identifiers are handled Geoff Buesing

• Time.zone= accepts TZInfo::Timezone instances and Olson identifiers; wraps result in TimeZone instance Geoff Buesing

• Added Enumerable#sum for calculating a sum from the elements [David Heinemeier Hansson, jonathan@daikini.com]. Examples:

  [1, 2, 3].sum
  payments.sum { |p| p.price * p.tax_rate }
  payments.sum(&:price)
  

  This is instead of payments.inject(0) { |sum, p| sum + p.price }

• Correct and clarify Array#to_sentence docs. #5458 brad@madriska.com

• alias_method_chain preserves method punctuation so foo, foo?, and foo! may be chained with the same feature. Jeremy Kemper Example: 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 [nov@yo.rim.or.jp]. 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 [David Heinemeier Hansson]. Example:

  Hash.create_from_xml <<-EOT
    <note>
      <title>This is a note</title>
      <created-at type="date">2004-10-10</created-at>
    </note>
  EOT
  

  ...would return:

  { :note => { :title => "This is a note", :created_at => Date.new(2004, 10, 10) } }
  

• Added Jim Weirich's excellent FlexMock class to vendor (Copyright 2003, 2004 by Jim Weirich (jim@weriichhouse.org)) -- it's not automatically required, though, so require 'flexmock' is still necessary David Heinemeier Hansson

• Fixed that Module#alias_method_chain should work with both foo? foo! and foo at the same time #4954 anna@wota.jp

• 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 blair@orcaware.com

• Add OrderedHash#values. Sam Stephenson

• Added Array#to_s(:db) that'll produce a comma-separated list of ids [David Heinemeier Hansson]. 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. Michael Schoen

• 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
  end
  

  But this is just as easily done with:

  user_xml = adapters(:from => User, :to => Xml).each do
    break adapter.adapt(@user)
  end
  

• 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., guy.naor@famundo.com

• Document Module::delegate. #5002 pergesu@gmail.com

• Replace alias method chaining with Module#alias_method_chain. Marcel Molina Jr.

• Strip out punctuation on predicates or bang methods being aliased with alias_method_chain since target?_without_feature is not a valid method name. Add tests for 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. murphy@cYcnus.de

• Added Module#alias_method_chain Jamis Buck

• Updated to Builder 2.0 David Heinemeier Hansson

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

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" David Heinemeier Hansson

• 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. Michael Koziarski

• 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. Michael Koziarski

• Added Hash#to_xml and Array#to_xml that makes it much easier to produce XML from basic structures [David Heinemeier Hansson]. Examples:

  { :name => "David", :street_name => "Paulina", :age => 26, :moved_on => Date.new(2005, 11, 15) }.to_xml
  

  ...returns:

    <person>
      <street-name>Paulina</street-name>
      <name>David</name>
      <age type="integer">26</age>
      <moved-on type="date">2005-11-15</moved-on>
    </person>
  

• Moved Jim Weirich's wonderful Builder from Action Pack to Active Support (it's simply too useful to be stuck in AP) David Heinemeier Hansson

• Fixed that Array#to_sentence will return "" on an empty array instead of ", and" #3842, #4031 rubyonrails@beautifulpixel.com

• Add Enumerable#group_by for grouping collections based on the result of some block. Useful, for example, for grouping records by date.

  ex.

   latest_transcripts.group_by(&:day).each do |day, transcripts|
     p "#{day} -> #{transcripts.map(&:class) * ', '}"
   end
   "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 size.

  ex.

   %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 David Heinemeier Hansson

• 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 cohen.jeff@gmail.com

• Fix Object.subclasses_of to only return currently defined objects Jonathan Viney jonathan@bluewire.net.nz

• 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) [David Heinemeier Hansson]. Example:

  class Account < ActiveRecord::Base
    has_one :subscription
    delegate :free?, :paying?, :to => :subscription
    delegate :overdue?, :to => "subscription.last_payment"
  end
  
  account.free?    # => account.subscription.free?
  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
  end
  

  Reloading a class is done by removing its constant which will cause it to be loaded again on the next reference. David Heinemeier Hansson

• 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 Ken Miller

• 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 asnem@student.ethz.ch, JanPrill@blauton.de, 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' end end

• 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 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 keithm@infused.org

• 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 rails@jeffcole.net

• 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 timct@mac.com

• 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

• Replace '%e' from long and short time formats as Windows does not support it. #2344. Tom Ward tom@popdog.net

• Added to_s(:db) to Range, so you can get "BETWEEN '2005-12-10' AND '2005-12-12'" from Date.new(2005, 12, 10)..Date.new(2005, 12, 12) (and likewise with Times)

• Moved require_library_or_gem into Kernel. #1992 Michael Schuerig michael@schuerig.de

• 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 michael@schuerig.de

• 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

• Added Kernel#silence_warnings to turn off warnings temporarily for the passed block

• Added String#starts_with? and String#ends_with? #2118 Thijs van der Vossen

    inflect.plural /^(ox)$/i, '\1\2en'
    inflect.singular /^(ox)en/i, '\1'
  
    inflect.irregular 'octopus', 'octopi'
  
    inflect.uncountable "equipment"
  end
  

• 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 damn_pepe@gmail.com

• 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 paul@cnt.org

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 foamdino@gmail.com/others

• Fixed memory leak with Object#remove_subclasses_of, which inflicted a Rails application running in development mode with a ~20KB leak per request #1289 Chris McGrath

• 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 tuxie@dekadance.se

• Added an exception if calling id on nil to WhinyNil #584 kevin-temp@writesoon.com

• 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 jean.helou@gmail.com

• 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 Time#last_year to go back in time, not forward #1278 fabien@odilat.com

• Fixed the pluralization of analysis to analyses #1295 seattle@rootimage.msu.edu

• Fixed that Time.local(2005,12).months_since(1) would raise "ArgumentError: argument out of range" #1311 jhahn@niveon.com

• 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 Thijs van der Vossen

• 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'

    end
  end
  
  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 http://redhanded.hobix.com/inspect/objectBlank.html #783 _why the lucky stiff

• Added inflection rules for "sh" words, like "wish" and "fish" #755 phillip@pjbsoftware.com

• 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 Lütke

• 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 Time.now.tomorrow, Time.now.yesterday, Time.now.months_ago(4) #580 [DP|Flurin]. Examples:

  "Later today"         => now.in(3.hours),
  "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"           => now.in(1.year).change(:hour => 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
  end
  
  # Bar gets a clone of (not a reference to) Foo's attributes.
  class Bar < Foo
  end
  
  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 Jr.

• 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.
