     use Module#instance_methods from now on (which returns symbols). *fxn*

*    BufferedLogger is deprecated.  Use ActiveSupport::Logger, or the logger
     from Ruby stdlib.

*    Unicode database updated to 6.1.0.

*    Adds `encode_big_decimal_as_string` option to force JSON serialization of BigDecimals as numeric instead
     of wrapping them in strings for safety.

    now. *Jonathan Viney*

*   Fixes uninitialized constant `ActiveSupport::TaggedLogging::ERROR`. *kennyj*


## Rails 3.2.0 (January 20, 2012) ##

*   ActiveSupport::Base64 is deprecated in favor of ::Base64. *Sergey Nartimov*

*   Module#synchronize is deprecated with no replacement.  Please use `monitor`

*   Module#qualified_const_(defined?|get|set) are analogous to the corresponding methods
    in the standard API, but accept qualified constant names. *fxn*

*   Added inflection #deconstantize which complements #demodulize. This inflection
    removes the righmost segment in a qualified constant name. *fxn*

*   Added ActiveSupport:TaggedLogging that can wrap any standard Logger class to provide tagging capabilities *DHH*

        Logger = ActiveSupport::TaggedLogging.new(Logger.new(STDOUT))
        Logger.tagged("BCX") { Logger.info "Stuff" }                            # Logs "[BCX] Stuff"
        Logger.tagged("BCX", "Jason") { Logger.info "Stuff" }                   # Logs "[BCX] [Jason] Stuff"
        Logger.tagged("BCX") { Logger.tagged("Jason") { Logger.info "Stuff" } } # Logs "[BCX] [Jason] Stuff"

*   Added safe_constantize that constantizes a string but returns nil instead of an exception if the constant (or part of it) does not exist *Ryan Oblak*

*   Added Array#prepend as an alias for Array#unshift and Array#append as an alias for Array#<< *DHH*

*   The definition of blank string for Ruby 1.9 has been extended to Unicode whitespace.
    Also, in 1.8 the ideographic space U+3000 is considered to be whitespace. *Akira Matsuda, Damien Mathieu*

*   The inflector understands acronyms. *dlee*

*   Deprecated ActiveSupport::Memoizable in favor of Ruby memoization pattern *José Valim*

*   Added Time#all_day/week/quarter/year as a way of generating ranges (example: Event.where(created_at: Time.now.all_week)) *DHH*

*   Added instance_accessor: false as an option to Class#cattr_accessor and friends *DHH*

*   Removed ActiveSupport::SecureRandom in favor of SecureRandom from the standard library *Jon Leighton*

*   ActiveSupport::OrderedHash now has different behavior for #each and
    \#each_pair when given a block accepting its parameters with a splat. *Andrew Radev*

*   ActiveSupport::BufferedLogger#silence is deprecated.  If you want to squelch
    logs for a certain block, change the log level for that block.

*   ActiveSupport::BufferedLogger#open_log is deprecated.  This method should
    not have been public in the first place.

*   ActiveSupport::BufferedLogger's behavior of automatically creating the
    directory for your log file is deprecated.  Please make sure to create the
    directory for your log file before instantiating.

*   ActiveSupport::BufferedLogger#auto_flushing is deprecated.  Either set the
    sync level on the underlying file handle like this:

        f = File.open('foo.log', 'w')
        f.sync = true
        ActiveSupport::BufferedLogger.new f

    Or tune your filesystem.  The FS cache is now what controls flushing.

*   ActiveSupport::BufferedLogger#flush is deprecated.  Set sync on your
    filehandle, or tune your filesystem.


## Rails 3.1.4 (March 1, 2012) ##

*   No changes


## Rails 3.1.2 (November 18, 2011) ##

*   No changes


## Rails 3.1.1 (October 7, 2011) ##

*   ruby193: String#prepend is also unsafe *Akira Matsuda*

*   Fix obviously breakage of Time.=== for Time subclasses *jeremyevans*

*   Added fix so that file store does not raise an exception when cache dir does
    not exist yet. This can happen if a delete_matched is called before anything
    is saved in the cache. *Philippe Huibonhoa*

*   Fixed performance issue where TimeZone lookups would require tzinfo each time *Tim Lucas*

*   ActiveSupport::OrderedHash is now marked as extractable when using Array#extract_options! *Prem Sichanugrist*


## Rails 3.1.0 (August 30, 2011) ##

*   ActiveSupport::Dependencies#load and ActiveSupport::Dependencies#require now
    return the value from `super` *Aaron Patterson*

*   Fixed ActiveSupport::Gzip to work properly in Ruby 1.8 *Guillermo Iguaran*

*   Kernel.require_library_or_gem was deprecated and will be removed in Rails 3.2.0 *Josh Kalderimis*

*   ActiveSupport::Duration#duplicable? was fixed for Ruby 1.8 *thedarkone*

*   ActiveSupport::BufferedLogger set log encoding to BINARY, but still use text
    mode to output portable newlines. *fxn*

*   ActiveSupport::Dependencies now raises NameError if it finds an existing constant in load_missing_constant. This better reflects the nature of the error which is usually caused by calling constantize on a nested constant. *Andrew White*

*   Deprecated ActiveSupport::SecureRandom in favour of SecureRandom from the standard library *Jon Leighton*

*   New reporting method Kernel#quietly. *fxn*

*   Add String#inquiry as a convenience method for turning a string into a StringInquirer object *DHH*

*   Add Object#in? to test if an object is included in another object *Prem Sichanugrist, Brian Morearty, John Reitano*

*   LocalCache strategy is now a real middleware class, not an anonymous class
    posing for pictures.

*   ActiveSupport::Dependencies::ClassCache class has been introduced for
    holding references to reloadable classes.

*   ActiveSupport::Dependencies::Reference has been refactored to take direct
    advantage of the new ClassCache.

*   Backports Range#cover? as an alias for Range#include? in Ruby 1.8 *Diego Carrion, fxn*

*   Added weeks_ago and prev_week to Date/DateTime/Time. *Rob Zolkos, fxn*

*   Added before_remove_const callback to ActiveSupport::Dependencies.remove_unloadable_constants! *Andrew White*

*   JSON decoding now uses the multi_json gem which also vendors a json engine called OkJson. The yaml backend has been removed in favor of OkJson as a default engine for 1.8.x, while the built in 1.9.x json implementation will be used by default. *Josh Kalderimis*


## Rails 3.0.12 (March 1, 2012) ##

*   No changes.


## Rails 3.0.11 (November 18, 2011) ##

*   Added before_remove_const callback to ActiveSupport::Dependencies.remove_unloadable_constants! *Andrew White*


## Rails 3.0.1 (October 15, 2010) ##

*   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#since, #ago, #beginning_of_day, #end_of_day, and #xmlschema honor now the user time zone if set. *Geoff Buesing*

*   Extracted String#truncate from TextHelper#truncate *DHH*

*   Ruby 1.9: support UTF-8 case folding.  #4595 *Norman Clarke*

*   Removes Array#rand and backports Array#sample from Ruby 1.9, thanks to Marc-Andre Lafortune. *fxn*

*   Ruby 1.9: Renames last_(month|year) to prev_(month|year) in Date and Time. *fxn*

*   Aliases Date#sunday to Date#end_of_week. *fxn*

*   Backports Date#>> from 1.9 so that calculations do the right thing around the calendar reform. *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*

*   Time.local instances: Adding 24.hours across the DST boundary adds 24 hours instead of one day #2066 *Michael Curtis*


## 2.3.2 Final (March 15, 2009) ##

*   XmlMini supports LibXML and Nokogiri backends.  #2084, #2190 *Bart ten Brinke, Aaron Patterson*
        Example: XmlMini.backend = 'Nokogiri'

*   Vendorize i18n 0.1.3 gem (fixes issues with incompatible character encodings in Ruby 1.9) #2038 *Akira Matsuda*

*   Update bundled memcache-client from 1.5.0.5 to 1.6.4.99. See http://www.mikeperham.com/2009/02/15/memcache-client-performance/  *Mike Perham*

*   Ruby 1.9.1p0 fix: URI.unescape can decode multibyte chars.  #2033 *MOROHASHI Kyosuke*

*   Time#to_s(:rfc822) uses #formatted_offset instead of unreliable and non-standard %z directive #1899 *Zachary Zolton*

*   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*

*   Updated i18n gem to version 0.1.1 #1635 *Yaroslav Markin*

*   Add :allow_nil option to delegate. #1127 *Sergio Gil*

*   Add Benchmark.ms convenience method to benchmark realtime in milliseconds.  *Jeremy Kemper*

*   Updated included memcache-client to the 1.5.0.5 version which includes fixes from fiveruns and 37signals to deal with failover and timeouts #1535 *Joshua Sierles*

*   Multibyte: add multibyte-safe Chars#ord rather than falling back to String#ord.  #1483 *Jason Cheow*

*   I18n support for Array#to_sentence. Introduces support.array.words_connector, .two_words_connector, and .last_word_connector translation keys.  #1397 *Akira Matsuda*

*   Added ActiveSupport::OrderedHash#each_key and ActiveSupport::OrderedHash#each_value #1410 *Christoffer Sawicki*

*   Added ActiveSupport::MessageVerifier and MessageEncryptor to aid users who need to store signed and/or encrypted messages. *Michael Koziarski*

*   Added ActiveSupport::BacktraceCleaner to cut down on backtrace noise according to filters and silencers *David Heinemeier Hansson*

*   Added Object#try. ( Taken from http://ozmm.org/posts/try.html ) *Chris Wanstrath*

*   Added Enumerable#none? to check that none of the elements match the block #1408 *Damian Janowski*

*   TimeZone offset tests: use current_period, to ensure TimeZone#utc_offset is up-to-date *Geoff Buesing*

*   Update bundled TZInfo to 0.3.12 *Geoff Buesing*

*   Added lambda merging to OptionMerger (especially useful with named_scope and with_options) #726 *Paweł Kondzior*


## 2.2.1 RC2 (November 14th, 2008) ##

*   Increment the version of our altered memcache-client to prevent confusion caused when the 1.5.0 gem is installed.

*   Fixed the option merging in Array#to_xml #1126 *Rudolf Gavlas*

*   Make I18n::Backend::Simple reload its translations in development mode *David Heinemeier Hansson/Sven Fuchs*


## 2.2.0 RC1 (October 24th, 2008) ##

*   TimeWithZone#freeze: preload instance variables so that we can actually freeze *Geoff Buesing*

*   Fix Brasilia timezone #1180 *Marcus Derencius, Kane*

*   Time#advance recognizes fractional days and weeks. Deprecate Durations of fractional months and years #970 *Tom Lea*

*   Add ActiveSupport::Rescuable module abstracting ActionController::Base rescue_from features. *Norbert Crombach, Pratik Naik*

*   Switch from String#chars to String#mb_chars for the unicode proxy.  *Manfred Stienstra*

    This helps with 1.8.7 compatibility and also improves performance for some operations by reducing indirection.

*   TimeWithZone #wday, #yday and #to_date avoid trip through #method_missing *Geoff Buesing*

*   Added Time, Date, DateTime and TimeWithZone #past?, #future? and #today? #720 *Clemens Kofler, Geoff Buesing*

*   Fixed Sri Jayawardenepura time zone to map to Asia/Colombo *Jamis Buck*

*   Added Inflector#parameterize for easy slug generation ("Donald E. Knuth".parameterize => "donald-e-knuth") #713 *Matt Darby*

*   Changed cache benchmarking to be reported in milliseconds *David Heinemeier Hansson*

*   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]]

*   Fix TimeWithZone unmarshaling: coerce unmarshaled Time instances to utc, because Ruby's marshaling of Time instances doesn't respect the zone *Geoff Buesing*

*   Added Memoizable mixin for caching simple lazy loaded attributes *Josh Peek*

*   Move the test related core_ext stuff out of core_ext so it's only loaded by the test helpers.  *Michael Koziarski*

*   Add Inflection rules for String#humanize. #535 *Dan Manges*

    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*

*   Added Array#second through Array#fifth as aliases for Array#[1] through Array#[4] + Array#forty_two as alias for Array[41] *David Heinemeier Hansson*

*   Added test/do declaration style testing to ActiveSupport::TestCase *DHH via Jay Fields*

*   Added Object#present? which is equivalent to !Object#blank? *David Heinemeier Hansson*

*   Added Enumberable#many? to encapsulate collection.size > 1 *David Heinemeier Hansson/Damian Janowski*

*   Add more standard Hash methods to ActiveSupport::OrderedHash *Steve Purcell*

*   Namespace Inflector, Dependencies, OrderedOptions, and TimeZone under ActiveSupport *Josh Peek*

*   Added StringInquirer for doing things like StringInquirer.new("production").production? # => true and StringInquirer.new("production").development? # => false *David Heinemeier Hansson*

*   Fixed Date#end_of_quarter to not blow up on May 31st [#289 state:resolved] (Danger)


## 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*

*   TimeWithZone #+ and #- : ensure overflow to DateTime with Numeric arg *Geoff Buesing*

*   Time#to_json: don't convert to utc before encoding. References #175 *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*

*   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*

*   Adding TimeZone#parse *Geoff Buesing*

*   Adding TimeZone#at and DateTime#to_f *Geoff Buesing*

*   TimeWithZone responds to Ruby 1.9 weekday-named query methods *Geoff Buesing*

*   Time.=== returns true for TimeWithZone instances *Geoff Buesing*

*   TimeWithZone #+ and #- behave consistently with numeric arguments regardless of whether wrapped time is a Time or DateTime; consistenty answers false to #acts_like?(:date) *Geoff Buesing*

*   Add String#squish and String#squish! to remove consecutive chunks of whitespace.  #11123 *Jordi Bunster, Henrik N*

*   Serialize BigDecimals as Floats when using to_yaml. #8746 *Ernesto Jimenez*

*   Adding TimeWithZone #to_yaml, #to_datetime, #eql? and method aliases for duck-typing compatibility with Time *Geoff Buesing*

*   TimeZone#new method renamed #local; when used with Time.zone, constructor now reads: Time.zone.local() *Geoff Buesing*

*   Added Base64.encode64s to encode values in base64 without the newlines. This makes the values immediately usable as URL parameters or memcache keys without further processing *David Heinemeier Hansson*

*   Remove :nodoc: entries around the ActiveSupport test/unit assertions.  #10946 *dancroak, jamesh*

*   Add Time.zone_default accessor for setting the default time zone.  Rails::Configuration.time_zone sets this.  #10982 *Geoff Buesing*

*   Support retrieving TimeZones with a Duration.  TimeZone[-28800] == TimeZone[-480.minutes].  *Rick Olson*

*   TimeWithZone#- added, so that #- can handle a Time or TimeWithZone argument correctly *Geoff Buesing*

*   with_timezone test helper renamed with_env_tz, to distinguish between setting ENV['TZ'] and setting Time.zone in tests *Geoff Buesing*

*   Time#- coerces TimeWithZone argument to a Time instance so that difference in seconds can be calculated. Closes #10914 *Geoff Buesing, yyyc514*

*   Adding UTC zone to TimeZone; TimeWithZone no longer has to fake UTC zone with nil *Geoff Buesing*

*   Time.get_zone refactored to private method, given that the encapsulated logic is only useful internally *Geoff Buesing*

*   Time.zone uses thread-local variable for thread safety. Adding Time.use_zone, for overriding Time.zone locally inside a block. Removing unneeded Time.zone_reset! *Geoff Buesing*

*   TimeZone#to_s uses UTC rather than GMT; reapplying change that was undone in [8679]. #1689 *Cheah Chu Yeow*

*   Time.days_in_month defaults to current year if no year is supplied as argument #10799 [Radar], uses Date.gregorian_leap? to determine leap year, and uses constant lookup to determine days in month *Geoff Buesing*

*   Refactor Time and DateTime #to_formatted_s: use ternary instead of nested if/else *Geoff Buesing*

*   Adding Time and DateTime #formatted_offset, for outputting +HH:MM utc offset strings with cross-platform consistency *Geoff Buesing*

*   Adding alternate_utc_string option to TimeZone#formatted_offset. Removing unneeded TimeZone#offset. *Geoff Buesing*

*   Introduce ActiveSupport::TimeWithZone, for wrapping Time instances with a TimeZone. Introduce instance methods to Time for creating TimeWithZone instances, and class methods for managing a global time zone. *Geoff Buesing*

*   Replace non-dst-aware TimeZone class with dst-aware class from tzinfo_timezone plugin. TimeZone#adjust and #unadjust are no longer available; tzinfo gem must now be present in order to perform time zone calculations, via #local_to_utc and #utc_to_local methods. *Geoff Buesing*

*   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 *David Heinemeier Hansson*

*   Added parsing of file type in Hash.xml_in so you can easily do file uploads with base64 from an API *David Heinemeier Hansson*

        <person>
          <name>David</name>
          <avatar type="file" name="me.jpg" content_type="image/jpg">R0lGODlhkACZAPUAAM5lcfjrtMQCG=\n</avatar>
        </person>

        attributes = { :person => { :name => "David", :avatar => #<StringIO> } }
        attributes[:person][:avatar].content_type      # => "image/jpg"
        attributes[:person][:avatar].original_filename # => "me.jpg"
        attributes[:person][:avatar].read # => binary data of the file

*   Tighten rescue clauses.  #5985 *james@grayproductions.net*

*   Inflections: don't singularize -ies plurals.  *foamdino@gmail.com, Mark Van Holstyn*

*   Update Initializer to use load_once_paths to avoid plugin reloading. References #5852. *Nicholas Seckar*

*   Use Array#assoc in ActiveSupport::OrderedHash. *Mauricio Fernandez*

*   Greatly increased performance of String.to_json, which speeds up RJS considerably on large pages, fixes #3473 *Shugo Maeda*

*   Detect missing_constants calls from removed modules and fail accordingly. *Nicholas Seckar*

*   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*
        Example:
          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 *jon.evans@pobox.com*

*   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*
        # def foo()   @foo__rofl      end
        # def foo=(v) @foo__rofl = v  end
        self.attr_internal_naming_format = '@%s__rofl'
        attr_internal :foo

*   Raise fully qualified names upon name errors. #5533 *Lars Pind, Nicholas Seckar*

*   Add extention to obtain the missing constant from NameError instances. *Nicholas Seckar*

*   Thoroughly document inflections.  #5700 *petermichaux@gmail.com*

*   Added Module#alias_attribute [Jamis/David Heinemeier Hansson]. Example:

        class Content < ActiveRecord::Base
          # has a title attribute
        end

        class Email < ActiveRecord::Base
          alias_attribute :subject, :title
        end

        e = Email.find(1)
        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 = Proc.new { |message| raise message }

*   First cut of the Rails Deprecation system.   *Michael Koziarski*

*   Strip boolean XML content before checking for 'true' *Rick Olson*

*   Customize default BigDecimal formatting. References #5672 *Dave Thomas*

*   Correctly convert <foo nil="true"> to nil when using Hash.create_from_xml.  *Rick Olson*

*   Optional identity for Enumerable#sum defaults to zero. #5657 *gensym@mac.com*

*   HashWithIndifferentAccess shouldn't confuse false and nil. #5601 *Shugo Maeda*

*   Fixed HashWithIndifferentAccess#default #5586 *chris@seagul.co.uk*

*   More compatible Hash.create_from_xml. #5523 *nunemaker@gmail.com*

*   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*

*   Add Array#split for dividing arrays into one or more subarrays by value or block. *Sam Stephenson*

## 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" *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 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 *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*

*   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 *ikeda@dream.big.or.jp*

*   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 <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

*   Fixed memory leak with Active Record classes when Dependencies.mechanism = :load #1704 *Chris McGrath*

*   Fixed Inflector.underscore for use with acronyms, so HTML becomes html instead of htm_l #2173 *k@v2studio.com*

*   Fixed dependencies related infinite recursion bug when a controller file does not contain a controller class. Closes #1760. *rcolli2@tampabay.rr.com*

*   Fixed inflections for status, quiz, move #2056 *deirdre@deirdre.net*

*   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 *Manfred Stienstra*

*   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*

*   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"
        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*

*   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 *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*

*   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'
            values << 'baz'
          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*
