## 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`
    from ruby's standard library.

    be able to set the day at which weeks are assumed to start.

*   Deprecated ActiveSupport::MessageEncryptor#encrypt and decrypt. *José Valim*

*   ActiveSupport::Notifications.subscribed provides subscriptions to events while a block runs. *fxn*

*   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*

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

*   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.
