* Cache asset ids.  [Jeremy Kemper]

* Optimized named routes respect AbstractRequest.relative_url_root.  #9612 [danielmorrison, Jeremy Kemper]

* Introduce ActionController::Base.rescue_from to declare exception-handling methods. Cleaner style than the case-heavy rescue_action_in_public.  #9449 [Norbert Crombach]

* Rename some RequestForgeryProtection methods.  The class method is now #protect_from_forgery, and the default parameter is now 'authenticity_token'.  [Rick]

* Merge csrf_killer plugin into rails.  Adds RequestForgeryProtection model that verifies session-specific _tokens for non-GET requests.  [Rick]

* Secure #sanitize, #strip_tags, and #strip_links helpers against xss attacks.  Closes #8877. [Rick, Pratik Naik, Jacques Distler]

* Added FormHelper#label.  #8641, #9850 [jcoglan, jarkko]

* Added AtomFeedHelper (slightly improved from the atom_feed_helper plugin) [DHH]

* Prevent errors when generating routes for uncountable resources, (i.e. sheep where plural == singluar).   map.resources :sheep now creates sheep_index_url for the collection and sheep_url for the specific item.  [Koz]

* Added support for HTTP Only cookies (works in IE6+ and FF 2.0.5+) as an improvement for XSS attacks #8895 [Pratik Naik, Spakman]

* Don't warn when a path segment precedes a required segment. Closes #9615. [Nicholas Seckar]

* Fixed CaptureHelper#content_for to work with the optional content parameter instead of just the block #9434 [sandofsky/wildchild].

* Added Mime::Type.register_alias for dealing with different formats using the same mime type [DHH]. Example:

    class PostsController < ApplicationController
      before_filter :adjust_format_for_iphone

      def index
        @posts = Post.find(:all)
        
        respond_to do |format|
          format.html   # => renders index.html.erb and uses "text/html" as the content type
          format.iphone # => renders index.iphone.erb and uses "text/html" as the content type
        end
      end


      private
        def adjust_format_for_iphone
          if request.env["HTTP_USER_AGENT"] && request.env["HTTP_USER_AGENT"][/iPhone/]
            request.format = :iphone
          end
        end
    end

* Added that render :json will automatically call .to_json unless it's being passed a string [DHH].

* Autolink behaves well with emails embedded in URLs.  #7313 [Jeremy McAnally, Tarmo TÀnav]

* Fixed that default layouts did not take the format into account #9564 [Pratik Naik]

* Fixed optimized route segment escaping.  #9562 [wildchild, Jeremy Kemper]

* Added block acceptance to JavaScriptHelper#javascript_tag.  #7527 [Bob Silva, Tarmo TÀnav, rmm5t]

* root_path returns '/' not ''.  #9563 [Pratik Naik]

* Fixed that setting request.format should also affect respond_to blocks [DHH]

* Add option to force binary mode on tempfile used for fixture_file_upload.  #6380 [Jonathan Viney]

* Fixed that resource namespaces wouldn't stick to all nested resources #9399 [pixeltrix]

* Moved ActionController::Macros::AutoComplete into the auto_complete plugin on the official Rails svn.  #9512 [Pratik Naik]

* Moved ActionController::Macros::InPlaceEditing into the in_place_editor plugin on the official Rails svn.  #9513 [Pratik Naik]

* Removed deprecated form of calling xml_http_request/xhr without the first argument being the http verb [DHH]

* Removed deprecated methods [DHH]:

  - ActionController::Base#keep_flash (use flash.keep instead)
  - ActionController::Base#expire_matched_fragments (just call expire_fragment with a regular expression)
  - ActionController::Base.template_root/= methods (use ActionController#Base.view_paths/= instead)
  - ActionController::Base.cookie (use ActionController#Base.cookies[]= instead)

* Removed the deprecated behavior of appending ".png" to image_tag/image_path calls without an existing extension [DHH]

* Removed ActionController::Base.scaffold -- it went through the whole idea of scaffolding (card board walls you remove and tweak one by one). Use the scaffold generator instead (it does resources too now!) [DHH]

* Optimise named route generation when using positional arguments.  [Koz]

  This change delivers significant performance benefits for the most
  common usage scenarios for modern rails applications by avoiding the
  costly trip through url_for.  Initial benchmarks indicate this is
  between 6 and 20 times as fast.

* Explicitly require active_record/query_cache before using it.  [Jeremy Kemper]

* Fix layout overriding response status.  #9476 [lotswholetime]

* Fixed that file.content_type for uploaded files would include a trailing \r #9053 [bgreenlee]

* url_for now accepts a series of symbols representing the namespace of the record [Josh Knowles]

* Make :trailing_slash work with query parameters for url_for. Closes #4004 [nov]

* Make sure missing template exceptions actually say which template they were looking for.  Closes #8683 [dasil003]

* Fix errors with around_filters which do not yield, restore 1.1 behaviour with after filters. Closes #8891 [skaes]

  After filters will *no longer* be run if an around_filter fails to yield, users relying on
  this behaviour are advised to put the code in question after a yield statement in an around filter.
  

* Allow you to delete cookies with options. Closes #3685 [Josh Peek, Chris Wanstrath]

* Allow you to render views with periods in the name.  Closes #8076 [Norbert Crombach]

  render :partial => 'show.html.erb'

* Improve capture helper documentation.  #8796 [kampers]

* Prefix nested resource named routes with their action name, e.g. new_group_user_path(@group) instead of group_new_user_path(@group). The old nested action named route is deprecated in Rails 1.2.4.  #8558 [David Chelimsky]

* Allow sweepers to be created solely for expiring after controller actions, not model changes [DHH]

* Added assigns method to ActionController::Caching::Sweeper to easily access instance variables on the controller [DHH]

* Give the legacy X-POST_DATA_FORMAT header greater precedence during params parsing for backward compatibility.  [Jeremy Kemper]

* Fixed that link_to with an href of # when using :method will not allow for click-through without JavaScript #7037 [Steven Bristol, Josh Peek]

* Fixed that radio_button_tag should generate unique ids #3353 [Bob Silva, Rebecca, Josh Peek]

* Fixed that HTTP authentication should work if the header is called REDIRECT_X_HTTP_AUTHORIZATION as well #6754 [mislaw]

* Don't mistakenly interpret the request uri as the query string.  #8731 [Pratik Naik, Jeremy Kemper]

* Make ActionView#view_paths an attr_accessor for real this time.  Also, don't perform an unnecessary #compact on the @view_paths array in #initialize.  Closes #8582 [dasil003, julik, rick]

* Tolerate missing content type on multipart file uploads. Fix for Safari 3.  [Jeremy Kemper]

* Deprecation: remove pagination. Install the classic_pagination plugin for forward compatibility, or move to the superior will_paginate plugin.  #8157 [Josh Peek]

* Action caching is limited to GET requests returning 200 OK status.  #3335 [tom@craz8.com, halfbyte, Dan Kubb, Josh Peek]

* Improve Text Helper test coverage.  #7274 [Rob Sanheim, Josh Peek]

* Improve helper test coverage.  #7208, #7212, #7215, #7233, #7234, #7235, #7236, #7237, #7238, #7241, #7243, #7244 [Rich Collins, Josh Peek]

* Improve UrlRewriter tests.  #7207 [Rich Collins]

* Resources: url_for([parent, child]) generates /parents/1/children/2 for the nested resource. Likewise with the other simply helpful methods like form_for and link_to.  #6432 [mhw, Jonathan Vaught, lotswholetime]

* Assume html format when rendering partials in RJS. #8076 [Rick]

* Don't double-escape url_for in views.  #8144 [Rich Collins, Josh Peek]

* Allow JSON-style values for the :with option of observe_field.  Closes #8557 [kommen]

* Remove RAILS_ROOT from backtrace paths.  #8540 [Tim Pope]

* Routing: map.resource :logo routes to LogosController so the controller may be reused for multiple nestings or namespaces.  [Jeremy Kemper]

* render :partial recognizes Active Record associations as Arrays.  #8538 [Kamal Fariz Mahyuddin]

* Routing: drop semicolon and comma as route separators.  [Jeremy Kemper]

* request.remote_ip understands X-Forwarded-For addresses with nonstandard whitespace.  #7386 [moses]

* Don't prepare response when rendering a component.  #8493 [jsierles]

* Reduce file stat calls when checking for template changes.  #7736 [alex]

* Added custom path cache_page/expire_page parameters in addition to the options hashes [DHH]. Example:

    def index
      caches_page(response.body, "/index.html")
    end

* Action Caching speedup.  #8231 [skaes]

* Wordsmith resources documentation.  #8484 [marclove]

* Added option to suppress :size when using :maxlength for FormTagHelper#text_field #3112 [Tim Pope]

* catch possible WSOD when trying to render a missing partial. Closes #8454 [Catfish]

* Rewind request body after reading it, if possible.  #8438 [s450r1]

* Resource namespaces are inherited by their has_many subresources.  #8280 [marclove, ggarside]

* Fix filtered parameter logging with nil parameter values.  #8422 [choonkeat]

* Integration tests: alias xhr to xml_http_request and add a request_method argument instead of always using POST.  #7124 [Nik Wakelin, Francois Beausoleil, Wizard]

* Document caches_action.  #5419 [Jarkko Laine]

* Update to Prototype 1.5.1.  [Sam Stephenson]

* Allow routes to be decalred under namespaces [Tobias Luetke]: 
  
  map.namespace :admin do |admin|
    admin.root :controller => "products"       
    admin.feed 'feed.xml', :controller => 'products', :action => 'feed', :format => 'xml'
  end
  
* Update to script.aculo.us 1.7.1_beta3.  [Thomas Fuchs]

* observe_form always sends the serialized form.  #5271 [manfred, normelton@gmail.com]

* Parse url-encoded and multipart requests ourselves instead of delegating to CGI.  [Jeremy Kemper]

* select :include_blank option can be set to a string instead of true, which just uses an empty string.  #7664 [Wizard]

* Added url_for usage on render :location, which allows for record identification [DHH]. Example:

    render :xml => person, :status => :created, :location => person
  
  ...expands the location to person_url(person).

* Introduce the request.body stream. Lazy-read to parse parameters rather than always setting RAW_POST_DATA. Reduces the memory footprint of large binary PUT requests.  [Jeremy Kemper]

* Add some performance enhancements to ActionView.

  * Cache base_paths in @@cached_base_paths
  * Cache template extensions in @@cached_template_extension
  * Remove unnecessary rescues

* Assume that rendered partials go by the HTML format by default

  def my_partial
    render :update do |page|
      # in this order
      # _foo.html.erb
      # _foo.erb
      # _foo.rhtml
      page.replace :foo, :partial => 'foo'
    end
  end

* Added record identifications to FormHelper#form_for and PrototypeHelper#remote_form_for [DHH]. Examples:

    <% form_for(@post) do |f| %>
      ...
    <% end %>
  
  This will expand to be the same as:
  
    <% form_for :post, @post, :url => post_path(@post), :html => { :method => :put, :class => "edit_post", :id => "edit_post_45" } do |f| %>
      ...
    <% end %>
  
  And for new records:
  
    <% form_for(Post.new) do |f| %>
      ...
    <% end %>
  
  This will expand to be the same as:
  
    <% form_for :post, @post, :url => posts_path, :html => { :class => "new_post", :id => "new_post" } do |f| %>
      ...
    <% end %>

* Rationalize route path escaping according to RFC 2396 section 3.3.  #7544, #8307. [Jeremy Kemper, chrisroos, begemot, jugend]

* Added record identification with polymorphic routes for ActionController::Base#url_for and ActionView::Base#url_for [DHH]. Examples:

    redirect_to(post)         # => redirect_to(posts_url(post))         => Location: http://example.com/posts/1
    link_to(post.title, post) # => link_to(post.title, posts_url(post)) => <a href="/posts/1">Hello world</a>

  Any method that calls url_for on its parameters will automatically benefit from this. 

* Removed deprecated parameters_for_method_reference concept (legacy from before named routes) [DHH]

* Add ActionController::Routing::Helpers, a module to contain common URL helpers such as polymorphic_url. [Nicholas Seckar]

* Included the HttpAuthentication plugin as part of core (ActionController::HttpAuthentication::Basic) [DHH]

* Modernize documentation for form helpers. [jeremymcanally]

* Add brief introduction to REST to the resources documentation. [fearoffish]

* Fix various documentation typos throughout ActionPack. [Henrik N]

* Enhance documentation and add examples for url_for. [jeremymcanally]

* Fix documentation typo in routes. [Norbert Crombach, pam]

* Sweep flash when filter chain is halted. [Caio Chassot <lists@v2studio.com>]

* Fixed that content_tag with a block will just return the result instead of concate it if not used in a ERb view #7857, #7432 [michael.niessner]

* Replace the current block/continuation filter chain handling by an implementation based on a simple loop.  #8226 [Stefan Kaes]

* Update UrlWriter to accept :anchor parameter. Closes #6771. [octopod]

* Added RecordTagHelper for using RecordIdentifier conventions on divs and other container elements [DHH]. Example:

    <% div_for(post) do %>     <div id="post_45" class="post">
      <%= post.body %>           What a wonderful world!
    <% end %>                  </div>

* Added page[record] accessor to JavaScriptGenerator that relies on RecordIdentifier to find the right dom id [DHH]. Example:

    format.js do
      # Calls: new Effect.fade('post_45');
      render(:update) { |page| page[post].visual_effect(:fade) }
    end

* Added RecordIdentifier to enforce view conventions on records for dom ids, classes, and partial paths [DHH]

* Added map.namespace to deal with the common situation of admin sections and the like [DHH]

    Before:
    
      map.resources :products, :path_prefix => "admin", :controller => "admin/products", :collection => { :inventory => :get }, :member => { :duplicate => :post }
      map.resources :tags, :name_prefix => 'admin_product_', :path_prefix => "admin/products/:product_id", :controller => "admin/product_tags"
      map.resources :images, :name_prefix => 'admin_product_', :path_prefix => "admin/products/:product_id", :controller => "admin/product_images"
      map.resources :variants, :name_prefix => 'admin_product_', :path_prefix => "admin/products/:product_id", :controller => "admin/product_variants"

    After:
    
      map.namespace(:admin) do |admin|
        admin.resources :products,
          :collection => { :inventory => :get },
          :member     => { :duplicate => :post },
          :has_many   => [ :tags, :images, :variants ]
      end

* Added :name_prefix as standard for nested resources [DHH]. WARNING: May be backwards incompatible with your app

    Before:

      map.resources :emails do |emails|
        emails.resources :comments,    :name_prefix => "email_"
        emails.resources :attachments, :name_prefix => "email_"
      end
      
    After:

      map.resources :emails do |emails|
        emails.resources :comments
        emails.resources :attachments
      end
    
    This does mean that if you intended to have comments_url go to /emails/5/comments, then you'll have to set :name_prefix to nil explicitly.

* Added :has_many and :has_one for declaring plural and singular resources beneath the current [DHH]

    Before:
      
      map.resources :notes do |notes|
        notes.resources :comments
        notes.resources :attachments
        notes.resource :author
      end
    
    After:
    
      map.resources :notes, :has_many => [ :comments, :attachments ], :has_one => :author

* Added that render :xml will try to call to_xml if it can [DHH]. Makes these work:

    render :xml => post
    render :xml => comments

* Added :location option to render so that the common pattern of rendering a response after creating a new resource is now a 1-liner [DHH]

    render :xml => post.to_xml, :status => :created, :location => post_url(post)

* Ensure that render_text only adds string content to the body of the response [DHH]

* Return the string representation from an Xml Builder when rendering a partial. Closes #5044 [Tim Pope]

* Fixed that parameters from XML should also be presented in a hash with indifferent access [DHH]

* Tweak template format rules so that the ACCEPT header is only used if it's text/javascript.  This is so ajax actions without a :format param get recognized as Mime::JS. [Rick]

* The default respond_to blocks don't set a specific extension anymore, so that both 'show.rjs' and 'show.js.rjs' will work. [Rick]

* Allow layouts with extension of .html.erb.  Closes #8032 [Josh Knowles]

* Change default respond_to templates for xml and rjs formats. [Rick]

  * Default xml template goes from #{action_name}.rxml => #{action_name}.xml.builder.
  * Default rjs template goes from #{action_name}.rjs => #{action_name}.js.rjs.
  
  You can still specify your old templates:
  
    respond_to do |format|
      format.xml do
        render :action => "#{action_name}.rxml"
      end
    end

* Fix WSOD due to modification of a formatted template extension so that requests to templates like 'foo.html.erb' fail on the second hit.  [Rick]

* Fix WSOD when template compilation fails [Rick]

* Change ActionView template defaults.  Look for templates using the request format first, such as "show.html.erb" or "show.xml.builder", before looking for the old defaults like "show.erb" or "show.builder" [Rick]

* Highlight helper highlights one or many terms in a single pass.  [Jeremy Kemper]

* Dropped the use of ; as a separator of non-crud actions on resources and went back to the vanilla slash. It was a neat idea, but lots of the non-crud actions turned out not to be RPC (as the ; was primarily intended to discourage), but legitimate sub-resources, like /parties/recent, which didn't deserve the uglification of /parties;recent. Further more, the semicolon caused issues with caching and HTTP authentication in Safari. Just Not Worth It [DHH]

* Added that FormTagHelper#submit_tag will return to its original state if the submit fails and you're using :disable_with [DHH]

* Cleaned up, corrected, and mildly expanded ActionPack documentation.  Closes #7190 [jeremymcanally]

* Small collection of ActionController documentation cleanups.  Closes #7319 [jeremymcanally]

* Make sure the route expiry hash is constructed by comparing the to_param-ized values of each hash. [Jamis Buck]

* Allow configuration of the default action cache path for #caches_action calls.  [Rick Olson]

  class ListsController < ApplicationController
    caches_action :index, :cache_path => Proc.new { |controller| 
      controller.params[:user_id] ? 
        controller.send(:user_lists_url, c.params[:user_id]) :
        controller.send(:lists_url) }
  end

* Performance: patch cgi/session/pstore to require digest/md5 once rather than per #initialize.  #7583 [Stefan Kaes]

* Cookie session store: ensure that new sessions doesn't reuse data from a deleted session in the same request.  [Jeremy Kemper]

* Deprecation: verification with :redirect_to => :named_route shouldn't be deprecated.  #7525 [Justin French]

* Cookie session store: raise ArgumentError when :session_key is blank.  [Jeremy Kemper]

* Deprecation: remove deprecated request, redirect, and dependency methods. Remove deprecated instance variables. Remove deprecated url_for(:symbol, *args) and redirect_to(:symbol, *args) in favor of named routes. Remove uses_component_template_root for toplevel components directory. Privatize deprecated render_partial and render_partial_collection view methods. Remove deprecated link_to_image, link_image_to, update_element_function, start_form_tag, and end_form_tag helper methods. Remove deprecated human_size helper alias.  [Jeremy Kemper]

* Consistent public/protected/private visibility for chained methods.  #7813 [Dan Manges]

* Prefer MIME constants to strings.  #7707 [Dan Kubb]

* Allow array and hash query parameters. Array route parameters are converted/to/a/path as before.  #6765, #7047, #7462 [bgipsy, Jeremy McAnally, Dan Kubb, brendan]

# Add a #dbman attr_reader for CGI::Session and make CGI::Session::CookieStore#generate_digest public so it's easy to generate digests
using the cookie store's secret. [Rick]

* Added Request#url that returns the complete URL used for the request [DHH]

* Extract dynamic scaffolding into a plugin.  #7700 [Josh Peek]

* Added user/password options for url_for to add http authentication in a URL [DHH]

* Fixed that FormTagHelper#text_area_tag should disregard :size option if it's not a string [Brendon Davidson]

* Set the original button value in an attribute of the button when using the :disable_with key with submit_tag, so that the original can be restored later. [Jamis Buck]

* session_enabled? works with session :off.  #6680 [Catfish]

* Added :port and :host handling to UrlRewriter (which unified url_for usage, regardless of whether it's called in view or controller) #7616 [alancfrancis]

* Allow send_file/send_data to use a registered mime type as the :type parameter #7620 [jonathan]

* Allow routing requirements on map.resource(s) #7633 [quixoten]. Example:

  map.resources :network_interfaces, :requirements => { :id => /^\d+\.\d+\.\d+\.\d+$/ }

* Cookie session store: empty and unchanged sessions don't write a cookie.  [Jeremy Kemper]

* Added helper(:all) as a way to include all helpers from app/helpers/**/*.rb in ApplicationController [DHH]

* Integration tests: introduce methods for other HTTP methods.  #6353 [caboose]

* Routing: better support for escaped values in route segments.  #7544 [Chris
Roos]

* Introduce a cookie-based session store as the Rails default. Sessions typically contain at most a user_id and flash message; both fit within the 4K cookie size limit. A secure message digest is included with the cookie to ensure data integrity (a user cannot alter his user_id without knowing the secret key included in the digest). If you have more than 4K of session data or don't want your data to be visible to the user, pick another session store.  Cookie-based sessions are dramatically faster than the alternatives.   [Jeremy Kemper]

  Example config/environment.rb:
    # Use an application-wide secret key and the default SHA1 message digest.
    config.action_controller.session = { :secret => "can't touch this" }

    # Store a secret key per user and employ a stronger message digest.
    config.action_controller.session = {
      :digest => 'SHA512',
      :secret => Proc.new { User.current.secret_key }
    }

* Added .erb and .builder as preferred aliases to the now deprecated .rhtml and .rxml extensions [Chad Fowler]. This is done to separate the renderer from the mime type. .erb templates are often used to render emails, atom, csv, whatever. So labeling them .rhtml doesn't make too much sense. The same goes for .rxml, which can be used to build everything from HTML to Atom to whatever. .rhtml and .rxml will continue to work until Rails 3.0, though. So this is a slow phasing out. All generators and examples will start using the new aliases, though.

* Added caching option to AssetTagHelper#stylesheet_link_tag and AssetTagHelper#javascript_include_tag [DHH]. Examples:

    stylesheet_link_tag :all, :cache => true # when ActionController::Base.perform_caching is false =>
      <link href="/stylesheets/style1.css"  media="screen" rel="Stylesheet" type="text/css" />
      <link href="/stylesheets/styleB.css"  media="screen" rel="Stylesheet" type="text/css" />
      <link href="/stylesheets/styleX2.css" media="screen" rel="Stylesheet" type="text/css" />
 
    stylesheet_link_tag :all, :cache => true # when ActionController::Base.perform_caching is true =>
      <link href="/stylesheets/all.css"  media="screen" rel="Stylesheet" type="text/css" />

  ...when caching is on, all.css is the concatenation of style1.css, styleB.css, and styleX2.css.
  Same deal for JavaScripts.

* Work around the two connection per host browser limit: use asset%d.myapp.com to distribute asset requests among asset[0123].myapp.com. Use a DNS wildcard or CNAMEs to map these hosts to your asset server. See http://www.die.net/musings/page_load_time/ for background.  [Jeremy Kemper]

* Added default mime type for CSS (Mime::CSS) [DHH]

* Added that rendering will automatically insert the etag header on 200 OK responses. The etag is calculated using MD5 of the response body. If a request comes in that has a matching etag, the response will be changed to a 304 Not Modified and the response body will be set to an empty string. [DHH]

* Added X-Runtime to all responses with the request run time [DHH]

* Add Mime::Type convenience methods to check the current mime type. [Rick]

  request.format.html? # => true if Mime::HTML
  request.format.jpg?  # => true if Mime::JPG

  # ActionController sample usage:
  # the session will be disabled for non html/ajax requests
  session :off, :if => Proc.new { |req| !(req.format.html? || req.format.js?) }

* Performance: patch cgi/session to require digest/md5 once rather than per #create_new_id.  [Stefan Kaes]

* Add a :url_based_filename => true option to ActionController::Streaming::send_file, which allows URL-based filenames.  [Thomas Fuchs]

* Fix that FormTagHelper#submit_tag using :disable_with should trigger the onsubmit handler of its form if available [DHH]

* Fix #render_file so that TemplateError is called with the correct params and you don't get the WSOD.  [Rick]

* Fix issue with deprecation messing up #template_root= usage.  Add #prepend_view_path and #append_view_path to allow modification of a copy of the
superclass' view_paths.  [Rick]

* Allow Controllers to have multiple view_paths instead of a single template_root.  Closes #2754 [John Long]

* Add much-needed html-scanner tests.  Fixed CDATA parsing bug. [Rick]

* improve error message for Routing for named routes.  Closes #7346 [Rob Sanheim]

* Added enhanced docs to routing assertions.  Closes #7359 [Rob Sanheim]

* fix form_for example in ActionController::Resources documentation.  Closes #7362 [gnarg]

* Make sure that the string returned by TextHelper#truncate is actually a string, not a char proxy -- that should only be used internally while working on a multibyte-safe way of truncating [DHH]

* Added FormBuilder#submit as a delegate for FormTagHelper#submit_tag [DHH]

* Allow Routes to generate all urls for a set of options by specifying :generate_all => true. Allows caching to properly set or expire all paths for a resource. References #1739. [Nicholas Seckar]

* Change the query parser to map empty GET params to "" rather than nil. Closes #5694. [Nicholas Seckar]

* date_select and datetime_select take a :default option.  #7052 [nik.wakelin]
    date_select "post", "written_on", :default => 3.days.from_now
    date_select "credit_card", "bill_due", :default => { :day => 20 }

* select :multiple => true suffixes the attribute name with [] unless already suffixed.  #6977 [nik.kakelin, ben, julik]

* Improve routes documentation.  #7095 [zackchandler]

* mail_to :encode => 'hex' also encodes the mailto: part of the href attribute as well as the linked email when no name is given.  #2061 [Jarkko Laine, pfc.pille@gmx.net]

* Resource member routes require :id, eliminating the ambiguous overlap with collection routes.  #7229 [dkubb]

* Remove deprecated assertions.  [Jeremy Kemper]

* Change session restoration to allow namespaced models to be autoloaded. Closes #6348. [Nicholas Seckar]

* Fix doubly appearing parameters due to string and symbol mixups. Closes #2551. [aeden]

* Fix overly greedy rescues when loading helpers. Fixes #6268. [Nicholas Seckar]

* Fixed NumberHelper#number_with_delimiter to use "." always for splitting the original number, not the delimiter parameter #7389 [ceefour]

* Autolinking recognizes trailing and embedded . , : ;  #7354 [Jarkko Laine]

* Make TextHelper::auto_link recognize URLs with colons in path correctly, fixes #7268.  [imajes]

* Update to script.aculo.us 1.7.0.  [Thomas Fuchs]

* Modernize cookie testing code, and increase coverage (Heckle++) #7101 [Kevin Clark]

* Improve Test Coverage for ActionController::Routing::Route#matches_controller_and_action? (Heckle++) #7115 [Kevin Clark]

* Heckling ActionController::Resources::Resource revealed that set_prefixes didn't break when :name_prefix was munged. #7081 [Kevin Clark]

* Fix #distance_of_time_in_words to report accurately against the Duration class.  #7114 [eventualbuddha]

* Refactor #form_tag to allow easy extending.  [Rick]

* Update to Prototype 1.5.0. [Sam Stephenson]

* RecordInvalid, RecordNotSaved => 422 Unprocessable Entity, StaleObjectError => 409 Conflict.  #7097 [dkubb]

* Allow fields_for to be nested inside form_for, so that the name and id get properly constructed [Jamis Buck]

* Allow inGroupsOf and eachSlice to be called through rjs. #7046 [Cody Fauser]

* Allow exempt_from_layout :rhtml.  #6742, #7026 [Dan Manges, Squeegy]

* Recognize the .txt extension as Mime::TEXT [Rick]

* Fix parsing of array[] CGI parameters so extra empty values aren't included.  #6252 [Nicholas Seckar, aiwilliams, brentrowland]

* link_to_unless_current works with full URLs as well as paths.  #6891 [Jarkko Laine, manfred, idrifter]

* Lookup the mime type for #auto_discovery_link_tag in the Mime::Type class.  Closes #6941 [Josh Peek]

* Fix bug where nested resources ignore a parent singleton parent's path prefix.  Closes #6940 [Dan Kubb]

* Fix no method error with error_messages_on.  Closes #6935 [nik.wakelin Koz]

* Slight doc tweak to the ActionView::Helpers::PrototypeHelper#replace docs.  Closes #6922 [Steven Bristol]

* Slight doc tweak to #prepend_filter.  Closes #6493 [Jeremy Voorhis]

* Add more extensive documentation to the AssetTagHelper.  Closes #6452 [Bob Silva]

* Clean up multiple calls to #stringify_keys in TagHelper, add better documentation and testing for TagHelper.  Closes #6394 [Bob Silva]

* [DOCS] fix reference to ActionController::Macros::AutoComplete for #text_field_with_auto_complete. Closes #2578 [Jan Prill]

* Make sure html_document is reset between integration test requests. [ctm]

* Set session to an empty hash if :new_session => false and no session cookie or param is present. CGI::Session was raising an unrescued ArgumentError.  [Josh Susser]

* Routing uses URI escaping for path components and CGI escaping for query parameters.  [darix, Jeremy Kemper]

* Fix assert_redirected_to bug where redirecting from a nested to to a top-level controller incorrectly added the current controller's nesting.  Closes #6128.  [Rick Olson]

* Singleton resources: POST /singleton => create, GET /singleton/new => new.  [Jeremy Kemper]

* Use 400 Bad Request status for unrescued ActiveRecord::RecordInvalid exceptions.  [Jeremy Kemper]

* Silence log_error deprecation warnings from inspecting deprecated instance variables.  [Nate Wiger]

* Fix HTML::Node to output double quotes instead of single quotes.  Closes #6845 [mitreandy]

* Correctly report which filter halted the chain.  #6699 [Martin Emde]

* Fix a bug in Routing where a parameter taken from the path of the current request could not be used as a query parameter for the next. Closes #6752. [Nicholas Seckar]

* Unrescued ActiveRecord::RecordNotFound responds with 404 instead of 500.  [Jeremy Kemper]

* Improved auto_link to match more valid urls correctly [Tobias Luetke]

* Add singleton resources. [Rick Olson]

  map.resource :account
  
  GET /account
  GET /account;edit
  UPDATE /account
  DELETE /account

* respond_to recognizes JSON. render :json => @person.to_json automatically sets the content type and takes a :callback option to specify a client-side function to call using the rendered JSON as an argument.  #4185 [Scott Raymond, eventualbuddha]
    # application/json response with body 'Element.show({:name: "David"})'
    respond_to do |format|
      format.json { render :json => { :name => "David" }.to_json, :callback => 'Element.show' }
    end

* Makes :discard_year work without breaking multi-attribute parsing in AR.  #1260, #3800 [sean@ardismg.com, jmartin@desertflood.com, stephen@touset.org, Bob Silva]

* Adds html id attribute to date helper elements.  #1050, #1382 [mortonda@dgrmm.net, David North, Bob Silva]

* Add :index and @auto_index capability to model driven date/time selects.  #847, #2655 [moriq, Doug Fales, Bob Silva]

* Add :order to datetime_select, select_datetime, and select_date.  #1427 [Timothee Peignier, patrick@lenz.sh, Bob Silva]

* Added time_select to work with time values in models. Update scaffolding.  #2489, #2833 [Justin Palmer, Andre Caum, Bob Silva]

* Added :include_seconds to select_datetime, datetime_select and time_select.  #2998 [csn, Bob Silva]

* All date/datetime selects can now accept an array of month names with :use_month_names. Allows for localization.  #363 [tomasj, Bob Silva]

* Adds :time_separator to select_time and :date_separator to select_datetime. Preserves BC.  #3811 [Bob Silva]

* Added map.root as an alias for map.connect '' [DHH]

* Added Request#format to return the format used for the request as a mime type. If no format is specified, the first Request#accepts type is used. This means you can stop using respond_to for anything else than responses [DHH]. Examples:

    GET /posts/5.xml   | request.format => Mime::XML
    GET /posts/5.xhtml | request.format => Mime::HTML
    GET /posts/5       | request.format => request.accepts.first (usually Mime::HTML for browsers)

* Added the option for extension aliases to mime type registration [DHH]. Example (already in the default routes):

    Mime::Type.register "text/html", :html, %w( application/xhtml+xml ), %w( xhtml )
  
  ...will respond on both .html and .xhtml.

* @response.redirect_url works with 201 Created responses: just return headers['Location'] rather than checking the response status.  [Jeremy Kemper]

* Added CSV to Mime::SET so that respond_to csv will work [Cody Fauser]

* Fixed that HEAD should return the proper Content-Length header (that is, actually use @body.size, not just 0) [DHH]

* Added GET-masquarading for HEAD, so request.method will return :get even for HEADs. This will help anyone relying on case request.method to automatically work with HEAD and map.resources will also allow HEADs to all GET actions. Rails automatically throws away the response content in a reply to HEAD, so you don't even need to worry about that. If you, for whatever reason, still need to distinguish between GET and HEAD in some edge case, you can use Request#head? and even Request.headers["REQUEST_METHOD"] for get the "real" answer. Closes #6694 [DHH]

* Update Routing to complain when :controller is not specified by a route. Closes #6669. [Nicholas Seckar]

* Ensure render_to_string cleans up after itself when an exception is raised.  #6658 [Rob Sanheim]

* Extract template_changed_since? from compile_template? so plugins may override its behavior for non-file-based templates.  #6651 [Jeff Barczewski]

* Update to Prototype and script.aculo.us [5579]. [Thomas Fuchs]

* simple_format helper doesn't choke on nil.  #6644 [jerry426]

* Update to Prototype 1.5.0_rc2 [5550] which makes it work in Opera again [Thomas Fuchs]

* Reuse named route helper module between Routing reloads. Use remove_method to delete named route methods after each load. Since the module is never collected, this fixes a significant memory leak. [Nicholas Seckar]

* ActionView::Base.erb_variable accessor names the buffer variable used to render templates. Defaults to _erbout; use _buf for erubis.  [Rick Olson]

* assert_select_rjs :remove.  [Dylan Egan]

* Always clear model associations from session.  #4795 [sd@notso.net, andylien@gmail.com]

* Update to Prototype 1.5.0_rc2. [Sam Stephenson]

* Remove JavaScriptLiteral in favor of ActiveSupport::JSON::Variable. [Sam Stephenson]

* Sync ActionController::StatusCodes::STATUS_CODES with http://www.iana.org/assignments/http-status-codes.  #6586 [dkubb]

* Multipart form values may have a content type without being treated as uploaded files if they do not provide a filename.  #6401 [Andreas Schwarz, Jeremy Kemper]

* assert_response supports symbolic status codes.  #6569 [Kevin Clark]
    assert_response :ok
    assert_response :not_found
    assert_response :forbidden

* Cache parsed query parameters.  #6559 [Stefan Kaes]

* Deprecate JavaScriptHelper#update_element_function, which is superseeded by RJS [Thomas Fuchs]

* pluralize helper interprets nil as zero.  #6474 [Tim Pope]

* Fix invalid test fixture exposed by stricter Ruby 1.8.5 multipart parsing.  #6524 [Bob Silva]

* Set ActionView::Base.default_form_builder once rather than passing the :builder option to every form or overriding the form helper methods.  [Jeremy Kemper]

* Deprecate expire_matched_fragments. Use expire_fragment instead.  #6535 [Bob Silva]

* Update to latest Prototype, which doesn't serialize disabled form elements, adds clone() to arrays, empty/non-string Element.update() and adds a fixes excessive error reporting in WebKit beta versions [Thomas Fuchs]

* Deprecate start_form_tag and end_form_tag.  Use form_tag / '</form>' from now on.  [Rick]

* Added block-usage to PrototypeHelper#form_remote_tag, document block-usage of FormTagHelper#form_tag [Rick]

* Add a 0 margin/padding div around the hidden _method input tag that form_tag outputs.  [Rick]

* Added block-usage to TagHelper#content_tag [DHH]. Example:

   <% content_tag :div, :class => "strong" %>
     Hello world!
   <% end %>
  
  Will output:
    <div class="strong">Hello world!</div>

* Deprecated UrlHelper#link_to_image and UrlHelper#link_to :post => true #6409 [BobSilva]

* Upgraded NumberHelper with number_to_phone support international formats to comply with ITU E.123 by supporting area codes with less than 3 digits, added precision argument to number_to_human_size (defaults to 1) #6421 [BobSilva]

* Fixed that setting RAILS_ASSET_ID to "" should not add a trailing slash after assets #6454 [BobSilva/chrismear]

* Force *_url named routes to show the host in ActionView [Rick]

  <%= url_for ... %> # no host
  <%= foo_path %>    # no host
  <%= foo_url %>     # host!

* Add support for converting blocks into function arguments to JavaScriptGenerator#call and JavaScriptProxy#call. [Sam Stephenson]

* Add JavaScriptGenerator#literal for wrapping a string in an object whose #to_json is the string itself. [Sam Stephenson]

* Add <%= escape_once html %> to escape html while leaving any currently escaped entities alone.  Fix button_to double-escaping issue. [Rick]

* Fix double-escaped entities, such as &amp;amp;, &amp;#123;, etc. [Rick]

* Fix deprecation warnings when rendering the template error template. [Nicholas Seckar]

* Fix routing to correctly determine when generation fails. Closes #6300. [psross].

* Fix broken assert_generates when extra keys are being checked. [Jamis Buck]

* Replace KCODE checks with String#chars for truncate.  Closes #6385 [Manfred Stienstra]

* Make page caching respect the format of the resource that is being requested even if the current route is the default route so that, e.g. posts.rss is not transformed by url_for to '/' and subsequently cached as '/index.html' when it should be cached as '/posts.rss'.  [Marcel Molina Jr.]

* Use String#chars in TextHelper::excerpt. Closes #6386 [Manfred Stienstra]

* Install named routes into ActionView::Base instead of proxying them to the view via helper_method. Closes #5932. [Nicholas Seckar]

* Update to latest Prototype and script.aculo.us trunk versions [Thomas Fuchs]

* Fix relative URL root matching problems. [Mark Imbriaco]

* Fix filter skipping in controller subclasses.  #5949, #6297, #6299 [Martin Emde]

* render_text may optionally append to the response body. render_javascript appends by default. This allows you to chain multiple render :update calls by setting @performed_render = false between them (awaiting a better public API).  [Jeremy Kemper]

* Rename test assertion to prevent shadowing. Closes #6306. [psross]

* Fixed that NumberHelper#number_to_delimiter should respect precision of higher than two digits #6231 [phallstrom]

* Fixed that FormHelper#radio_button didn't respect an :id being passed in #6266 [evansj]

* Added an html_options hash parameter to javascript_tag() and update_page_tag() helpers #6311 [tzaharia]. Example:

    update_page_tag :defer => 'true' { |page| ... }

  Gives:

    <script defer="true" type="text/javascript">...</script>
    
  Which is needed for dealing with the IE6 DOM when it's not yet fully loaded.

* Fixed that rescue template path shouldn't be hardcoded, then it's easier to hook in your own #6295 [mnaberez]

* Fixed escaping of backslashes in JavaScriptHelper#escape_javascript #6302 [sven@c3d2.de]

* Fixed that some 500 rescues would cause 500's themselves because the response had not yet been generated #6329 [cmselmer]

* respond_to :html doesn't assume .rhtml.  #6281 [Hampton Catlin]

* Fixed some deprecation warnings in ActionPack [Rick Olson]

* assert_select_rjs decodes escaped unicode chars since the Javascript generators encode them.  #6240 [japgolly]

* Deprecation: @cookies, @headers, @request, @response will be removed after 1.2. Use the corresponding method instead.  [Jeremy Kemper]

* Make the :status parameter expand to the default message for that status code if it is an integer. Also support symbol statuses. [Jamis Buck]. Examples:

    head :status => 404        # expands to "404 Not Found"
    head :status => :not_found # expands to "404 Not Found"
    head :status => :created   # expands to "201 Created"

* Add head(options = {}) for responses that have no body. [Jamis Buck]. Examples:

    head :status => 404 # return an empty response with a 404 status
    head :location => person_path(@person), :status => 201

* Fix bug that kept any before_filter except the first one from being able to halt the before_filter chain.  [Rick Olson]

* strip_links is case-insensitive.  #6285 [tagoh, Bob Silva]

* Clear the cache of possible controllers whenever Routes are reloaded. [Nicholas Seckar]

* Filters overhaul including meantime filter support using around filters + blocks.  #5949 [Martin Emde, Roman Le Negrate, Stefan Kaes, Jeremy Kemper]

* Update RJS render tests. [sam]

* Update CGI process to allow sessions to contain namespaced models. Closes #4638. [dfelstead@site5.com]

* Fix routing to respect user provided requirements and defaults when assigning default routing options (such as :action => 'index'). Closes #5950. [Nicholas Seckar]

* Rescue Errno::ECONNRESET to handle an unexpectedly closed socket connection. Improves SCGI reliability.  #3368, #6226 [sdsykes, fhanshaw@vesaria.com]

* Added that respond_to blocks will automatically set the content type to be the same as is requested [DHH]. Examples:

    respond_to do |format|
      format.html { render :text => "I'm being sent as text/html" }
      format.rss  { render :text => "I'm being sent as application/rss+xml" }
      format.atom { render :text => "I'm being sent as application/xml", :content_type => Mime::XML }
    end

* Added utf-8 as the default charset for all renders. You can change this default using ActionController::Base.default_charset=(encoding) [DHH]

* Added proper getters and setters for content type and charset [DHH]. Example of what we used to do:

    response.headers["Content-Type"] = "application/atom+xml; charset=utf-8"
  
  ...now:
  
    response.content_type = Mime::ATOM
    response.charset      = "utf-8"

* Updated prototype.js to 1.5.0_rc1 with latest fixes. [Rick Olson]

  - XPATH support
  - Make Form.getElements() return elements in the correct order
  - fix broken Form.serialize return

* Declare file extensions exempt from layouts.  #6219 [brandon]
    Example: ActionController::Base.
