 Ruby on Rails 2.3 Release Notes
 ===============================
 
-Rails 2.3 delivers a variety of new and improved features, including pervasive Rack integration, refreshed support for Rails Engines, nested transactions for Active Record, dynamic and default scopes, unified rendering, more efficient routing, application templates, and quiet backtraces. This list covers the major upgrades, but doesn't include every little bug fix and change. If you want to see everything, check out the link:http://github.com/rails/rails/commits/master[list of commits] in the main Rails repository on GitHub.

 === Dynamic Scopes

Well, now you can have dynamic scope methods. The idea is to put together syntax that allows filtering on the fly <i>and</i> method chaining. For example:

+=== Reconnecting MySQL Connections
+
+MySQL supports a reconnect flag in its connections - if set to true, then the client will try reconnecting to the server before giving up in case of a lost connection. You can now set +reconnect = true+ for your MySQL connections in +database.yml+ to get this behavior from a Rails application. The default is +false+, so the behavior of existing applications doesn't change.

+=== HTTP Digest Authentication Support

+Rails now has built-in support for HTTP digest authentication. To use it, you call +authenticate_or_request_with_http_digest+ with a block that returns the user’s password (which is then hashed and compared against the transmitted credentials):

 === More Efficient Routing
 
 There are a couple of significant routing changes in Rails 2.3. The +formatted_+ route helpers are gone, in favor just passing in +:format+ as an option. This cuts down the route generation process by 50% for any resource - and can save a substantial amount of memory (up to 100MB on large applications). If your code uses the +formatted_+ helpers, it will still work for the time being - but that behavior is deprecated and your application will be more efficient if you rewrite those routes using the new standard. Another big change is that Rails now supports multiple routing files, not just routes.rb. You can use +RouteSet#add_configuration_file+ to bring in more routes at any time - without clearing the currently-loaded routes. While this change is most useful for Engines, you can use it in any application that needs to load routes in batches.

+=== Localized Views
+
+Rails can now provide localized views, depending on the locale that you have set. For example, suppose you have a +Posts+ controller with a +show+ action. By default, this will render +app/views/posts/show.html.erb+. But if you set +I18n.locale = :da+, it will render +app/views/posts/show.da.html.erb+. If the localized template isn't present, the undecorated version will be used. Rails also includes +I18n#available_locales+ and +I18n::SimpleBackend#available_locales+, which return an array of the translations that are available in the current Rails project.

 === Other Action Controller Changes
 
 * ETag handling has been cleaned up a bit: Rails will now skip sending an ETag header when there's no body to the response or when sending files with +send_file+.
 * The fact that Rails checks for IP spoofing can be a nuisance for sites that do heavy traffic with cell phones, because their proxies don't generally set things up right. If that's you, you can now set +ActionController::Base.ip_spoofing_check = false+ to disable the check entirely.

This supports both filters (to perform regex-based substitutions on backtrace lines) and silencers (to remove backtrace lines entirely). Rails automatically adds silencers to get rid of the most common noise in a new application, and builds a +config/backtrace_silencers.rb+ file to hold your own additions. This feature also enables prettier printing from any gem in the backtrace.
