There are two major changes in the architecture of Rails applications: complete integration of the "Rack": modular web server interface, and renewed support for Rails Engines.

+Object#tap+ is an addition to "Ruby 1.9": and 1.8.7 that is similar to the +returning+ method that Rails has had for a while: it yields to a block, and then returns the object that was yielded. Rails now includes code to make this available under older versions of Ruby as well.
+h4. Swappable Parsers for XMLmini
+The support for XML parsing in ActiveSupport has been made more flexible by allowing you to swap in different parsers. By default, it uses the standard REXML implementation, but you can easily specify the faster LibXML or Nokogiri implementations for your own applications, provided you have the appropriate gems installed:

The +Time+ and +TimeWithZone+ classes include an +xmlschema+ method to return the time in an XML-friendly string. As of Rails 2.3, +TimeWithZone+ supports the same argument for specifying the number of digits in the fractional second part of the returned string that +Time+ does:

+h4. rake gem Task Rewrite
+The internals of the various <code>rake gem</code> tasks have been substantially revised, to make the system work better for a variety of cases. The gem system now knows the difference between development and runtime dependencies, has a more robust unpacking system, gives better information when querying for the status of gems, and is less prone to "chicken and egg" dependency issues when you're bringing things up from scratch. There are also fixes for using gem commands under JRuby and for dependencies that try to bring in external copies of gems that are already vendored.
