<commit_before>## Rails 4.0.0 (unreleased) ##

*   Remove support for parsing XML parameters from request. If you still want to parse XML
    parameters, please install `actionpack-xml_parser' gem.

    *<NAME>*

*   Fix `time_zone_options_for_select` to call `dup` on the returned TimeZone array.

    Previously if you supplied :priority_zones options to `time_zone_options_for_select`
    the memoized ActiveSupport::TimeZone.all array would be mutated.  Calling
    `dup` prevents mutation of the main TimeZones array.

    *<NAME>*

*   Remove support for parsing YAML parameters from request.

    *<NAME>*

*   Add a message when you have no routes defined to both `rake routes` and
    GET "/rails/info/routes" that lets you know you have none defined and links
    to the Rails guide on the topic.

    *<NAME>*

*   Change `image_alt` method to replace underscores/hyphens to spaces in filenames.

    Previously, underscored filenames became `alt="A_long_file_name_with_underscores"`
    in HTML, which is poor for accessibility. For instance, Apple's VoiceOver Utility
    pronounces each underscore. `A_long_file_name` thus would be read as `A underscore
    long underscore file underscore name.` Now underscored or hyphenated filenames
    (both of which are very popular naming conventions) read more naturally in
    screen readers by converting both hyphens and underscores to spaces.

    Before:

        image_tag('underscored_file_name.png')
        # => <img alt="Underscored_file_name" src="/assets/underscored_file_name.png" />
