= New Features

* The render_each method in the render_each plugin now accepts a
  block.  If passed a block, instead of returning a concatenation
  of the rendered template output, it yields each rendered template
  output, and returns nil.  This allows for use in the case where you
  want to wrap the template output:

    <% render_each([1,2,3], :foo) do |text| %>
      <p><%= text %></p>
    <% end %>

  If can also be used to reduce memory usage even in the case where
  you are not wrapping template output.  Instead of:

    <%= render_each([1,2,3], :foo) %>

  You can do:

    <% render_each([1,2,3], :foo) %><%= body %><% end %>

  This will avoid building a potentially large unnecessary intermediate
  string.

* The capture_erb plugin now supports a returns: :buffer method and
  plugin option.  When this option is provided, the capture_erb method
  returns the buffer instead of the return value of the block passed
  to it.  This better handles cases where the template ends in a
  conditional:

    <% value = capture_erb do %>
      Some content here.
      <% if something %>
        Some more content here.
      <% end %>
    <% end %>
