*SVN*
|
||||
|
||||
* Added Base#render_to_string to parse a template and get the result back as a string #479
|
||||
|
||||
* Fixed that send_file/data can work even if render* has been called before in action processing to render the content of a file to be send for example #601
|
||||
|
||||
* Added FormOptionsHelper#time_zone_select and FormOptionsHelper#time_zone_options_for_select to work with the new value object TimeZone in Active Record #688 [Jamis Buck]
