ATK 5.6.0 released

• 5 new attributes, from a simple attribute for manipulating URLS to a flexible calculator that can add columns containing arbitrary calculations of other attributes, and a generic attribute that can turn any other attribute into an internationalised data field.
  
• A new 'shuttle' relation for easy selection of records in many-to-many relationships.
  
• 2 new themes, 'macoslike' and 't3skin'. The latter creates a Typo3 4.0 look for ATK, useful for integrating ATK applications into a Typo3 environment.
  
• An AJAX based generic data structure search functionality.
  
• An atkMessageQueue for relaying messages to the user.
  
• Many API enhancements (new methods, new features and new flags)

And many more fixes and improvements. The complete change log can be found on the release notes page.
