New features in this Adobe Illustrator release include:

Package Files – a long-requested featurethat allows designers to automatically collect all the files used in an Illustrator project, including linked graphics and fonts, into a single folder helping make handoffs and sharing of projects more efficient and error-free.

Unembed Images – a new capability that enables production artists to quickly unembed images that have been embedded into an Illustrator file by other designers or customers, eliminating much wasted time in day-to-day production work.

Links Panel Enhancements – a new feature enhancement that allows users to access and track information on any artwork placed in an Illustrator file much quicker. What used to require multiple clicks to ensure all placed graphics meet necessary requirements for output is now surfaced up front.
