'PDF packages' have been rebranded 'PDF Portfolios'. PDF portfolios sport built-in navigation features and use branded interface templates.
PDF portfolios allow you to collect and organize data of any kind, such as photos, videos, spreadsheets, text, PDF documents and generally files of any kind. Their integrated user interface based on interactive templates gives PDF portfolios a touch of sophistication. As a result, even a random collection of dull text documents will look good in a PDF portfolio without much effort on your part.

Native support for Flash in Acrobat has finally become reality. Acrobat 9 Pro can embed Flash video, H.264 video and Flash animations into a PDF file which can then be viewed directly in Adobe Reader. There is no need for a special media player.
Some of the most significant changes in Acrobat 9 Pro affect the preflight feature. Preflight profiles are now easier to inspect and manage. For the first time, you can easily run single checks (such as "Image is not CMYK or spot") or single fix-ups (such as "Discard invalid links") in addition to a full-blown preflight based on a complete profile.

The new Standards pane in the Preflight dialog incorporates a wizard, which walks you through the process of creating a standard-compliant PDF document from an existing file. The success of the conversion depends on the outcome of the preflight, but thanks to a more explanatory results list, it is much more clear what, if anything, needs fixing.

Adobe has extended the support for standards in Acrobat 9, adding an updated implementation of PDF/X-4 along with PDF/E-1, PDF/X-4p and PDF/X-5pg, among others.
A separate command allows you to browse the internal PDF structure.
OK, so you want to stamp your document. Maybe you need to give reviewers some advice about the document's status or sensitivity. This tip from author Ted Padova demonstrates how to add stamps with the Stamp Tool along with related comments.
