This morning Adobe formally announced Acrobat X.  While there are several interesting new features, two captured my attention:

1) PDF Portfolios allow multiple documents (including different formats) to be placed into a single file for distribution.  If you need to send a client several related documents this allows you to put them together into a neat bundle rather than sending multiple attachments that they might open in any order.

2) While the release didn’t make mention of security, Adobe X includes a Protected Mode — a sandboxing technology based on Microsoft’s Practical Windows Sandboxing technique. It is similar to the Google Chrome sandbox and Microsoft Office 2010 Protected Viewing Mode. You can find more details on the Adobe Secure Software Engineering Team’s blog.

Protected Mode will also be included in the new version of Adobe Reader. The new software is expected to be available in November.
