Adobe has been busy, they've revamped their PDF reading software and taken the roman-based numbering system in their grace with the release of "Adobe Reader X" - it includes better security and also a change UI. Adobe's flagship PDF creation software, Acrobat has also been upgraded.

Reader X will provide a sandbox to limit the access that PDF-based scripts can have over the users OS, in turn limiting the attack range that PDF's usually provide - lately PDF readers have been the victims of attacks from hackers.

Some of the new features include the ability to view and interact with PDF files that contain a wider variety of content types such as, drawings, email, spreadsheets, videos and multimedia elements. X will allow you to make notes and share feedback with others within the PDF document using Sticky Notes and Highlighter tools.

Reader X also allows the user to choose the reading mode to fit more content on the screen or two-up mode to view page spreads - keyboard shortcuts give you access to print, zoom, and find within the browser. Protected Mode in Reader gives you peace of mind with safer viewing of PDF files.
