First off, the Acrobat 9 family has now been officially released. The upgrade version everyone’s been waiting for is available for purchase and includes a number of buzz worthy goodies such as Flash integration and document synchronization. Acrobat 9 also has the ability to compare different versions of a single PDF and an enhanced webpage to PDF conversion feature.

If you want to check out the features in depth, free trials for all three versions are available on the Adobe site.

The other announcement this week—a new Adobe Reader and Acrobat vulnerability has been discovered. The security bulletin on the Adobe site claims that the vulnerabilities found in the current Reader and Acrobat versions 8.0 through 8.1.2 have the ability to crash the applications, which could allow malicious users to take over your system.

This probably has you worried if your PDF apps are prone to stalling and then crashing moments later. Fortunately, patches are available for the affected software versions. For more information on this security threat visit the Adobe Security Bulletin.
