Adobe announced Thursday an update of the Flash player to version 10.0.42.34 that addresses various and sundry security issues. The company also announced that version 10.1 of the player will be the last to support PowerPC G3-based Macs.

In a note on its Support site, Adobe said, "Adobe will be discontinuing support of PowerPC-based G3 computers and will no longer provide security updates after the Flash Player 10.1 release. This unavailability is due to performance enhancements that cannot be supported on the older PowerPC architecture."

As for today's update, the release notes for the patch say, "Critical vulnerabilities have been identified in Adobe Flash Player version 10.0.32.18 and earlier. These vulnerabilities could cause the application to crash and could potentially allow an attacker to take control of the affected system."

Adobe provides a Web page for users to check the version of Flash installed on your system. That link will tell you if Flash is installed, what version number it is, and whether or not it is in debug mode, for those keeping score at home.

You can download the update at Adobe's download site. It is a 5.7MB Universal Binary download.
