Adobe has recently released new versions of Reader for both Windows and Mac OS X users, so in case you’re one of the several millions consumers running this app right now, make sure you deploy the update as soon as possible.
Adobe Reader XI 11.0.6 and X 10.1.9 are now up for grabs for everyone, but the parent company is yet to provide us with official details about the new builds.
Basically, both of them are most likely focused on fixing bugs and other performance bugs, so expect the new builds to work faster and be more reliable on both Windows and Mac.
Of course, the feature lineups remain basically unchanged, and both versions come at absolutely no charge regardless of the operating system you are currently running.
