Released on January 8, 2013, Adobe Reader XI (version 11.0.01) was the first major quarterly update for the XI generation, which had originally launched in October 2012.

For system administrators managing IT infrastructure at the time, deploying 11.0.01 was a mandatory step to ensure network security. It ensured that the new features introduced in XI did not come at the cost of system integrity.
