The Official Site of Atlanta Braves: Official Info: Press Release
Braves add three players to 40-man roster

Trust the Braves to bury the lede at the very end of the release:

The Braves also activated four players from the 60-day disabled list: infielder Willy Aybar, left-handed pitchers Mike Gonzalez and Mike Hampton and right-handed pitcher Anthony Lerew. Infielder Pete Orr was designated for assignment to reduce the roster to 40.

Whoo-hoo! Break out the Labatt’s!

To be clear, this doesn’t definitely mean the end of Orr in a Braves uniform, because nobody’s going to claim him, because he sucks. So he could easily stay in the organization and sneak onto the roster again.

The three added were Charlie Morton, Jairo Cuevas, and Zach Schreiber, all pitchers.
