These spacecraft (and CubeSats) were onboard the Atlas V launch, yesterday:

• X-37B OTV-4 (USA 261) • GEARRSAT 2 (GEARRS 2) • LightSail A • OptiCube 1 (O/C 1) • OptiCube 2 (O/C 2) • OptiCube 3 (O/C 3) • USS Langley • AeroCube 8A (IMPACT A) • AeroCube 8B (IMPACT B) • BRICSat-P • PSat A (ParkinsonSat A) http://space.skyrocket.de/doc_chr/lau2015.htm

Scroll down the AMSAT-UK web site http://amsat-uk.org/2015/05/20/lightsail-1-launch/ for a very good picture of the Dispenser, that was attached to the Centaur second stage. After OTV-4, X-37B was released, the Centaur stage performed a orbital maneuver for release of these small satellites. -- BTW, Centaur has now been used for 51-1/2 years by USA on Atlas (and retired Titan boosters).
