0.2 A Note on Versions

This document describes the Player robot server version 1.5. It applies to Player versions > = 1.5 (at least until we put out another manual). Since the previous version, many things have likely changed. Thus, this manual does not apply to older versions of Player. You can find an older manual at the Player homepage: http://playerstage.sourceforge.net/doc/doc.html
In addition to providing access to physical hardware, Player is also the interface to the robot simulators Stage and Gazebo. The three software packages evolve independently, and so their version numbers have no meaningful correspondence (it used to be the case that Player and Stage versions were matched exactly; this is no longer true). For information on which versions of Player and the simulators are compatible, see the online FAQ: http://playerstage.sourceforge.net/faq.html
