Hi, Thanks for the good question.
It's because of the SparkVersion class is introduced after 0.5.0. Until 0.5.0, once Zeppelin is compiled, it works only with a Spark version that used in compiling. But from 0.5.6, Zeppelin can work with any (supported) version of Spark once it is compiled, and SparkVersion provides informations such as Spark versions that supported from Zeppelin and feature differences between versions. Hope this helps.
