As part of the 1.0.2 release we updated the JumpBoxes for MediaWiki and Wordpress to contain the latest releases of those applications.

The  JumpBox for MediaWiki  was updated to contain MediaWiki 1.11.0 and you can see what changed in this version of MediaWiki in their  release notes. This was a fairly minor update to MediaWiki.

The  JumpBox for Wordpress  was updated to contain Wordpress 2.3 and you can see what changed in this version of Wordpress  here. This was a fairly significant update to Wordpress.

The typical  JumpBox migration mechanism  can be used to move existing installations to these new JumpBoxes.
