The latest version (2.3) was released in 2013-03-20 and it is compatible with the confluence version 5.5.6.
I would think that this version is also compatible with the 5.6 but was not updated in the Atlassian market place yet. As far as I know, there's no ETA for this plugin to be released a new version.
