I released a new 9.2 version of the Confluence tools. It mainly contains bugfixes compared to 9.1 but I named it 9.2 instead of 9.1.7 because it also contain an important change.
The space key is used instead of the space name now. This is to better follow Confluence logic where the space key is the one you see in the source links and more importantly in the URL.
See http://extensions.xwiki.org/xwiki/bin/view/Extension/Confluence/ for more details.
