upgrade to version 0.27. alignment with xotcl-core 0.38 (use cr_item.name instead of cr_revisions.title), change page_title to title (potential incompatibility) to rely more strictly to the CR data model (most files are effected).
new release (0,24) of xowiki, support for link types, sample glossary link types with ajax based popup to display glossary items. Popup is based on the overlib package with an artistic license.
