Backward Compatibility and Migration Notes

General Notes

  • When upgrading make sure you compare and merge the following XWiki configuration files since some parameters may have been modified, removed or added:
    • xwiki.cfg
    • xwiki.properties
    • web.xml
    • hibernate.cfg.xml
  • Add xwiki.store.migration=1 in xwiki.cfg so that XWiki will attempt to automatically migrate your current database to any new schema. Make sure you backup your Database before doing anything.

Issues specific to XWiki 15.5.1

The rendered changes now only download images to compare their content from trusted domains. Also, several configuration options have been added to disable the feature of downloading images for comparison or to change the maximum size of downloaded images. Make sure you review these settings to make sure the comparison of images works as expected.
