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 16.10.9

XWiki now overwrite the standard application server request URL resolution

We had too many erratic/buggy behaviors with various application servers not properly following proxy headers, so we decider to not trust them anymore: XWiki now overwrite in a Servlet filter the behavior of ServletRequest#getScheme(), ServletRequest#getServerName(), ServletRequest#getServerPort() and HttpServletRequest#getRequestURL() so those should now have the same behavior no matter the application server used and its setup.

API Breakages

The following APIs were modified since XWiki 16.10.8:

No breakage!
