For Developers

Context and cache inconsistency hunting

• XWikiCacheStore make sure to recalculate the cache based based on whatever the actual store return instead of assuming the passes XWikiDocument is what it will received

Backward Compatibility and Migration Notes

General Notes

When upgrading make sure you compare your xwiki.cfg, xwiki.properties and web.xml files with the newest version since some configuration parameters may have been modified or added. Note that you should add xwiki.store.migration=1 so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.
