Full list of issues fixed and Dashboard for XWiki 15.10.2.

For Developers

• New API to safely evaluate XObject properties: A new API to provide safe evaluation of XObject properties has been introduced to allow developers to control which properties from which XClasses should be evaluable, and how they should be evaluated. For XObjects that have assigned evaluators, the evaluated properties can be recovered in scripts through the new evaluate() method.

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.

API Breakages

The following APIs were modified since XWiki 15.10.1:

Unstable APIs

Not real backward compatibility breakages since they were done on APIs marked @Unstable (a.k.a Young APIs). Thus it's part of the contract that they can be broken until they become stable. They're listed purely for reference in case you decided to still use them (and thus agreed to be broken).

• Unstable API. The Optional wrapper proved to be useless.
  • Violation type:
    java.method.returnTypeChanged
  • Code:
    ## Old:
    method java.util.Optional<org.xwiki.extension.index.security.review.ReviewsMap> org.xwiki.extension.security.analyzer.ReviewsFetcher::fetch() throws org.xwiki.extension.security.internal.ExtensionSecurityException
    
    ## New:
    method org.xwiki.extension.index.security.review.ReviewsMap org.xwiki.extension.security.analyzer.ReviewsFetcher::fetch() throws org.xwiki.extension.security.internal.ExtensionSecurityException
