Backward Compatibility and Migration Notes

General Notes

You may also want to import the default wiki XAR in order to benefit from all the improvements listed above.

Solr Index Format Change

If you're upgrading from XWiki 4.5.x to this version you'll need to perform a full re-indexation when using the Solr Search. This because in XWiki 4.5.x the Solr search was experimental and we've completely changed the indexing format in XWiki 5.1.

Email Address Obfuscation

In 4.2 we introduced a new object property type called Email that can be used to store email addresses. In 5.1 we decided to use this new property type in the user profile to store the user email address. With this change we also introuced a defaut custom displayer for the Email property type that obfuscates the email address in view mode. As a consequence the user profile email address became obfuscated by default. Starting with 5.2 we allow you to toggle the email address obfuscation from the administration. What is important to know is that the email address obfuscation is off by default. So if you upgrade from 5.1 and you want to preserve the obfuscation then you need to enable it from the administration.

Instance Identifier

XWiki now creates a unique identifier in the database (this is used by the new Active Installs module and will be used in the future by the Extension Manager to identify your instance for example). You need to verify that your hibernate.cfg.xml file has the following mapping definition next to the existing mapping definitions:

API Breakages

The following APIs were modified since XWiki 5.1:

• Moved to xwiki-commons-legacy-properties

• This method should never have existed

• Moved from xwiki-rendering-api to xwiki-rendering-xml

• This field is not meant to be be modified, the final was just forgotten.

• Not an API. This should be internal.

• Has been moved to xwiki-platform-feed-api since it was the only module using it. We also dropped jTidy in favor of HTMLCleaner.

• Google API plugin has been retired

• Return the number of imported documents

• The JPQLParser generates source code (that should be internal but it is not) and the grammar has changed a bit.
