This is the release notes for XWiki Commons, XWiki Rendering and XWiki Platform. They share the same release notes as they are released together and have the same version.

This release brings in the ability to set password policies in order to define the complexity of the passwords chosen for users authentication. This version provide a lot of bugs fixes and also represents a stabilization phase after many dependencies upgrades.

New and Noteworthy (since XWiki 11.8.1)

Full list of issues fixed and Dashboard for 11.9.

For Users

No changes!

For Admins

Password Security Policy

 
It is now possible to chose some password policy rules that are applied when passwords are chosen (for registration) or when they are changed (by users or administrators).
The password policy rules are available in the Administration > Users & Rights > Registration.

You might find more details on the User Management.

Miscellaneous

• Live storage of job log: The log of the job is now stored on the filesystem next to the statux.xml in live:

  • very low memory footprint
  • it's possible to see the log even of the status is not yet serialized

• Main wiki descriptor used in path based mode: The main wiki descriptor is now also used to find out the the protocol, the domain and the port to use when generating an URL in path based mode in a background thread (typically the mails).

For Developers

Live storage of job log

 
JobStatus#getLog() is now deprecated and replaced by JobStatus#getLogTail() which provide more streamed APIs to navigate in the log.

Miscellaneous

• Bypass log grabbing: It's now possible to force a log to end up in the main log even when during a job that is supposed to grab it.

• Execution context push/pop: Helpers has been adding in ExecutionContextManager to have a better control on the way to push/pop ExecutionContext instances. See Context Module for more details.

• Document default locale: Added a script API to set the document default locale

• 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 11.9

• the main wiki descriptor is now also used to find out the the protocol, the domain and the port to use when generating an URL in path based mode in a background thread (typically the mails). You might want to make sure what's in it is accurate to avoid bad suprises.
