Joomla Project coordinator Wilco Jansen recently updated the Joomlaverse about the status of Joomla 1.6, the next version of Joomla. Joomla 1.6 is expected later in 2009, but is currently in pre-alpha stage.
Writing on the Joomla Project's Coordinator Blog, Jansen takes the reader through the thought process and development roadmap for Joomla 1.6. He outlines the updated list of features that are certain to be in this next version of Joomla, including more granual access control levels to give permissions to more discrete groups of users.
Jansen also touches on a common complaint about Joomla related to the content hierarchy limitations, and states that Joomla 1.6 will "implement unlimited depth categories (but not multi-mapping)."
