"Free Software and Open Source" — it really matters !
Some of these new features include:
As is the tradition in the Tiki community, most of the *.tiki.org sites have been upgraded to 9.x before it was officially released. This helps find and fix bugs. Please see: Dogfood.
The release of Tiki 9.0 marks the close of the Tiki 8.x branch. All Tiki Administrators using an 8.x version are encouraged to upgrade to Tiki 9.0. Tiki 9.x is a LTS (Long Term Support) version, and it will be supported until November 2015.
The Tiki community has also decided to extend long term support (LTS) for Tiki 6.x support until May 2014.
Please see: Version Lifecycle
